Solid Acrylic Acid Resin Polymer (9003-01-4)

These Solid Acrylic Acid Resin Polymer (9003-01-4) is a solid GMA acrylic resin capable of reacting carboxyl polyester to provide exterior durable powder coating with low gloss.
Typical properties
Appearance [visual] Granules
Soft point (C) [Ring & Ball method] 115-130
Epoxy equivalent weight [EEW] 530-630
Volatiles (%) < 1.5

Application
RDE500 can be mixed with various carboxyl functional polyester resins to formulate matte, one shot, and exterior durable polyester powder coatings with ranging from about 5 to 30% of low gloss.

Process & Mixing ratio
Added to formulation in pre-mixing stage, then extrusion; Mixing ratio RDE500/polyester [AV. Ca. 34mgKOH/g] = 25-30/75 by weight parts.

Co-reactants & Catalysts
The gloss can be adjusted to range of 25% and more with TGIC, HAA [hydroxyalkylamide] or RDE300 in replace of part of RDE500. In addition, some cure catalysts may improve coating mechanical/surface performance.

Shelf life
Based on our experience the shelf life of this product is at least within one year from date of manufacture. For older than this period, it is recommended to check the epoxy value.

Storage & Notice
Store in temperature between 2 and 35 C or cool dry place to avoid wetting-absorption.

Handing & Precaution
Avoid contact with eyes and skin. Avoid breathing dust. Wash after handling.
