Methyl biphenyl room temperature vulcanized silicone rubber not only possesses excellent properties of methyl room temperature vulcanized silicone rubber, but also has a wider temperature range (-100~250 ℃) compared to methyl room temperature vulcanized silicone rubber. Low phenyl room temperature vulcanized silicone rubber (108-1) with a phenyl content of 2.5-5% can maintain elasticity under low temperature conditions of -120 ℃, making it currently the best variety of silicone rubber with low temperature performance; Room temperature adhesive (108-2) with a phenyl content of 10-20% has good radiation resistance, ablation resistance, and self extinguishing properties. If a certain amount of heat-resistant additives such as Fe2O3 are added to it, the thermal aging performance can be improved. It is suitable for use at high temperatures above 250 ℃ or as a corrosion-resistant putty coating and sealing material.
Methylphenyl room temperature adhesive, like other room temperature adhesives, can be used for impregnation, impression, and film removal. If you want to increase the adhesion with other materials, you must perform surface treatment on the adhered material before using it. The surface treatment steps are as follows: clean the surface of the material with acetone solvent 1-2 times, then treat it with a surface agent 1-2 times, and dry it in a 60 ℃ oven for a few minutes. At this time, a layer of less sticky film is formed on the surface of the material, and the adhesive can be applied.
