Lu'An Jietonda New Material SA316 is a Curing accelerator for powder coatings.Jietonda® SA316 is a special quaternary ammonium compound that can be used as curing accelerator for powder coatings based on Epoxy, Epoxy/Polyester hybrid and Polyester/TGIC to improve curing performance. It may also be used as internal catalyst for carboxyl terminated polyester resin to provide lower cure temperature or shorter baking time.

Lu'An Jietonda New Material K7318 is a Low temperature curing accelerator for powder coatings.Jietonda® K7318 is a new anti-yellowing low temperature curing accelerator,designed for powder coatings based on PES/TGIC and hybrid, to reduce curing temperature or shorten curing time.

Resicure® D-5 is a pulverized grade of dicyamdiamide with an average particle size of about 5 micron. The products contains fumed silica to prevent clumping and improve flow. Typically the product is used with epoxy resin between 3-8 phr. Technicure® D-5 reacts with epoxy resin at temperatures higher than 170°C unless an accelerator is used. Suggested accelerators include Technicure® LC-80, Technicure® LC-100 and substituted ureas such as Technicure® MDU-11M, Technicure® PDU-250M and Technicure® TDU-200M. The type and loading level of an accelerator will provide excellent balance of low temperature reactivity and formulation shelf stability.

Technicure® D-44 is a pulverized grade of dicyandiamide with an average particle size of about 20 micron. The products contains fumed silica to prevent clumping and improve flow. Typically the product is used with epoxy resin between 3-8 phr. Due to larger particle size, the products offers lower exothermic heat than the finer grade of Dicy. Technicure® D-44 reacts with epoxy resin at temperatures higher than 170°C unless an accelerator is used. Suggested accelerators include Technicure® LC-80, Technicure® LC-100 and substituted ureas such as Technicure® MDU-11M, Technicure® PDU-250M and Technicure® TDU-200M. The type and loading level of an accelerator will provide excellent balance of low temperature reactivity and formulation shelf stability.

Technicure® IPDU-8, N-3-(dimethylamino) carbonylaminomethyl-3,5,5-trimethylcyclohexyl-N,N-dimethyl-urea, is a substituted urea. It is used as a dicyandiamide (DICY) accelerator in one-component epoxy resin based formulations. Typically the product is used with epoxy resin and dicyandiamide between 1-3 phr. The loading level of an accelerator will provide balance of low temperature reactivity and formulation shelf stability. Among all substituted ureas as DICY cure accelerators, IPDU-8 offers the most latency.

Technicure® D-10 is a pulverized grade of dicyandiamide with an average particle size of about 10 micron. The products contains fumed silica to prevent clumping and improve flow. Typically the product is used with epoxy resin between 3-8 phr. Technicure® D-10 reacts with epoxy resin at temperatures higher than 170°C unless an accelerator is used. Suggested accelerators include Technicure® LC-80, Technicure® LC-100 and substituted urea such as Technicure® MDU-11M, Technicure® PDU-250M and Technicure® TDU-200M. The type and loading level of an accelerator will provide excellent balance of low temperature reactivity and formulation shelf stability. Technicure® D-10 is available without fumed silica or with a different flow control agent.

EPOTUF 37-685 is a patented amine functional dispersion that is used to formulate two component water-borne epoxy coatings with properties comparable to conventional solvent based two component epoxy coatings.
