4. Product Usage Method
Clean the surface of the adhesive substrate first, then directly extrude or coat the product to the bonding area, and then heat to cure.
5. Precautions
1. The actual curing time is greatly related to the curing temperature, the type and efficiency of heating, as well as the size, shape, and thermal conductivity of the device. Therefore, when actually using, first test according to the specific situation to determine the suitable curing temperature and time.
2. After taking the product out from low-temperature storage, it is recommended to place it at room temperature for 1-2 hours before use.
3. Before vulcanization of this product, it should avoid contact with unsaturated hydrocarbon plasticizers, residues of flux, and organic compounds containing amines, phosphorus, sulfur, sulfone, arsenic, organic tin, etc., otherwise it will cause the silicone rubber to vulcanize incompletely or not vulcanize at all. Therefore, it is recommended to first conduct compatibility tests between the silicone rubber and the substrate before using this product.
4. This product has not been tested or stated to be suitable for medical or medicinal use.
5. The data in this material is for reference only.
6. Cleaning
Unvulcanized silicone rubber can be cleaned with hydrocarbons such as toluene or 120# gasoline, while polar solvents such as ketones and alcohol compounds are not suitable choices.
7. Product Packaging
This product is available in two packaging specifications: barrel packaging and tube packaging.
8. Product Storage and Transportation
One-component liquid silicone rubber is non-hazardous and can be transported as non-hazardous goods.
Store sealed at 0℃-10℃, and the shelf life is 6 months.
9. Safety Instructions
The main components of liquid silicone rubber have been proven to be essentially harmless products after many years of application at home and abroad, and no special safety measures are required. Only general industrial safety and health regulations are required during use.
This material does not include the necessary product safety information, and the product instructions should be read before use. If you need the relevant safety data sheet, please contact us and request it.
