Process for providing a binder for mineral fibers, comprising the steps of: mixing together under reactive conditions an amine and an anhydride whereby water is added thereto, once substantially all the anhydride is dissolved and / or reacted in the amine.

The curing rate of a two component laminating adhesive is effectively accelerated by incorporating in at least one component a microencapsulated catalyst. When the laminating adhesive is subjected to an effective amount of pressure (for example, the pressure applied when laminating flexible films together using nip rollers), the catalyst (which may be, for example, a dialkyl tin dicarboxylate) is released from encapsulation and is made available to catalyze the polyurethane-forming reaction between the isocyanate groups and the active hydrogen-functionalized groups in the adhesive mixture.

The invention discloses acrylic resin paint capable of being quickly cured. The paint is a double-component curing system. Modified acrylic resin and alpha-(methyl)alkyl cyanoacrylate have good intersolubility and good adhesion, alpha-(methyl)alkyl cyanoacrylate can accelerate curing of a coating. The paint system can be quickly cured, and the environment-friendly coating which is good in weather resistance and high in adhesion can be obtained. The technology is simple, operation is easy, coating efficiency can be improved, and the good paint can be used for solar cell backplanes.

The curable casting compound comprises an epoxy resin having at least one aminoglycidyl group in the molecule, a curative, and a fluorosurfactant. In the manufacture of products based on this casting compound, the shaping and curing operation can be shortened considerably.

The invention discloses an all-solid low-energy-curing matte UV (ultraviolet) coating for a PVC (polyvinyl chloride) plastic and a preparation method for the UV coating. The coating contains the following components: 25-30% of special modified acrylic resin, 5-10% of urethane acrylate, 20-25% of high-functionality active monomers, 20-25% of a reactive diluent, 2-5% of a photoinitiator 1, 1-4% of a photoinitiator 2, 3-6% of a photoinitiator 3, 0.3-1.0% of a dispersant, 5-10% of extinction powder, 0.5-1.0% of wax powder, 0.1-0.5% of a defoamer and 0.1-0.5% of a leveling agent. The UV coating does not contain a solvent and can be cured to form a low-luster, high-scratch-resistant and pollution-resistant paint film only by 150-200 mj / m<2> of UV energy; and the UV coating is applied to soft PVC and can enable a base material not to be thermally damaged in a curing process, so that the application range of the UV coating is greatly expanded.

A radiation-curable fiber optic coating composition for an inner primary coating includes a coloring agent, preferably a dye or a dye precursor, compatible with the fiber of the fiber optic and capable of imparting a pre-selected color to the inner primary coating, or another coating. The coloring agent can be a reactive dye. Any of the dyes preferably is stabilized by a stabilizer in the colored coating layer, or, preferably, in a more exterior layer.

A fast curing composition that comprises a polymeric resin, a conductive filler and one or more near-infrared absorbing additives and optionally an oxygen scavenger or corrosion inhibitor or both, and other additives such as reactive or nonreactive diluents, inert fillers, and adhesion promoters. The composition may be conductive, resistive or anisotropically conductive. In another embodiment, this invention is a method for improving the cure speed of a composition by exposing the composition to a near infrared energy source.

The invention provides a colored film substrate and a manufacturing method thereof, a display panel and a manufacturing method thereof and a display device. The colored film substrate comprises a body and a catalyst thin-film layer pattern; the catalyst thin-film layer pattern formed on the body is used for forming a frame glue area; the catalyst thin-film layer pattern suitably allows frame glue to solidify faster after exposure to ultraviolet light. The colored film substrate has the advantages that the frame glue can solidify faster and more uniformly during solidifying.
