摘要:
Amino resins, e.g., urea-formaldehyde and melamine-formaldehyde thermosetting resins, are cured with a latent catalyst which is a thermally-decomposable adduct of an aromatic sulfonic acid (e.g., p-toluene sulfonic acid) and a bicyclic oxazolidines (e.g., 1-aza-3,7-dioxa-5-ethylbicyclo (3.3.0) octane. The coating compositions can contain other conventional co-reactants, such as polyols, polyacids, alkyd resins, polyester resins, epoxies, acrylics and the like. Coatings containing the amino resin, co-reactant, and latent catalyst have an acceptable viscosity stability, cure rapidly at temperatures lower than some other latent catalysts, and produce films with no wrinkles.
摘要:
A durable press resin composition comprising (1) an aminoplast resin, (2) an aldehyde, and (3) a diluent. The durable press resin composition is combined with an acid catalyst and applied to textile materials to impart softness, improved wetting properties and durable press properties. The durable press resin composition is applied at lower than normal dry add-on levels to textile materials to provide textile materials having lower levels of formaldehyde.
