Product Description
Description:
Flexibond 8205HV is a two-component thixtropic polyurethane adhesive which is suitable to bond wood, fiberglass panel, aluminum panel, steel panel, polyurethane sandwich panel, polystyrene foam panel. The adhesive is suitable for vertical bonding which requires high thixotropy.The product is solvent free, environmental friendly.


Characteristics:
(1) High viscosity version
(2) Excellent adhesion to various substrates without bubble
(3) Fast curing, shortens pressing time
(4) Good thixotropy, non sagging
(5) No irritant gas forming
(6) Resistant to heat and humdity, weather resistant

Application:
(1) Preparation:
Prepare an empty drum. Request: clean and dry.
Mixing tool: Sticks for manual mixing or electric mixer.
Electronic scale: It would be better if the electronic scale can accurately weighting to a decimal point.
 
(2) Surface Treatment of the Substrates:
The substrates should be clean and dry and of no grease, dust, or other contaminations. The substrates can be cleaned by ethanol, acetone. If the metal surface is coated with primer, the discharged agent on the plastic surface is cleaned, or the surface is polished, the adhesion can be increased significantly.
 
(3) Flexibond 8205HV/Flexibond 8200=5:1 (by weight)
Mix for 1-2 more minutes after the two component color is well mixed. Use up the mixer as soon as possible before its pot life, or less frequent principle can be taken.
 
(4) Adhesive Coating:
The adhesive can be coated with serrated scrapers manually or rollers. The adhesive should be coated uniformly on the substrate surface. The recommended dosage is 300-600g/m2. The dosage varies with the roughness of the substrate surface. The adhesive should be coated within its pot life. The specifications can be referred to Figure 1.
 
(5) Pressing:
Substrates have been coated with adhesive should be pressed within open time, or the adhesion strength will be affected. Raise the compounding pressure as high as possible without affecting the material forming. The specifications can be referred to Figure 1.


 
(6) Pressing time
The curing speed and the time to form adhesion vary with the temperature. The curing speed is slower and it takes longer time for pressing as the temperature is lower; the curing speed is faster and it takes shorter time for pressing as the temperature is higher. The pressing time is 5-8 hours under 23ºC. The fully cured time is 7 days. The specifications can be referred to Figure 2.
 
(7) Working Condition
Recommended working condition: temperature 5-30ºC, relative humidity <80ºC. The curing speed will be affected if the temperature is too low. And too much bubble will be formed if the humidity it too high.
 
(8) Clean
Recommended Cleaner: acetone, butanone

Specification:
Resin(Flexibond 8205HV): 25.0kg/pail
Hardener(Flexibond 8200): 5.0kg/pail
The packaging can be adjusted according to customer's requirement.
