摘要:
Disclosed herein are an insulating layer composition for a substrate, including a soluble type liquid crystal thermosetting oligomer, a metal alkoxide compound, and graphene oxide, and an insulating film and a substrate using the same.The insulating layer composition according to the present invention can effectively lower a coefficient of thermal expansion thereof, and thus, a dimensional change due to heat can be minimized when the insulating layer composition is used as an insulation material of the substrate, resulting in a substrate having improved thermal stability.
摘要:
The present invention provides curable compositions comprising non-Sn organo-metal catalysts that accelerate the condensation curing of moisture curable silicones/non-silicones. In particular, the present invention provides Mn(III) complexes that are particularly suitable as replacements for organotin for sealant and RTV formulations. The Mn(III) complexes are comparable or superior to organotin such as DBTDL, superior to Mn(II) compounds, and exhibit certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the present compositions and provide good adhesion and storage stability.
