  • Patent number: 4343924
    Abstract: Disclosed is an improved method for coating a substrate with a film of a coating composition rapidly curable at room temperature in the presence of a vaporous tertiary-amine catalyst. The pot life of the coating composition is substantially increased without deleterious loss of properties of the ultimately cured film wherein the coating composition comprises three components. The first component is a phenol-functional condensation product of (a) a phenol-aldehyde reaction product bearing a plurality of methylol and phenol groups, and (b) a polyol, polycarboxylic acid, or polyepoxide, wherein the condensation product is reacted with a selective transmethylolating agent for substantially transforming residual methylol groups into non-active hydrogen groups. The second component is a multi-isocyanate cross-linking agent and the third component is an organic solvent. The coating composition is applied to a substrate and cured by exposure of the coated substrate to a vaporous tertiary amine catalyst.

  • Patent number: 4281089
    Abstract: Polyurethane prepolymers having free isocyanate groups are treated with polyfunctional isocyanate-blocking agents to cause branching prior to or simultaneously with the addition of a curing diol. The composition containing the curing diol is molded in a conventional equipment at a conventional temperature, e.g., 100.degree.-120.degree.C. The resulting shaped article can be demolded in a fraction of the time required in the absence of the blocking agent. The shaped article is then post-cured within a temperature range of about 25.degree.-150.degree. C., during which time the curing diol, if present in sufficient amount, displaces the blocking agent and forms a cured, linear polyurethane. A typical suitable blocking agent is a substantially uncrosslinked phenol/formaldehyde resin. The curable composition can be prepared in one step from the diisocyanate, glycol, and blocking agent; and a composition containing all the components, including the curing diol, can be prepared in one or more steps.
