Powder Coating Active Imidazole Catalyst

Model NO.: TP3127 Classification: Chemical Additives Appearance: Powder Trademark: t&p Origin: China Efficacy: Decrease Curing Temprature Type: Catalyst Color: White Specification: active content: 48%~52% GENERAL DESCRIPTION
TP 3127 is a 50% active imidazole catalyst specifically developed to facilitate dispersion and avoid hot spots of the catalyst during powder manufacture.  The additive is used to accelerate the cure of powder coatings based on the carboxyl-epoxy reaction, or for pure epoxy systems as well.  Typical systems include hybrids such as polyester-epoxy, carboxyl acrylic-epoxy and polyesters cured by GMA-functional acrylics.  Polyester-TGIC and polyester-PT-910 reactions can also be accelerated.  TP 3127 can reduce the cure temperature of a particular system or shorten the required bake time at a given cure temperature without sacrificing DOI or flow and leveling properties.  The product may also reduce star cracking on impact.
 
Due to the special composition of TP 3127, it is believed that this product provides some charging characteristics for tribo powder coatings.  The reaction response of TP 3127 is similar to propyl imidazole based products, but slower in rate and less yellowing than 2-methyl imidazole based catalysts.  Recommended usage level of TP 3127 is 0.3 - 0.6% on total formula weight.   Each application should be tested to determine the optimum catalyst level to achieve the desired cure time and coating properties.  More detailed applications information is described in the TP 3127 Technical Brief #1.   The active ingredient of TP 3127 is also available in pure form designated as TP110.
