摘要:
This invention relates to urethane compositions comprising: (A) 100 weight parts of at least one compound containing at least one isocyanate group; (B) 0.3-300 weight parts of a carbinol-functional silicone resin; (C) up to 250 weight parts of an organic polyol; and (D) up to 10 weight parts of a cure rate modifier. The urethane compositions of this invention are useful as a stand-alone coating or as ingredients in protective coatings, paint formulations, and powder coatings. The urethane compositions of this invention can also be formulated with a blowing agent and cell stabilizer to produce thermally stable foam formulations.
摘要:
This invention relates to carbinol-functional silicone resins and a method to manufacture carbinol-functional silicone resins. This invention also relates to emulsion compositions comprising the carbinol-functional silicone resins. The carbinol-functional silicone resins can be used to make tough, water resistant, solvent resistant, scratch resistant, and heat resistant materials by formulating and reacting these silicone resins with certain organic materials.
摘要:
This invention relates to new blocked isocyanate silicone resins which can be used to make shelf stable one part curable coating compositions. These coatings do not cure until heated. The coatings provide weather resistant protection for numerous substrates including automobile exteriors, leather fabric, electronic components, wood floors and surfaces.

摘要:
The present disclosure provides hydrosilylation curable compositions comprising resin linear organosiloxane block copolymers comprising, among other things, from about 0.5 to about 5 mole % C1 to C30 hydrocarbyl group comprising at least one aliphatic unsaturated bond. Such hydrosilylation curable resin-linear organosiloxane block copolymers have significantly faster cure speed, relative to their condensation curable counterparts. A faster cure speed can be important for encapsulating electronic devices, such as light-emitting diode (LED) chip devices, particularly devices having tall structures.
