Matt Hardener SL628
 

Description: Matt Hardener SL628 is made for outdoor powder coatings. It has good weather durability, and can be applied in TGIC/polymer system or other similar curing systems. Coatings formulated with SL628 can produce a gloss range from 8% to 40% @ 60 angle with good flow.

Technical data:

Use level

90-110 PHR (based on unreacted epoxy compound)

Appearance

Pale yellow powder

Curing condition

190¡æ/15min; 200¡æ/12min

Application:

In the formulation, the ratio of TGIC to polyester should be unbalanced to provide excess TGIC for reaction with SL628.

Polyester to react with TGIC may be divided into 3 ratios/type viz. 96:4 (AV: 20), 93/7 (AV: 35) and 90/10 (AV: 50). In low gloss coating based on SL628, we recommend either the 96/4 or 93/7 ratio.

The dosage of SL628 in the range of 90-110 PHR is based on the excess TGIC. Benzoin or hydrogenated caster oil could be used to degas the film and improve the flow.
