KT207E hybrid matting agent for powder coating

KT207E is a new type of anti yellowing matting agent, mainly used in the hybrid system, due to the special design principle (a little excess epoxy but will be completely, it is not only the reaction) yellowing and can obtain the extinction effect is very low, mechanical performance is also very good. The extinction system is involved in the reaction of the whole system. Therefore, the powder prepared by K207E has good storage stability and high hardness of the surface of the coating, and the extinction effect can be obtained at least 4 degrees in the black system.
Two. Technical parameters
Appearance light yellow fine powder
Melting process NA
The volatile is less than or equal to 1.5%
Three. Application description
Can use 50/50 or 60/40 hybrid system, KT207E only need to add to the whole formula can be mixed extrusion, the amount of powder is generally 1% to 5% of the total.
The use of KT207E requires a moderate amount of epoxy resin, generally add one KT207E each additional 1.3 to 1.4 pieces of epoxy resin.
K207E can achieve 170 degrees above curing, but the luster will be increased, at the same time, the use of KT207E powder and the existing products of resistance to repeated extrusion Ketai basically does not affect the luster.
Curing conditions: 180---200 /15-12min.
Four. Storage and packaging
Polyethylene Lined kraft paper packing, net weight 25kg, stored in a cool and dry place
