Epomatt G-151
Epomatt G-151 is a special type of gloss modifier for epoxy-based powder coatings. The product, when cured with o-tolyl biguanide (OTB) or other common epoxy curing agents such as accelerated dicyandiamide provides coatings with good mechanical and chemical resistance properties. Gloss control is achieved by varying the amount of Epomatt G-151 in the formulation. Smooth matt finishes with 60° gloss values ranging from 2% to 70% can be achieved with Epomatt G-151.

Acrylic Crosslinker GMA-300
Acrylic Crosslinker GMA-300 is a glycidyl functional acrylic terpolymer capable of reacting with carboxyl and amine functional compounds to form durable coatings. It can be used in combination with other resins and curing agents in UV-curable, high-solids, solvent-based and powder coating systems. In powder coatings using carboxylated resins, Acrylic Crosslinker GMA-300 will increase the crosslink density, the mechanical properties and the chemical resistance.
Epoxy Hardener G-91
Epoxy Hardener G-91 is a new type of epoxy hardener producing epoxy powder coatings with excellent mechanical properties and good color stability. Powder coatings with Epoxy Hardener G-91 can be cured at temperatures as low as 130 °C. Reducing energy costs and offering the powder coater flexibility in curing conditions as well as the possibility to coat heat sensitive substrates are the advantages.
Epoxy Hardener G-92
Epoxy Hardener G-92 is a catalyzed phenolic curing agent for use with epoxy and epoxy novolac resins. Powder coatings made with Epoxy Hardener G-92 will exhibit the excellent chemical resistance and mechanical properties for which phenolic epoxy coatings are noted. Epoxy Hardener G-92 allows the formulator the versatility of using differing cure cycles while maintaining performance properties. For example, powder coatings made with Epoxy Hardener G-92 can be “snap” cured in 2 minutes at 200 °C or low temperature cured in 20 minutes at 120 °C while maintaining both mechanical (160 reverse inch pounds impact) and chemical resistance (100+ MEK double rubs) properties.
ESCAT 50
ESCAT 50 is a substituted imidazole catalyst masterbatched at 50% active level in castor wax. Masterbatching the catalyst in castor wax improves the compatibility during extrusion, which helps to assure its uniform distribution in a powder coating. ESCAT 50 is used in powder coatings to accelerate the cure of systems based on the reaction of an epoxy functional resin with a carboxyl functional curing agent.
