How to remove silicone adhesive sealant?
Before the silica gel is solidified: scrape off the uncured paste with a putty knife, and then clean the residue with petroleum ether (120 # gasoline). After the silica gel is solidified: first, use a knife or razor to mechanically scrape as much silica g

How to improve curing speed of silicone adhesive sealant
When the curing thickness is greater than 6mm, it is recommended to apply the glue twice; Increasing temperature and humidity can accelerate the curing speed of the product, but the temperature should not exceed 50 ℃. Increasing humidity is better than

How does the "aerosol" phenomenon of ketone oxime silica gel occur in a closed system?
When the ketone oxime silica gel is used in closed systems, such as lighting, lamps and other industries, it sometimes produces a phenomenon similar to "fog" on the inner surface of the glass, which greatly reduces the transparency of the glass

Why is the viscosity difference of silicone adhesive sealant in winter and summer?
The viscosity of the glue will change with the temperature, and the high viscosity of the temperature in summer will decrease, while in winter it is just the opposite, but it will be within the acceptable range.

Why is white silicone adhesive sealant prone to yellowing?
The ketoxime cross-linking agent, amino silane tackifier and catalyst contained in the de ketoxime type silica gel may be yellowed on the surface due to the oxidation of amino groups or some chemical reactions of the catalyst under long-term ultraviolet l

Why is the surface drying time of silicone adhesive sealant different in winter and summer
The surface drying and curing speed of one component condensation curing silicone rubber products have a great relationship with the ambient temperature. In winter, the humidity and temperature are low, the glue surface is dry and the curing speed is slow

How can one component silicone adhesive sealant achieve curing performance?
One component condensation curing silicone rubber products are cured by using moisture in the air. When curing from the outside to the inside, the single component adhesive sealant can be cured for 3mm within 24h at 25 ℃ and 50% RH; It usually takes 7 d
