Ⅲ. Features and Applications
This product is a low molecular weight, silanol-terminated polydimethylsiloxane, an oligomeric siloxane produced through the telomerization of cyclic siloxanes. It serves as a structural control agent in silicone rubber production, and as a chain extender for other products. Additionally, it can be used for water repellency, softening, and anti-adhesion treatments of fabrics, paper and leather, or as an additive in cosmetics.
Ⅳ. Packaging and Storage
- Packaging: This product is sealed in a clean and dry inner plastic-coated iron drums or plastic drums.
- Transportation: During transportation, exposure to sunlight and rain should be prevented. Transport it as non-hazardous goods.
- Storage: Store in a well-ventilated cool and dry place with no contact with harmful substances such as acid and alkali. The shelf life is 6 months, beyond which, re-test the product according to specifications. It may remain usable if it still meets the requirements.
