Application of urea-formaldehyde resins

- May 17, 2017 -

Crosslinking agent used as adhesive for emulsion. It can be cross-linked with one OH reaction in vinyl acetate emulsion to improve water resistance and heat tolerance. The-CH2OH and NH2 of urea-formaldehyde resin molecules can be associated with the--COOH of acrylic modified emulsion molecules to a certain extent, reduce the hydrophilic group, water resistance to improve, frost resistance also increased.


Can be used for water resistance and dielectric performance requirements of products, such as power strips, switches, machine handles, instrumentation casings, knob, daily necessities, decorations, mahjong tiles, commode cover, also can be used in the manufacture of some tableware.

Urea-formaldehyde resins are the largest varieties of adhesives. In particular, the manufacture of wood-based panels, urea-formaldehyde resins and their modified products accounted for about 90%% of the total amount of adhesive.
