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.

A liquid crystal display device of the present invention includes a thin-film transistor substrate, a counter substrate facing the thin-film transistor substrate, a liquid crystal layer provided between the thin-film transistor substrate and the counter substrate, an alignment film provided on the thin-film transistor substrate; a sealing material which bonds together the thin-film transistor substrate and the counter substrate at the periphery of the liquid crystal layer, and a polymerized layer provided on the liquid crystal layer-side surface of the alignment film. The alignment film contains a first polymer and a second polymer of a different type from that of the first polymer and is chemically bonded to the sealing material, the first polymer and the second polymer contained in the alignment film are mixed in a surface layer in contact with the liquid crystal layer, and the first polymer and the second polymer have different photo-functional groups.

An acrylic rubber contains a copolymer of a monomer mixture of: 25 to 46 wt. % of alkoxyalkyl acrylate, 23 to 37 wt. % of 2-ethylhexyl acrylate, 9 to 17 wt. % of alkyl methacrylate, 1 to 3 wt. % of monoalkyl fumarate and the remaining amount is ethyl acrylate. This acrylic rubber improves hydrolysis resistance by introducing a specific alkyl acrylic monomer with extremely low hydrolysis property i.e. low hydrophilicity, and at the same time satisfies all of oil resistance, cold resistance, and hydrolysis resistance in a well-balanced manner.

A composition for sealing joints, penetrations and other leaks in particular in the construction field, including at least one ethylenically unsaturated, radically polymerizable water-soluble compound, at least one radical initiator, water and at least one corrosion inhibitor including at least one phosphate. The corresponding composition has a corrosion-inhibiting effect with respect to metal.

Phenylhydrazine/anhydride adducts and anaerobic curable compositions using these adducts are provided. The compositions are particularly useful as adhesives and sealants.

A resin composition for sealing an electronic control device, which contains (A) at least one type of thermosetting resin selected from among an unsaturated polyester resin and a vinyl ester resin, (B) a polymerizable unsaturated compound, (C) an inorganic filler, (D) glass fibers, (E) an internal mold release agent, (F) a coupling agent, and (G) a curing agent, and in which, relative to a total of 100 parts by mass of the thermosetting resin (A) and the polymerizable unsaturated compound (B), the content of the inorganic filler (C) is 150 to 700 parts by mass, the content of the glass fibers (D) is 0.1 to 60 parts by mass, and the content of the coupling agent (F) is 1.4 to 20 parts by mass.

A wide temperature water borne sealant that can be applied at low temperatures. The sealant can be a latex sealant composition including at least one latex polymer, at least one freeze thaw stabilizer, and at least one peptone or at least one additive derived from a peptone. The latex polymer can be an acrylic latex polymer with a Glass Transition Temperature (Tg) of 0 C. or less. The peptone can be enzymatic hydrolysate. The sealant can remain pliable at low temperatures making it ideal for applications that require flexibility at low temperatures its' rheology and viscosity are such that it can be applied at temperatures below 0 C. The low Tg latex assures that the sealant will remain permanently flexible and non-tacky when cured, and the peptone provides the sealant with the means to prevent the water from freezing down to approximately 20 C.
