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.


(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.


(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.


Resin: 24kg/barrel

Hardener: 6kg/barrel

The packaging can be adjusted according to customer's requirement.
