RESINS

Resobond A3 & A3W

Resobond A3 is a 100% resorcinol formaldehyde resin that has been specially modified to give high performance bonds on difficult to glue timbers such as jarrah, teak, kapur, chengal, etc. Resobond A3 is classified as a cold setting adhesive for use at temperatures of 20 o C and above. Better quality glue lines will be achieved if the curing temperature is +30 o C. Resobond A3W may be used at lower temperatures.

Resobond RF

Resobond RF is similar to Resobond A3 except for the additives. This makes Resobond RF suitable for radio frequency curing. Resobond RF may also be used as cold setting adhesive in the same way as Resobond A3, however it's performance on difficult to glue timbers such as teak and spotted gum will not be as good.

The addition of 1 – 2% by weight of common salt will decrease the curing time in radio frequency curing, however care must be taken to prevent arcing.

Resobond 220

Resobond 220 is a tannin modified resorcinol formaldehyde adhesive suitable for manufacture of fire-proof doors, container flooring and large surface area bonding of veneers, fire-proof panels, and general timber bonding. When mixed with an appropriate hardener, Resobond 220 forms a strong, weatherproof bond suitable for exposed situations.

Prochemsol recommends elevated curing temperature for Resobond 220 to produce the optimum glue-line, however this adhesive will cure satisfactorily above 25 o C
