Product  introduction
 
Fenteng CT0012 is a curing agent suitable for the production of impregnated paper with low pressure, it can only be used in urea formaldehyde (UF) resin.
 
CT0012 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.
 
CT0012 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
 

CT0012 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.

CT0012 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.
 

Leak handling

This product is a non-flammable and explosive industrial grade chemical product and cannot be used in any food and medicine.

When the product leaks, it is recommended that the operator wear a dust mask, wear a gas-proof suit, and do not touch the leaked material. When a small amount of leakage occurs, rinse and dilute with a large amount of water. When a large amount of leakage occurs, it should be covered with plastic sheet, and then collected and recycled.

 Related Information

MF resin has high chemical activity, high bonding strength, high water resistance, can experience more than three hours of boiling water, high thermal stability, low temperature curing ability, hardness and wear resistance, strong resistance to chemical agent, excellent electrical insulation.

modified melamine resin is the most commonly used glue material in film paper industry, widely used in impregnation or coating of floor decoration paper, transparent surface paper, and furniture decoration paper surface layer.

UF have low cost, rich raw materials, non-toxic, colorless, good light resistance after curing resin, long-term use does not change color, weak acid, weak base and grease and other media, mildew resistance, good insulation.

UF resin is one of the earliest thermosetting resins developed. It was successfully developed by The British Cyanogen company in 1924, and has been widely used in the wood-based panel industry because of its low cost and reliable bonding properties. UF is also widely used in the production of adhesive paper. It is mainly used in the impregnation of the first line of furniture decoration paper to replace MF and reduce the cost.

Impregnated paper in the production process commonly used additives are curing agent, penetration agent, mold release agent, anti-blocking agent, anti-dust agent, defoaming agent, anti-static agent; For the production of impregnated paper liquid surface with spraying section, wear-resistant paste will also be used. Additive dosage is not large, but it plays an important role in the quality and production process of veneer paper and veneer panel.
