SA300 Glycidyl functional acrylic resin for powder coatings

1. Description:

Acrylic resins are used as additives to promote improved flow and leveling as well as enhanced stain and chemical resistance in polyester hybrid, polyester TGIC, and polyurethane powder coatings. Unlike standard flow aids, these reactive materials provide improvements in film properties by crosslinking into the powder coating polymer backbone. 

SA300 is a glycidyl containing-solid acrylic resin capable reactive with carboxyl or amine compound, which is designed to be used in combination with other curing agents to provide powder coatings with higher crosslink density, improved mechanical properties, heat and chemical resistance.

2. Typical properties:

                                     Appearance                                   Pale yellow to white granule                  [visual]

       Soft point(C)                                         105-120                                          [Ring & Ball method]

    Epoxy equivalent weight                          290-330                                          [ASTM D1652]

Herein described to be typical properties and do not constitute specification limits.

3. Characteristics:

As co-reactant or accelerator, SA300 is recommended to use in such powder coating system based on crosslinkage chemistry of oxirane reactive with carboxyl compounds to provide

Higher crosslink density.

Improved mechanical properties.

Heat and chemical resistance and gloss adjustable.
