Laminates for printed wiring boards for the making of laminates for printed wiring boards having an impregnant including an epoxy resin, a first cross-linking agent of a strene-maleic anhydride copolymer and a second co-cross-linking agent.

Copolymer of styrene and maleic anhydride comprising an epoxy resin composition and a co-cross-linking agent

A composition useful as an impregnant for the making of laminates for printed wiring boards including an epoxy resin, a first cross-linking agent of a strene-maleic anhydride copolymer and a second co-cross-linking agent.

Epoxy resin, styrene-maleic anhydride copolymer and crosslinking agent

A composition useful as an impregnant for the making of laminates for printed wiring boards comprises a FR4 epoxy resin which is a bisphenol A epoxy resin advanced with tetrabromobisphenol A, a crosslinking agent of a strene-maleic anhydride copolymer and a co-crosslinking agent is an optionally brominated bisphenol A and/or an optionally brominated bisphenol A diglycidyl ether.

Laminate made from epoxy resin, styrene-maleic anhydride copolymer and crosslinkers

A water-vapor-permeable, watertight, heat-reflecting flat composite is made by a process of combining a metal layer and a nonporous, water-vapor-permeable, watertight, hydrophilic flat substrate. The process includes at least the three steps of (1) selecting the substrate, (2) pre-cleaning the substrate, and (3) applying the substrate to the metal layer. Such a composite offers protection from heat loss, infrared-based detection, ultraviolet radiation, electro-smog, and static electricity.
