- Very fast-curing 2K PU adhesive for repairing cracked plastic parts: trims, wheel covers, bumpers and spoilers. Sandable and paintable, 50 ml double cartridge.
Dekalin DEKAPUR 2K-90 is a very fast-curing, easy-to-use two-component polyurethane adhesive, ideal for structural repairs and joining plastic parts. It cures through a chemical reaction of two components mixed 1:1, forming a durable bond resistant to high temperatures, moisture, fuels, many solvents and most chemicals. The manufacturer developed it for small, quick and lasting repairs.
Key features
- Working time approx. 90 seconds, clamping only approx. 5 minutes
- Sandable after approx. 10 minutes and paintable
- Shore D hardness approx. 63, fills holes and gaps
- Primerless on many plastics, PS and PU foams, wood and filler
- Resistant to moisture, fuels and most chemicals, from -30 to +90 °C
Use in motorhomes and caravans
In motorhomes and caravans DEKAPUR 2K-90 is used for quick repairs of damaged side walls and cracked plastic parts such as trims, wheel covers, rear aprons, bumpers, spoilers, lights and grilles made of ABS, PMMA and GRP. It also fills holes and gaps in metal, wood, stone and glass. On metals you get excellent adhesion after sanding and degreasing with acetone.
For large areas and sandwich panels choose DEKAPUR 2K-6000; for elastic joints and seals, a DEKASYL compound.
How to use, step by step
- Work at +15 to +25 °C. The surface must be flat, dry, free of dust and grease. Sand and clean metals and aluminium.
- Remove the cap by turning it 180°, fit the mixing nozzle and insert the cartridge into a 2K cartridge gun.
- Dispense and discard the first 2-5 cm of insufficiently mixed adhesive.
- Apply the adhesive to one side and join the parts within approx. 90 seconds. Clamp them for approx. 5 minutes.
