Properties of polymethylsiloxane resin
Hits: 75
img
> Higher hardness
> Low thermoplasticity
> Poor compatibility with pigments
> It has good compatibility with inorganic products and mineral materials
> Limited compatibility with organic compounds
> Good early water resistance even when only partially cured
> It has hydrophobicity after crosslinking
Except for methyl groups, methyl-phenyl organosilicone resins usually contain more than 20% phenyl. The phenyl groups in these resins increase the long-term heat resistance of the resins to 200 ~ 250β. In addition, the addition of inorganic pigments may also increase the heat resistance (formula dependent) to 650 β.
