RF701

Parameters		Test Methods
Color (50% DMF Solution)	≤4	ASTM D 1544
Acid Value (mg KOH/g)	72—79	ASTM D 1613
Softening point (°C)	96—110	Ball and Ring
Vitrification Point (°C)	≈55	ASTM D 3418
ICI Viscosity (200°C Pa.S)	0.2—0.4	ASTM D 4287

Combined with epoxy resin (50:50), it can be processed into a compound powder coating with fine gloss, high mechanical strength and excellent decorative effect.

RF704 　

Parameters		Test Methods
Color (50% DMF Solution)	≤4	ASTM D 1544
Acid Value (mg KOH/g)	30-38	ASTM D 1613
Softening point (°C)	105-115	Ball and Ring
Vitrification Point (°C)	60-63	ASTM D 3418
ICI Viscosity (200°C Pa.S)	0.2—0.4	ASTM D 4287

Combined with TGIC, it can be processed into a pure-polyester type powder coating with more perfect balanced behavior, and no-caking by powder baking. And it may be also used outdoor.
