Abstract: High solids thermosetting elastomeric coating compositions are disclosed. The resinous binder of the coating compositions is based on a hard polyester polyol containing cyclic moieties plasticized with a soft polyurethane polyol and cured with a curing agent capable of reacting with active hydrogens, for example, an aminoplast curing agent. The coating compositions are particularly useful on elastomeric substrates such as high density polyurethane foams, as well as on metal substrates such as steel and aluminum.

Abstract: Cured coatings having a high degree of extensibility, gloss retention, good sprayability and other desirable properties are obtained from compositions comprising (A) an interpolymer of a hydroxyalkyl ester of an ethylenically-unsaturated carboxylic acid and a copolymerizable material; (B) an organic polyisocyanate; (C) a polymeric polyol of low glass transition temperature; and (D) a curing agent, present either externally and/or as a part of the interpolymer. These compositions, when used as coatings, are durable, adherent and highly extensible. The coatings are particularly useful on resilient and rubbery substrates such as EPDM rubber, foam rubber, polyurethane foam and vinyl foam and on soft metal surfaces such as steel and aluminum.

Abstract: Coating compositions having a high degree of elasticity, as well as toughness, durability and good metallic pigment pattern control are disclosed. This combination of properties makes the coatings particularly desirable for use on elastomeric substrates such as those associated with automobiles. The coating compositions comprise as a resinous component, an ungelled hydroxyl-containing polyester of high weight average molecular weight. The polyesters can be cured with a curative such as an aminoplast to give coatings having outstanding elastomeric properties and good pigment dispersibility, particularly good metallic pigment pattern control, properties not normally associated with polyesters for use in coating applications.

Abstract: Thermosetting resins containing hydroxyl groups which can be cured with aminoplast resins are stabilized by the addition of 1,4-diazo[2,2,2]-bicyclooctane. This method is particularly useful in stabilizing the gloss retention of extensible coatings formed by curing a hydroxyl-containing urethane product with an aminoplast resin. Such coatings can be applied to virtually any solid substrate and are especially useful on rubbery, resilient substrates such as polyurethane or polyethylene foam, natural or synthetic rubber or rubber foam, and various elastomeric plastic materials. They are also particularly useful on other substrates such as mild steel or aluminum.

Abstract: Polyurethane coating compositions having improved application characteristics as well as other desirable properties are prepared by adding insoluble crosslinked acrylic polymer microparticles to solutions comprising an ungelled hydroxyl-containing urethane reaction product. The compositions may be spray coated onto various substrates in two coat applications to form coatings having improved film build, pattern control and flow control while maintaining the gloss characteristics of the film. These coatings are useful in general coating applications and are particularly useful on resilient and rubbery substrates such as foams or extruded rubber.

Abstract: Thermoplastic coatings have a high degree of extensibility, gloss retention, good sprayability and other desirable properties are obtained from ungelled, storage-stable compositions comprising the reaction product of (A) an interpolymer of a hydroxyalkyl ester of an ethylenically unsaturated carboxylic acid and a copolymerizable compound, (B) an organic polyisocyanate, and (C) a polymeric polyol of low glass transition temperature. Rather than using the interpolymer itself, it is also possible to form useful products by reacting (B) and (C) with a hydroxyalkyl ester monomer in combustion with another copolymerizable monomer. These compositions when used as coatings are adherent, durable and highly extensible. The coatings are particularly useful on resilient and rubbery substrates such as foam rubber, polyurethane foams and vinyl foam and on metal surfaces such as mild steel and aluminum.
