Product  Introduction
 
Fenteng CT0024 is a curing agent suitable for the production of impregnated paper with low pressure, it can only be used in urea formaldehyde (UF) resin.
 
CT0024 can effectively cure UF resin, to prevent UF resin seeping to melamine resin on surface, avoiding poor surface sealing and adhesion of impregnated paper. With CT0024, temperature in the hot pressing can be increased, flow time of UF resin can be prolonged, dry / wet flaw can be reduced, the heat resistance during storage can be increased, storage time can be prolonged.
 
CT0024 doesn't show curing ability at room temperature (25 ℃), and active time after adding is 8-12 hours. After temporary machine maintenance , new patch of glue is not needed, saving work time. At low temperature (< 120 ℃), the curing process is slow, the resin has time spread enough, meanwhile rapid curing at high temperature provides uniformity. Dry/wer flaw, heat mark can be reduced.
 
Product Performance

CT0024 can effectively cure UF resin, to prevent UF resin seeping to melamine resin on surface, avoiding poor surface sealing and adhesion of impregnated paper. With ct0012, temperature in the hot pressing can be increased, flow time of UF resin can be prolonged, dry / wet flaw can be reduced, the heat resistance during storage can be increased, storage time can be prolonged.

CT0024 doesn't show curing ability at room temperature (25 ℃), and active time after adding is 8-12 hours. After temporary machine maintenance , new patch of glue is not needed, saving work time. At low temperature (< 120 ℃), the curing process is slow, the resin has time spread enough, meanwhile rapid curing at high temperature provides uniformity. Dry/wer flaw, heat mark can be reduced.

Product Application

Added to the system with 0.1-0.3% weight of liquid resin, gel time is 5-10 minutes at 100℃water bath.

The amount of curing agent varies with the reactivity and the pH value of the resin. Before used, appropriate curing time should be determined according to the type of impregnated paper, and the accurate dosage of curing agent should be determined by lab testing.

It is suggested to be used for impregnated paper with long-time transportation and long storage time.

Note:
the curing agent should be added at last, after other additives. the curing time should be tested. Only after the curing time reaches the qualified value, can it be poured into the glue tank.
