Typical physical data
Suggested formula
Characteristics
①T-600 and TGIC both can be used as curing agent with carboxyl polyester.
1.1 T-600 to polyester ratio is 1/2.5 when use polyester with acid value around 35 mgKOH/g.
1.2 T-600 to polyester ratio is 1/3.5 when use polyester with acid value around 25 mgKOH/g.
Normally select lower acid value polyester to get cost reduction and more smoothness film appearance.
②HAA curing agent,T-318/TGIC, usually is used to adjust the gloss of finish. In mass production, we always fix the usage of
pure polyester, T-600 and catalyst T-62, and only control gloss by T-318/TGIC or primid.
③Using 0.05～0.2% T-62 in formulations above can make film mechanical performance better, gloss lower and stable, with
reduced cost. But when use too much, levelling would be affected.
