Product 1

HCID 159980Resorcinol-formaldehyde resin

Procedure

Resorcinol and formaldehyde were mixed at a mole ratio of 1:2, and then condensation was conducted to obtain a condensate of resorcinol and formaldehyde. 12 wt % of the condensate of resorcinol and formaldehyde and 88 wt % of styrene/butadiene-1,3/vinylpyridine latex were mixed to obtain a resorcinol/formaldehyde-latex (RFL)-based adhesive with a concentration of 20%.
