  • Process for producing high gloss laminates using a vapor barrier at each end of a laminate assembly
    Patent number: 4599127
    Abstract: A laminate assembly, containing press plates having smooth polished sides and laminate stack-up sets, for producing high gloss laminates, is molded using a vapor impermeable barrier layer positioned between stack-ups in the stack-up set next to the exterior press plates, so that during the fast heatup of that stack-up set during molding, vapor travel toward the interior of the assembly is controlled, preventing vapor buildup, and low gloss areas on certain laminates.

  • Antistatic laminates containing metal salts
    Patent number: 4480001
    Abstract: A static-dissipating laminate is made, containing at least a bottom core layer and a top decorative layer, both layers containing fibrous material which is impregnated with a resin, where at least the decorative layer has a metal salt distributed through it in an amount effective to provide an antistatic effect to the laminate, so that static charges accumulating on the top of the decorative layer are dissipated.

  • Polyethylene glycol modified melamine aldehyde resin and postformable laminate made therewith
    Patent number: 4405690
    Abstract: A modified melamine resin, useful for impregnating surface sheets for postformable laminates, comprises: (A) melamine and aldehyde, where the mole ratio of melamine to aldehyde is from about 1 to 1.5 to about 1 to 3, (B) about 1 to 45 weight percent, based on weight of melamine, of water soluble polyethylene glycol having a molecular weight of from about 200 to about 1,000, and (C) water; where the polyethylene glycol, melamine and aldehyde are reacted together in the presence of heat and water.
