Akfix P635 PU Metal Sealant Grey 600ml — Authorized Akfix Distributor, Kenya

Akfix P635 is a one-component, moisture-curing polyurethane sealant formulated specifically for sealing and bonding metal-to-metal and metal-to-construction-substrate joints in automotive, construction, marine, and industrial applications — supplied in a 600ml sausage foil pack in grey. Available now at Startcore Ventures, your authorized Akfix sealants and adhesives distributor on Ngara Road, Nairobi — KES 1,500 inclusive of VAT for the 600ml sausage foil pack, in stock, with full manufacturer traceability and Kenya-wide delivery. P635 is the higher-grade PU sealant in the Akfix range — slightly firmer, slightly stronger, and slightly more fuel-and-oil-resistant than P645 — making it the right choice for demanding bodywork, chassis, generator enclosure, and structural metal-fabrication applications where the sealant joint is load-bearing or exposed to harsh conditions.

Akfix P635 specifications make it the right PU sealant for higher-modulus, higher-strength metal joints where the sealant contributes to the structural integrity of the assembly — load-bearing panel bonds, structural chassis joints, and high-stress fabrication applications. The grey colour in the 600ml sausage format is particularly suited to unpainted or grey-painted metalwork, generator enclosures, and applications where the sealant colour should blend with the surrounding metal. For pure construction weathersealing (concrete expansion joints, window perimeters), a neutral silicone (Akfix 915N) is typically more cost-effective.

What the Akfix P635 Grey 600ml Is Built For

The Akfix P635 grey 600ml sausage format is the higher-grade workhorse polyurethane metal sealant for load-bearing and high-stress metal joints. Use it for:

Automotive and transport bodywork (production-line and restoration):

• Sealing and bonding metal panel joints during panel-beating and body-repair work where higher strength is required.
• Sealing seams in vehicle body shells during restoration and fabrication — load-bearing seams (around windscreen aperture, around rear window aperture, around suspension turrets).
• Sealing underbody and chassis components — chassis seams, subframe mounting points, suspension mounting points.
• Sealing around vehicle body trim and moulding mounting points.

Container and trailer fabrication (high-volume, load-bearing):

• Sealing panel joints in shipping-container conversions (offices, accommodation, ablution units) — grey colour blends with raw or painted container steel.
• Sealing floor-to-wall and wall-to-ceiling joints where structural strength is required.
• Sealing joints in trailer and truck-body fabrication — chassis-to-body joints, cross-member joints.
• Sealing seams in metal enclosures, cabinets, and generator housings.
• Sealing around hatches, doors, and access panels on metal enclosures.

Generator and machine building (production volume, load-bearing):

• Sealing enclosure panels on generator sets, compressor sets, and pump sets — grey sealant blends with grey or green enclosure paint.
• Sealing access panels and inspection covers.
• Sealing around control panel and instrument mounting points.
• Sealing joints in fabricated machine frames and base plates.

Metal roofing and cladding (grey or unpainted metalwork):

• Sealing overlap joints in grey-painted or unpainted metal roofing sheets.
• Sealing standing-seam joints in zinc, aluminium, or coated steel roofing.
• Sealing around roof penetrations — vents, flues, solar mounts, antenna mounts.
• Sealing flashing and trim joints.
• Sealing gutter and downpipe joints.

Construction and industrial (load-bearing metal joints):

• Sealing joints between metal components and concrete or masonry in structural applications.
• Sealing joints in pre-engineered metal buildings (PEMB) — primary frame-to-secondary frame joints.
• Sealing around steel window and door frames to the structural opening.
• Sealing joints in structural steel connections where a flexible, paintable, fuel-resistant sealant is required.

NOT recommended for:

• Aquariums and potable water systems (use a specific aquarium-safe or NSF/ANSI 61 potable-water silicone).
• Food-contact applications (use a specific NSF H1 food-grade sealant).
• Direct structural glazing (use a structural-grade silicone specifically rated for structural glazing).
• Bitumen, asphalt, or polyethylene substrates without a primer (PU does not adhere to these without specific priming — call to discuss).
• Direct continuous immersion in fuel, oil, or aggressive solvents (P635 is for splash exposure; for continuous immersion, use a chemical-resistant grade — call to discuss).
• Expansion joints in concrete where a low-modulus silicone is more appropriate (for high-movement concrete expansion joints, use Akfix 915N).
• Applications where maximum flexibility is required (P645 has higher elongation at break — for maximum flexibility, step down to P645).

Genuine Akfix P635 vs Counterfeit: What to Check

Counterfeit and expired PU sealants are common in the Kenyan automotive and construction supply market. A sausage pack of fake or generic PU labelled as metal sealant will not cure properly, will not adhere to bare metal, and will fail under fuel, oil, or vibration exposure. Before you buy Akfix P635 in Kenya, verify the following:

