Abstract:
A self-leveling finishing composition capable of providing chemically resistant low profile coatings is described. The finishing composition comprises thermoplastic resin solids and thermosetting resin solids in a weight ratio of about 0.5:1 to about 11:1 and a solvent composition comprising a solvent capable of dissolving the thermoplastic resin solids component and a solvent miscible co-solvent capable of dissolving the thermosetting resin solids. The finishing composition is applied and dried to a dry-to-touch surface which is thereafter subjected to conditions capable of initiating polymerization of the component thermosetting resin solids. The finishing composition can be used as a substitute for more expensive or more labor intensive coating compositions in existing surface finishing protocols without compromise of surface quality and chemical resistance.

Abstract:
A coating material contains at least one substance selected from the group consisting of water-soluble resin such as water-soluble acryl resin, resin emulsion such as acryl emulsion and solvent resin such as solution of urethane resin into a solvent (A); resin beads such as polyethylene beads (B); and at least one substance selected from the group consisting of soluble protein such as collagen and resin emulsion incompatible with the (A) such as ethylene-acryl copolymer (C). (A) improves adhesion with a base member, (B) improves heat sealability and (C) improves surface lubricity and anti-blocking properties. Further, water-soluble amine additive (D) may be added to improve adhesion with olefin base member.
Abstract:
This invention provides low foam waterborne polymer compositions stabilized against gelling due to the addition of a poly(alkyleneimine) by addition of surfactants. Preferably, the surfactants are nonionic surfactants having a hydrophilic-lipophilic balance (HLB) of at least about 17.5. Polymerization in the presence of phosphate surfactants has been found to yield low foam polymers. These stable low foam polymer compositions are useful in a variety of coating formulations such as, for example, paints, inks, sealants, textile backcoatings, adhesives and the like. Methods of making stable low foam polymer are also disclosed.

Abstract:
Previously cross-linked silicone elastomer particles with an organopolymer sheath are used as constituents for formulating water lacquer compositions based on water-soluble or water-dilutable binders. The silicone elastomer particles contain: (a) 5 to 95 % by weight, with respect to the total weight of the copolymer, of a nuclear polymer of general formula (R2SiO2/2)x.(RSiO3/2)y.(SiO4/2)z, in which x = 5 to 99.5 % by mole, y = 0.5 to 95 % by mole, z = 0 to 30 % by mole, and (b) 5 to 95 % by weight, with respect to the total weight of the copolymer, of a sheath made of an organopolymer from mono- or polyethylenically unsaturated monomers; and R stands for the same or different monovalent alkyl or alkenyl radicals with 1 to 6 C atoms, aryl radicals or substituted hydrocarbon radicals.
