Abstract:
Thermosetting powder coatings comprising reactive polymers containing reactive carboxyl, hydroxyl, and/or amide groups and adapted to be cross-linked with aminoplast resins are substantially improved by the inclusion of at least about 0.25% by weight of a heat curing catalyst. The catalyst is an amine salt of cyclohexyl sulfamic acid.

[Also in Divisions B2, B5 and C3] Thermoplastic resins (including thermoplastic cellulose derivatives) are bonded to siliceous materials, such as glass sheets or fabrics, asbestos, ceramics, or silicone elastomers, or to metals such as aluminium or steel, or metal oxides, by bringing the components together after having rendered the surface of one of them plastic, as by heating or applying a solvent, and after applying to one component a polymeric organo-silicon material having per molecule at least one silyl group at least one silicon atom being attached to oxygen, a hydrolysable group, a hydroxyl group or a hydrocarbon or halohydrocarbon radical of less than 10C atoms, the polymer having a molecular weight of at least 2000, preferably 10-20000, and containing at least three siliconbonded non-halogen hydrolysable or hydroxyl groups per molecule, the polymeric material being a graft polymer of the organo-silicon group with the, or a, thermoplastic resin or polyurethane, and being applied as such, or in a volatile solvent, or in aqueous solution or emulsion. The themoplastic component may be applied as a preformed layer, as an impregnant for a fabric layer or in solution as a coating. In a modification the polymeric organo-silicon material, in solution together with the thermoplastic resin, may be admixed with the siliceous component, e.g. chopped glass fibre, to form a moulding composition Examples of thermoplastic resins usable are polythene, polypropylene, polybutylene, polyisobutylene, polystyrene, p.v.c., polyvinylidene, chloride, P.T.F.E., polytrifluoropropene, polyvinyl acetate or acrylonitrile, polyacrylates and methacrylates, polyethyleneterephthalate, poly- 1,4-butane diol isophthalate, polyamides, polycarbonates, and polyformaldehyde; cellulose acetate and ethyl cellulose are included. The silicon-bonded hydrolysable groups in the polymeric organo-silicon material may be any groups replaceable by water to form Si-OH groups, e.g. alkoxy, acyloxy, or cyano or isocyano groups. Reference is made to the bonding by the method of the invention, of porcelain teeth to thermoplastic dentures and of a liner of room temperature-vulcanizing silicon elastomer to the surface of such dentures.
