Herein described to be typical properties and do not constitute specification limits.
2. Characteristics
● Almost suitable for any 50/50 or 60/40 type hybrid polyester resins without remarkable selectivity, whether fast-curing or not.
● Can satisfy wide ranges of baking requirements to result in gloss-stable, excellent flow, and outstanding mechanical properties. The low temperature curing of 160℃/25min or 170℃/20min can be achieved depend on the particular fast-curing polyester used in formulation.
● Excellent overbaking stability.
● Eliminating effectively fingerprint on coating surface.
● The recoatability and transfer-image properties of coatings are not influenced.
3. Use method & levels
● Premix SA2165D with other components of the formula before extrusion.
● The use level is 1- 4.5% based on total formulation by weight,depends on the gloss required.
4. 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.
● From our experience,the shelf life of this product under above conditions is at least 2 years.
5. Advisement
● Choose proper accelerator or catalyst to improve the impact resistance, but this will result in unexpected gloss up or worsen the surface leveling.
