摘要:
This invention relates to a flame retardant composition comprising: (a) 81 to 99.99 weight percent of a thermoplastic resin, thermoset resin, thermoplastic resin blend, or thermoset resin blend which upon burning forms a char and (b) 0.01-19 weight percent of a silsesquioxane resin having a weight average molecular weight of greater than 300.
摘要:
A radiation or thermal curable coating composition contains a cycloaliphatic epoxide resin, a carbinol functional silicone resin or an anhydride functional silicone resin, and a thermal or photoactivated acid catalyst. An organic polyol may also be included in the composition as an optional component. The composition is useful as a radiation curable coating, as an adhesive, a photodefinable coating, or as a thermal cure coating. The cycloaliphatic epoxide resin adds toughness and adhesion to the composition, whereas either of the carbinol functional silicone resin or the anhydride functional silicone resin provides the composition with water resistance, weatherability, thermal stability, and flexibility.
摘要:
Thermal curable compositions contains a glycidyl ether epoxide resin, a carbinol functional silicone resin or an anhydride functional silicone resin, and a thermal catalyst. An organic polyol, an organic anhydride, and filler, are optional components that may also be included in the composition. The glycidyl ether epoxide resin adds toughness and adhesion to the composition, whereas the carbinol functional silicone resin and the anhydride functional silicone resin provide water resistance, weatherability, thermal stability, and flexibility.
摘要:
A coating composition, which may be a two-component coating composition, comprises a film-forming material, a crosslinking agent, and a nonlinear polysiloxane polymer having a functional group reactive with the crosslinking agent. The coating composition exhibits excellent scratch resistance and adhesion of repair coating layers and sealants, such as windshield sealants.

A coating composition, particularly a clearcoat composition, which may be a two-component clearcoat composition, comprises a film-forming material, a crosslinking agent, and a nonlinear polysiloxane polymer having a functional group reactive with the crosslinking agent. The coating composition exhibits excellent scratch resistance and adhesion of repair coating layers and sealants, such as windshield sealants.

Siloxane resin compositions obtained by mixing a MQ siloxane resin with a propyl silsesquioxane resin are disclosed. These siloxane resins are useful in a variety of personal, household, automotive and medical care applications, and in particular, as a resin additive in pigmented cosmetic formulations.
