The present invention relates to an anaerobically curable impregnation sealant composition and methods thereof containing a (meth)acrylic monofunctional monomer with a hydrophobic moiety, a (meth)acrylic monofunctional monomer with a hydroxyl group, a modified polyester urethane methacrylate resin having a weight average molecular weight of from about 8000 to about 18000 g/mol, and triallylisocyanurate, triallylcyanurate, or derivatives thereof, or a combination thereof. The present invention particularly relates to a sealant composition for impregnation to plastic and metal substrates that also provides resistance to thermal cycling.

The present invention aims to provide a curable resin composition that can reduce the occurrence of voids and partial detachment between the composition and a support even in high-temperature processing at 300° C. or higher with an adherend fixed to the support with the composition, and is easily separable after the high-temperature processing. The present invention also aims to provide a temporary fixing material including an adhesive layer containing the curable resin composition and a method of producing an electronic component using the temporary fixing material. Provided is a curable resin composition containing: a maleimide group-containing reactive compound (1); and a resin (2) having an imide skeleton in a backbone repeating unit.

The present invention provides a reaction mixture comprising a blend of a first isocyanate-based uretdione-containing resin and a second isocyanate-based uretdione-containing resin, a neutralized polyol and a tertiary amine catalyst, and optionally, an additive package selected from the group consisting of flow control additives, pigments (colorants), wetting agents, and solvents, wherein the first isocyanate and the second isocyanate are different. The first isocyanate-based uretdione-containing resin and the second isocyanate-based uretdione-containing resin may be cold blended or hot blended. Coatings, adhesives, castings, composites, and sealants made from hot blended formulations exhibit superior performance over those made from cold blended formulations.
