Ⅲ. Applications
- Used as a tackifier for silicone pressure-sensitive adhesive;
- Used as a reinforcing additive in silicone rubber to improve its mechanical strength with little impact on transparency;
- Used in cosmetics as a surface protective film to enhance gloss and scratch resistance, while eliminating the greasy feel of silicone oil and enhancing the slipperiness;
- Used in release agents to improve releasing efficiency and durability;
- Used in defomers to improve temperature resistance, alkali resistance, and foam suppression performance.
Ⅳ. Packaging and Storage
Packed in 200kg plastic-lined iron drums (P-series packed in 25kg fiber drums). Store at room temperature (0~35℃) in unopened packaging without exposure to direct sunlight. The shelf life is 6 months for S series, and a year for P and N series. P and N series are classified as non-hazardous, while the S series must be stored and transported as hazardous goods.
