1. Product Features
One-component room temperature curing silicone rubber, dealcohol curing, odorless after complete curing;
Excellent adhesion performance, with good adhesion to most materials (to glass, aluminum, ceramics, ABS, PBT, PET, PVC and PC), generally do not use primer;
High and low temperature resistance is excellent, and the performance changes little in the range of -50℃~+180℃;
Low organic volatile content
This product complies with Reach, RoHS, sulfur-free, halogen-free, UL and other directives.
2. Main use
Bonding and sealing of lamps such as energy-saving lamps, automobile lamps and other products;
Structural bonding and sealing of various glass, aluminum and engineering plastics;
Various uses in other industries where bonding or sealing is required.
Designed for bonding applications that require high strength and flexibility, such as where the thermal expansion coefficients of the materials being bonded are inconsistent, such as glass-to-metal and glass-to-plastic bonding.

4. Instructions for use
1. The construction environment of sealant should be constructed in a clean environment with a relative humidity of 40% to 80%;
2. In order not to affect the bonding effect, it is recommended to degrease and decontaminate all surfaces, and ensure that they are clean and dry. Suitable solvents include isopropanol, acetone or methyl ethyl ketone.
3. Apply this sealant to the already pre-treated surface, then quickly cover the other side that needs to be glued.
4. When exposed to moisture, the sealant will skin within 10 to 15 minutes at room temperature and 50% relative humidity. Use a knife to scrape off the excess sealant before the surface is skinned, and the cured surface can be easily hung up with a scraper.
