 Products

  • Triglycidyl Isocyanurate ( Powder Coating Grade )
    TGIC (Triglycidyl Isocyanurate) is an isocyanurate based crystalline polyepoxide compound. Its molecular weight is 297 (CAS No.2451-62-9). It has good heat resistance, weather resistance, adhesion and high temperature stability....

  • 1. Used as cross-linked hardener for Pure Polester powder coating;

    2. Used as cross-linked hardener for carboxyl-terminated Polyacrylate(PA);

    3. Applied in producing high performance electrical insulating materials, self-extinguishing polymer materials ( as stabilizer of fire-retardant),modified epoxy resin, high effect adhesive, stabilizer for plastic materials, etc.

  • Triglycidyl Isocyanurate ( Electronic Grade )
    TGIC (Triglycidyl Isocyanurate) is an isocyanurate based crystalline polyepoxide compound. Its molecular weight is 297 (CAS No.2451-62-9). It has good heat resistance, weather resistance, adhesion and high temperature stability....

  • 1. Used as cross-linked hardener for carboxyl-terminated Polyacrylate(PA).

    2. Applied in producing high performance electrical insulating material as the cross-linked hardener for PCB inks.

  • HAA ( N,N,N’,N’-Tetrakis (β-hydroxyethy) Adip)
    The curing agent HAA is a tetra-functional group containing N,N,N’,N’-Tetrakis (β-hydroxyethy) adipamide (HAA). It is suitable for curing with carboxyl-terminated polyester or acrylic resin to produce exterior durable powder coatings....

  • Applied as curing agent in TGIC-free based exterior durable powder coatings.
  • Levelling Agent HL988
    Leveling Agent HL988 is a polyacrylate levelling agent with silica carrier. It can be applied to all kinds of thermoplastic and thermosetting powder coatings....

  • 1. HL988 is a general levelling agent. It can be used in pure epoxy, hybrid, pure polyester(TGIC/HAA), polyurethane systems and other kinds of thermosetting powder coating systems. 

    2. HL988 can eliminate the fish-eye and crater phenomena, reduce the coating surface tension, and increase the film gloss.

    3.HL988 can improve the wetting to substrate, and decrease the orange peel.

    4.HL988 doesn't contain any silicone conponent. It won't affect the recoating adhesiveness.

  • Matt Hardener HC68
    Matt Hardener HC68 is a composed salt of cyclic-amidine and multi-acid. It utilizes the two different reaction rates of group in molecular structure, and during the curing process, it generates nonuniform shrinkage then forms the matt surface....

  • 1. HC68 can be applied in epoxy powder system to generate the strong matte effect, terrific levelling performance and stable comprehensive properties. It can be used for pure epoxy and epoxy/polyester hybrid powder systems as a hardener, preparing coating with super matte surface, excellent mechanical property and good reproducibility characteristic.

    2. HC68 has both gloss decreasing and curing functions.
