T-600

Description

T-600 is a epoxide group containing solid acrylic resin designed for applying in low acid value statured carboxyl polyester powder coatings system as hardener using compatibility difference to achieve matt gloss.The final Matt finish smooth and suitable for transparent finish.

Gloss 2~6% / Square impact 50kg/cm
Curing condition: 200℃×10min

Characteristics
- T-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
- HAA 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.
- Using 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.
