摘要:
The present invention provides moisture curable polyacrylate compositions, which cured elastomers thereof demonstrate improved resistance to shrinkage when exposed to hydrocarbon fluids such as transmission fluids and oil and fuel based fluids. Such compositions include: a) a moisture curable silyl functionalized polyacrylate; and b) at least one hydrocarbon fluid-absorbing component, wherein the hydrocarbon-fluid absorbing component is present in an amount sufficient to reduce shrinkage of the cured composition when exposed to a hydrocarbon fluid.
摘要:
Heat-curable silicone compositions employing a reactive silicone, a silicone hydride crosslinker and a catalyst system which includes a rhodium-based catalyst, a stabilizing system are disclosed. A combination of rhodium and platinum-based catalysts are employed as well. The compositions are low temperature curing and are capable of providing low coefficient of thermal expansion compositions. A stabilizer system which includes in combination a peroxide and an acetylenic compound is also disclosed.

摘要:
This application relates to polysiloxane compositions grafted with improved heat curable, moisture curable, or heat/moisture curable groups. In particular, the polysiloxane compositions have reactive groups on the terminal or pendent areas of the siloxane backbone, which once reacted provide improved heat and/or moisture curable polysiloxanes.
