Frequently Asked Questions
How do polyurethane adhesives cure?
They react with moisture. One surface must hold at least 8% moisture, or you mist the mating face with water. In dry, sealed spaces they will not cure.
Can I use polyurethane adhesive on boats?
Yes. Unobond and Unobond FC carry a D4 water-resistance rating. The bond passed a 72-hour boiling water test, so it suits marine work and full weather exposure.
Do I need to clamp polyurethane adhesive?
Yes. Clamp for at least one hour at 23°C. Use about 50 PSI on softwoods and 150 PSI on hardwoods. Keep the glue line under 0.5 mm for full strength.
Can polyurethane adhesive fill gaps?
No. It is a bond adhesive, not a filler. Strength drops past a 0.5 mm glue line. Fill cracks and gaps with a gap-filling product instead.
How soon can I drive after a windscreen bond?
NP-60 passes its crash test with dual airbags one hour after bonding at 23°C. Do not clean old sealant with alcohol. Alcohol stops the cure.
Does polyurethane adhesive bond near silicone?
No. Keep it away from cured or uncured silicone and hybrid sealants. Apply above 5°C. Cold slows the cure and weakens the bond. Match the product spec to the job conditions before you start.
