2. Characteristics
● Jietonda® SA2165 is almost suitable for any 50 to 50 or 60 to 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℃/20 min. can be achieved depend on the particular fast-curing polyester used in formulation.
● Excellent overbaking stability, △E≤1.8 at 200℃×1hrs.
● Eliminating effectively fingerprint on coating surface.
● The recoatability and transfer-image properties of coatings are not influenced.
3. Use method & levels
● Premix SA2165 with other components of the formula before extrusion.
● The use level is 1-5% based on total formula by weight,depends on the gloss required.
4. Package & Storage
● Packaging with PE lined Kraft paper bags. Net weight 25kg per bag.
● Store in temperature between 2 and 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.
5. Advisement
● Choose proper accelerator or catalyst to improve the impact resistance,but this will result in unexpected gloss up or worsen surface leveling.
