Description: It is a composed salt of cyclic-amidine and multi-acid, equivalent to B68 of HUELS AG company Germanic. RB68 is a low-gloss curing agent making the film much lower gloss, with high mechanical strength and fine appearance. Appearance: White powder Purity: Larger than 98% Melting range: 200 to 225 (celsiur scale) Solidified condition: In 20 to 25 minutes at 180 cesiur scale, in 10 to 15 minutes at 190 cesiur scale, and in 10 to 12 minutes at 200cesiur scale. Application: Epoxy-resin powder or compound epoxy/polyester-resin powder. The force-out temperature should be properly increased in order that the curing agent can be well distributed in dissolution, as it has a higher melting point leading to unsatisfied blend with resin. In the course of applying to low-gloss compound powder, a lower acid value of polyester resin can be ed to get the required gloss and the best comprehensive performance. Package: 20kgs/Polyethylene kraft bag. Storage: In a sealed chamber and carefully resealed after use, and valid for twelve months.
