1. Description:
Flexibond 8211/Flexibond 8200 is a two-component polyurethane adhesive which is applied for structural bonding for various substrates, such as aluminum honeycomb, wood, PU foam, polystyrene foam board, glass fiber-reinforced plastic, aluminum plate and steel plate, etc.
2. Characteristics:
(1) Excellent adhesion to various substrates.
(2) Cures fast, shortens heat or cold setting time.
(3) Solvent free, environmental friendly.
(4) Good humidity and heat resistance.
3. Application
(1) Adhesive Coating:
The recommended dosage is 200-400G/M2. The dosage varies with the roughness of the substrate surface.
(2) Mixing Ratio
Flexibond 8211/Flexibond 8200=4: 1 (by weight)
The resin (8211) should be uniformly stirred before it is mixed with the hardener (8200). Mix the two components uniformly. Mix for 1-2 more minutes after the two components color is well mixed.
(3) Adhesive Coating Temperature:
The adhesion should be taken within its open time. The open time and curing speed will be affected if the temperature is too high or too low.
(4) Pressing:
Raise the pressing pressure as high as possible without affecting the material forming.
(5) Pressing time
The pressing time is 6-8 hours. The adhesive is fully cured in 7 days. The higher the temperature is, the faster the curing is. The pressing time can reach 30 mins under the temperature of 80.
(6) Clean
Recommended Cleaner: Acetone, butanone.
4. Packaging
Resin: 24kg/barrel
Hardener: 6kg/barrel
The packaging can be adjusted according to customer's requirement.
