Application and Usage

At room temperature, it can react with crosslinking agents in the presence of catalysts, to form a reaction product, which has many excellent properties such as keeping good elasticity from -60℃ to 200 ℃ , excellent electrical property chemical stability and good resistance to water, odor, weather. Therefore, it can be widely used in many industries, such as electronics, semiconductors, autos, mechanicals, fabric, plastic, printing, construction, etc.

Package, Storage and Handling

Storage at ventilate and dry place and prevention from water, heat and fire. Keep away from alkalis and acids substances and lead. It is non-hazardous substance. Be careful when loading and unloading to avoid damages of the package. During transporting, protect against damp, water, acid and alkali.

ECHEMI Editorial Reference

Polydimethylsiloxane, dihydroxy terminated is a non-toxic, optically transparent, inert, flammable silicone-based organic polymer. It is widely used in heat-resistant lubricants, flame retardants, medical devices, and cosmetics. Polydimethylsiloxane is hydrophobic, cytocompatible and viscoelastic and can be used for water-repellent coatings in the textile industry.
