Akfix P645 specifications make it the right PU sealant for metal joints exposed to fuel, oil, vibration, and thermal cycling — bodywork, panel work, container fabrication, generator enclosures, and metal roofing. For pure construction weathersealing (concrete expansion joints, window perimeters), a neutral silicone (Akfix 915N) is typically more cost-effective. For mirror or sensitive-substrate bonding, use Akfix 900N neutral silicone.

What the Akfix P645 Is Built For

The Akfix P645 is the workhorse polyurethane metal sealant. Use it for:

Automotive and transport bodywork:

• Sealing and bonding metal panel joints during panel-beating and body-repair work.
• Sealing seams in vehicle body shells during restoration and fabrication.
• Sealing around windscreen and rear screen bonding joints (where the windscreen is bonded, use Akfix specific windscreen adhesive — call to discuss).
• Sealing around sunroof and roof-rack mounting points.
• Sealing around vehicle body trim and moulding mounting points.
• Sealing underbody and chassis components (where a fuel-and-oil-resistant sealant is required).

Container and trailer fabrication:

• Sealing panel joints in shipping-container conversions (offices, accommodation, ablution units).
• Sealing joints in trailer and truck-body fabrication.
• Sealing seams in metal enclosures, cabinets, and generator housings.
• Sealing around hatches, doors, and access panels on metal enclosures.

Metal roofing and cladding:

• Sealing overlap joints in metal roofing sheets (where paintability is required for colour matching).
• Sealing around roof penetrations — vents, flues, solar mounts, antenna mounts.
• Sealing flashing and trim joints.
• Sealing gutter and downpipe joints.

Generator and machine building:

• Sealing enclosure panels on generator sets, compressor sets, and pump sets.
• Sealing access panels and inspection covers.
• Sealing around control panel and instrument mounting points.
• Sealing joints in fabricated machine frames.

General construction and industrial:

• Sealing joints between metal components and concrete or masonry.
• Sealing joints in pre-engineered metal buildings (PEMB).
• Sealing around steel window and door frames to the structural opening (where paintability and fuel-resistance are required).
• Sealing joints in marine applications above the waterline (deck hardware, hatch frames).

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 (P645 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).

Genuine Akfix P645 vs Counterfeit: What to Check

Counterfeit and expired PU sealants are common in the Kenyan automotive and construction supply market. A cartridge 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 P645 in Kenya, verify the following:

1. Akfix batch number and date code printed on every cartridge. The format is a multi-character batch code with manufacture date. No batch code or no expiry = reject the cartridge.
2. Certificate of Analysis (CoA) available on request for the specific batch — confirms density, viscosity, and Shore A hardness.
3. Cartridge and label quality — genuine Akfix cartridges are HDPE 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 cartridge is often a generic no-name tube with an Akfix label stuck on.
4. Colour and consistency — genuine P645 in black is smooth, deep black, and thixotropic. Expired product is lumpy, separated, or has a hard skin in the cartridge (PU reacts with moisture; once a cartridge 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 P645 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 P645 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 cartridge of original Akfix P645 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 cartridge is opened, the contents cure progressively from the front; plan to use an opened cartridge within 24 hours or fit a replacement nozzle to slow skin formation.

For bulk orders (carton quantities or non-standard colours), call ahead on 0705544817 so we can confirm quantity and reserve stock.

What colours does Akfix P645 come in? Standard stocked colour is black. Grey and white are available on special order — call 0705544817 to confirm availability and lead time.

Can Akfix P645 be used on automotive bodywork? Yes — this is the primary P645 application. P645 is widely used in body shops and panel-beating operations for sealing panel joints, seams, and gaps during body-repair work. The fuel and oil resistance makes it suitable for engine bay and chassis applications. For windscreen bonding (where the adhesive carries the structural load of the windscreen), use a specific windscreen adhesive — call 0705544817 to discuss.

Can Akfix P645 be painted? Yes. P645 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, P645 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.

Can Akfix P645 be used on bare metal? Yes. P645 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 P645 fuel and oil resistant? Yes. P645 is specifically formulated to resist short-term splash exposure to petrol, diesel, motor oil, hydraulic fluid, and most lubricants. 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.

What is the difference between Akfix P645 and Akfix 915N? P645 is a polyurethane (PU) sealant — paintable, fuel-resistant, strong adhesion to metal, for automotive bodywork, container fabrication, metal enclosures, and metal roofing. 915N is a neutral-cure silicone weatherseal — not paintable, UV-resistant, high-movement, for exterior expansion joints, curtain walls, and window perimeters. For metal joints where painting and fuel-resistance are required, use P645. For exterior weather-exposed high-movement joints, use 915N.

What is the difference between Akfix P645 and Akfix AS606? P645 is a polyurethane (PU) sealant — strong adhesion, flexible, fuel-resistant, paintable, for metal joints and demanding applications. AS606 is an acrylic-siliconized sealant — paintable, water-based, low-odour, for interior and sheltered exterior low-movement joints where metal adhesion and fuel-resistance are not required. For metal joints, use P645. For interior painting and decorating work, use AS606.

How long does Akfix P645 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 P645? 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 cartridge. We rotate stock by FIFO and ship the longest remaining shelf life first. Once a cartridge is opened and the nozzle is cut, use within 24 hours or fit a replacement nozzle to slow skin formation. PU sealants are sensitive to moisture ingress — keep nozzles sealed and store opened cartridges with the tip covered.

Do you deliver Akfix P645 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.
