NEW WATER-COATED SILICONE TECHNOLOGY FROM GRANT

摘要

The challenges of dispersing standard silicone elastomers in water are well known. Standard silicone elastomers can be very difficult to disperse uniformly in external water phase emulsions or aqueous gels due to their inability to fit into o/w micelles and general hydrophobic incompatibility with water. Often when processing, excessive levels of surfactants and high shear energy is required to disperse and maintain particles to a stable state. High concentrations of surfactants (which coat particles to maintain a dispersion) unfortunately reduce the elastomer sensory properties by creating tackiness. Surfactants are also more likely to cause some level of barrier disruption. According to Grant, the unique design of versatile Gransil SiW Elastomer Gels resolves these challenges.
