Application

Two-component adhesive must be used within the applicaable period after putting in RE. The length of applicable period is not only related to the polymer content of adhesive, but also other relevant components (like resin, antioxygen, plasticizer, solvent, etc.
When close to the applicable period, usually a few hours or one working day, adhesive becomes more difficult to operate, and viscosity rises soon. Finally, It becomes the irreversible jelly. 100 quality adhesive, Hydroxyl polyurethane (Polyurethane account for around 20%), RE dose 4-7. Chloroprene rubber (Rubber account for around 20%), RICHEST RE does 4-7.
