The structure of MQ silicone resin is as follows: the core is composed of SiO4/2 polymer (i.e. Q), and the periphery is capped by trimethylsiloxy groups (i.e. M), forming a tight double-layer ccage structure of silicone resin. It appears as white loose powder or flaky solid.
In addition to containing Si-OH groups, it can also contain other active groups. The MQ resin with all trimethyl ends on the periphery is methyl MQ silicone resin. When part of the methyl groups in methyl MQ silicone resin are replaced by Vi groups, it becomes methyl vinyl MQ silicone resin; when part of the methyl groups are replaced by Me2HSiO- groups, it becomes hydrogen-containing MQ silicone resin. Due to this special molecular structure, MQ silicone resin is easily soluble in organic solvents such as toluene and xylene. The solution is clear and colorless, and it has excellent mechanical properties, insulation, moisture-proof, water-proof and high and low temperature resistance.
