SA2061B Matting agent for polyester powder coatings

Matting agent is an additive added to powder coating formulations to reduce the gloss of the coating film. It creates a rough microscopic coating surface through the compatibility difference between the matting agent and other base materials.Klarint® is a profession additive in China for powder coating whose Matting Agent Series is developed for various powder coating systems, and widely used by lots international famous powder coating factories.

1. Description:

Klarint® SA2061B is an economic matting agent characterized by suitable PES/TGIC powder coatings, obtained by dry blending way to provide gloss ranges from about 10-40%(60°) gloss.

2. Typical properties:

Appearance free flow, pale yellow powder [visual]

Soft point (C) 135- 155 [Ring & Ball method]

Volatiles (%) ≤ 1.0 [GB 1725]

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

3. Characteristics:

Apply to exterior durable PES/TGIC powder coating obtained by dry blending way to provide acceptable flow and ranges of from about 10-40%(60°) of low gloss depending on the used polyesters. In general, selecting slow curing polyesters are favorable.
The coating surface performance is depending on base coating powder as well as process control, such as appropriate powder particle size distribution. In most cases, as same as most of dual components of dry blending powders, film surface exhibits micro-roughness and bright spot.
Satisfy to formulate low use level and low cost powder coating of requirement.
Good mechanical properties and color/gloss stability.
