LR-MQ Powder Methyl MQ Silicone Resin
Silfluo LR-MQ is a solid methyl MQ silicone resin produced by co-hydrolysis of tetraalkoxysilane (Q units) and trimethyl-functional silanes (M units), forming a three-dimensional trimethylsilane-terminated polysilicate network with M/Q ratio of 0.60–0.80. Supplied as a free-flowing spherical white powder with average particle size of 100 µm and bulk density of 0.25 g/cm³, the resin contains only trace aliphatic hydrocarbons and ≤0.5% hydroxyl content.
Uniform particle size and low fine-dust content provide consistent flow behavior during weighing and compounding. The low hydroxyl content (≤0.5%) reduces the risk of condensation side reactions in moisture-sensitive addition-cure systems and defoamer formulations.
LR-MQ is also available in toluene solution and silicone oil dispersion delivery forms for applications where powder incorporation is not practical.
