Application
1. Used as a base material for the production of high-temperature vulcanized silicone rubber (HTV), with cross-linking agent, reinforcing agent, colorant, structure control agent, aging resistance agent and other mixing to prepare high-temperature vulcanized silicone rubber raw rubber.
2. Used to make liquid silicone rubber, is the main material for injection thermoforming silicone rubber;
3. This product reacts with polyurethane, acrylic and other organic materials, and can be made into new materials with better performance (weather resistance, aging resistance, ultraviolet resistance, enhanced toughness, etc.) (such as coatings are important raw materials for the production of various coatings and modified silicone oil and other products. )
Use of terminal vinyl silicone oil:
This product is a double vinyl terminated polydimethylsiloxane, stable product quality, low volatile content, is the main raw material for molding liquid silicone rubber, silicone potting material, silicone gel, etc., and a modifier for mixed rubber.
Use of high vinyl silicone fluid:
This product is double vinyl terminated or methyl terminated and the intermediate link contains vinyl polydimethylsiloxane, stable product quality, low volatile content, no yellowing and no crosslinking. It is the main raw material for adding molding liquid silicone rubber, silicone potting material, silicone gel, etc.; modifiers for compounds; plastic additives, etc.
Usage and dosage
The dosage is 10%-20% when used as a diluent, the dosage is 5%-10% when used as a modifier, and the dosage is 50%-100% when used for silicone rubber base rubber. Join directly
Or add it to the system with the help of high-speed stirring or powerful stirring equipment to ensure uniform dispersion.
Notes
This product is a chemically active material, in the storage and transportation process should not be mixed with impurities (especially catalyst), in the use or matching, should pay attention to other materials can trigger its chemical reaction, to prevent denaturation.
Packaging and shipping
