Specialty chemicals for water base coating system
Water soluble cationic polymer (poly(allylamine) , poly(diallylamine))
Poly(allylamine)(PAA) and poly(diallylamine)series (PAS) are water base, cationic polymers, having exceptionally the unique characteristics, versatile applications below:
- Dye fixing agent for receptacle latter for ink jet media (paper, film and fabric)
- Textile dye fixing agent for direct/indirect dye
- Surface leveling agent in electrolytic plating
- Anchor coating agent for fluoro elastomer
- Cross linking agent for epoxy, urethane polymer and more
- Intermediate for drugs
Blocked isocyanate cross-linking agent
Blocked isocyanate, which is stable at room temperature, however dissociates to regenerate isocyanate functionality under the influence of heat.
A temperature over 120oC (248 oF) is necessary to release the blocking agent. The resulting isocyanate will react with active hydrogen-containing compounds to form more thermally stable urethane or urea linkage. Blocked isocyanate can be added directly to most waterborne formulations and can be utilized in coatings for wood, leather, inks, adhesives, textiles and water base coatings for metal. Our product BI-792 is VOC free cross linking agent.

Oxazoline functional cross-linking agent
APR 200 Series are unique polymer emulsions containing pendant oxazoline groups designed to act as an effective waterborne crosslinking agent for polymer emulsions containing carboxyl functionality. The APR-200 series resins demonstrate excellent adhesion to polyester and other substrates due to the oxazoline groups. APR 200 series is best used for applications requiring Low-Temperature Curing , Long Pot-Life, VOC Free and replacement of azilidine.
