K7227 Matting agent for hybrid powder coatings

1. Description:

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.

K7227is a wax-free, non-reactive and synthetic resin based matting agent designed for hybrid powder coating to provide 3-40%(60°) of gloss. It features suitable to standard curing condition, excellent flow/fineness surface, and outstanding gloss stability after re-extruded operation.

2. Typical properties:

Appearance                      White to pale yellow powder     [visual]

Solid content%                             ≥98.0                            [GB1725]

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

3. Characteristics:

• Excellent flow.& matt effect.

• Good mechanical property.

• Good stability for wide baking conditio.

• Wide range of applicability to polyester resins.

• Good anti-yellowing property.

4. Type specification:

5. Application:

6. Use method & levels

• Premix K7227 with other components of the formula before extrusion.

• The use level is 1-4.5% by weight based on total formula,depends on the gloss required.

7. Package & Storage

• Packaging with PE lined Kraft paper bag. Net weight 25kg per bag.

• Store in temperature between 2-32℃ or cool dry place. Keep away from heat and fire.

• Based on our experience the shelf life of this product under above conditions is at least 2 years.

8. Advisement:

Choose proper accelerator or catalyst to improve the impact resistance, but this will result in unexpected gloss up or worsen the surface leveling.