1. Akfix batch number and date code printed on every sausage pack. The format is a multi-character batch code with manufacture date. No batch code or no expiry = reject the pack.
2. Certificate of Analysis (CoA) available on request for the specific batch — confirms density, viscosity, and Shore A hardness.
3. Sausage pack and label quality — genuine Akfix sausage foil packs are aluminium-foil with a clean, crisp Akfix label including the Akkim branding, "Polyurethane" wording, hazard pictograms (MDI isocyanate sensitiser warning is mandatory), and product code. Counterfeits have fuzzy, off-colour, or mis-spelled labels, and the foil pack is often a generic no-name sausage with an Akfix label stuck on.
4. Colour and consistency — genuine P635 grey is smooth, consistent grey, and thixotropic. Expired product is lumpy, separated, or has a hard skin in the pack (PU reacts with moisture; once a foil pack is opened, moisture enters and skin formation begins). Counterfeits may be the wrong colour, the wrong viscosity, or completely different chemistry (often cheap acrylic or silicone rebadged).
5. Smell — genuine PU sealant has a mild, characteristic isocyanate smell during application. Acrylic sealants have a sweet, mild smell. Silicone sealants have a vinegar (acetic) or neutral smell. If your "PU sealant" smells like vinegar or has no isocyanate smell, it is not PU — return it.
6. Cure test — apply a bead to a piece of bare steel, allow 24 hours, then try to peel the bead off. Genuine P635 will cure to a flexible, fuel-resistant rubber with strong adhesion to metal. Counterfeit or expired product may remain soft, crumbly, or peel cleanly off the substrate.
7. Fuel test — apply a bead to a piece of scrap metal, allow 7 days to fully cure, then immerse in petrol for 1 hour. Genuine P635 will resist the petrol with minimal swelling or softening. Acrylic or silicone will dissolve, swell, or delaminate.
8. Distributor supply — only an authorized Akfix distributor like Startcore can issue a tax invoice tied to the manufacturer batch records. If your seller cannot produce a CoA or trace the batch, walk away.

Startcore supplies every sausage pack of original Akfix P635 Nairobi with a tax invoice, the manufacturer's batch code, and a CoA on request. We rotate stock by FIFO (first in, first out) to ensure the longest remaining shelf life ships first. PU sealants are particularly sensitive to moisture ingress — once a sausage pack is opened, the contents cure progressively from the front; plan to use an opened pack within 24 hours or reseal the nozzle with the original clip.

Is the Akfix P635 grey 600ml available in Nairobi right now? Yes. The 600ml sausage pack in grey is in stock at our Ngara Road store. You can collect same-day, or we can arrange Kenya-wide delivery. For bulk orders (carton quantities), call ahead on 0705544817 so we can confirm quantity and reserve stock.

What is the difference between Akfix P635 and Akfix P645? P635 is the higher-grade PU sealant — higher tensile strength (2.0–3.0 MPa vs 1.5–2.5 MPa), higher Shore A hardness (40–50 vs 35–45), slightly less elongation at break (300–500% vs 400–600%), and slightly better fuel and oil resistance. P645 is the more flexible PU sealant — slightly lower tensile strength and hardness but higher elongation, more suited to high-movement joints where maximum flexibility is required. For load-bearing joints, structural metalwork, and harsh-exposure applications, use P635. For maximum flexibility, high-movement joints, and general metal-sealing applications, use P645.

What applicator gun do I need for the 600ml sausage pack? The 600ml sausage foil pack requires a sausage gun (also called a foil pack gun). Skeleton guns only fit 310ml cartridges. We stock manual sausage guns for workshop use (KES 1,500–2,500) and pneumatic sausage guns for production-line volume (call for pricing). Call 0705544817 to discuss the right gun for your volume and application.

Can Akfix P635 grey be painted? Yes. P635 is paintable once fully cured. Allow the sealant to cure for a minimum of 24 hours before painting (longer in cold or humid conditions). Once cured, P635 accepts most automotive and industrial paint systems — water-based, solvent-based, and 2K — with good adhesion. For best results, lightly abrade the cured sealant surface and prime before applying the topcoat. Grey P635 is particularly suited to grey topcoats — the sealant colour will not show through the paint.

Can Akfix P635 grey be used on bare metal? Yes. P635 adheres excellently to bare metal, primed metal, painted metal, aluminium, stainless steel, galvanised steel, and most other metal substrates. For best adhesion on bare metal, ensure the surface is clean, dry, and free of rust, oil, and dust. Wipe with a suitable solvent cleaner (Akfix Surface Cleaner or isopropanol) before applying.

Is Akfix P635 fuel and oil resistant? Yes. P635 is specifically formulated to resist short-term splash exposure to petrol, diesel, motor oil, hydraulic fluid, and most lubricants — slightly better than P645. This makes it the right sealant for engine bay, chassis, and underbody applications. For continuous immersion in fuel or aggressive solvents, use a chemical-resistant grade — call 0705544817 to discuss.

How long does Akfix P635 take to cure? Skin formation is 30 – 60 minutes at 23°C and 50% relative humidity. Cure rate is 3 – 4 mm per 24 hours. Full cure is 7 – 10 days depending on bead thickness, humidity, and temperature. The joint should not be exposed to fuel, oil, or paint until at least the skin has formed (60 minutes) and ideally until 24 hours have passed. PU cures slower in cold or dry conditions and faster in warm or humid conditions.

What is the shelf life of Akfix P635? 12 months from the date of manufacture in unopened original container, stored at +5°C to +35°C and protected from moisture. The batch code and date are printed on every sausage pack. We rotate stock by FIFO and ship the longest remaining shelf life first. Once a sausage pack is opened and the end is cut, use within 24 hours or reseal the cut end with the original clip and use within a few days. PU sealants are sensitive to moisture ingress — keep the cut end sealed and store opened packs with the clip fitted.

Do you deliver Akfix P635 outside Nairobi? Yes. We deliver Kenya-wide. Same-day in Nairobi, next-day to Mombasa, Kisumu, Eldoret, Nakuru, and all major towns. Delivery cost depends on location and order size. Cash on delivery available for verified trade accounts. Call 0705544817 for a delivery quote.
