Abstract:
Alkyd resins produced by the reaction of ester diol alkoxylate, polyol and polycarboxylic acid. The alkyd resins are useful in coating compositions as well as those other applications in which known alkyd resins are employed.
Abstract:
This invention concerns a curable composition comprising a mixture of:(A) the reaction product of an ester diol alkoxylate of the structural formula: ##STR1## wherein m is an integer having a value of from 2 to 4, preferably 2 or 3; n is an integer having a value of from 1 to 5, preferably 1 to 3 and most preferably 1; x and y are integers each having a value of from 1 to 20, preferably 1 to 10; R is an unsubstituted or substituted, linear or branched alkyl group having from 1 to 8 carbon atoms, preferably 1 to 3 carbon atoms, and an intramolecular anhydride of a polycarboxylic acid; and(B) an ethylenically unsaturated monomer.This composition can be used in the manufacture of fiber-reinforced plastic compositions.
Abstract:
High solids coating compositions comprising a polycaprolactone derivative and a mixture of a methylolated melamine and a low molecular weight polyol; and, optionally, solvent and catalyst. The polycaprolactone derivative used in the coating compositions is the reaction product of a polycaprolactone polyol, a polyisocyanate and an anhydride of a polycarboxylic acid; the polycaprolactone polyol has an average of at least two hydroxyl groups in the molecule, a hydroxyl number of from about 15 to about 600 and an average molecular weight of from about 290 to about 6,000. The carboxylic acid anhydride mentioned has at least one intramolecular carboxylic anhydride group. The polycaprolactone derivatives are water insoluble.
Abstract:
A photocurable composition based on a cycloaliphatic polyepoxide, a poly(tetramethylene oxide)polyol and photoinitiator; and a printed circuit board having as a conformal coating thereon, the cured product of the photocurable composition.
Abstract:
This invention is directed to photocopolymerizable compositions comprising an epoxide containing two or more epoxy groups, a poly (active hydrogen) organic compound, a photoinitiator and, as a reactive diluent, a substituted cycloaliphatic monoepoxide. The photocopolymerizable compositions have low viscosity and can be applied to suitable substrates by conventional methods and, after being cured to dry coating films, can have utility as automotive finishes, can finishes, appliance finishes, general metal finishes, adhesives, printing inks and the like.
Abstract:
This invention is directed to photocopolymerizable compositions comprising an epoxide containing two or more epoxy groups, a poly (active hydrogen) organic compound having at least some primary hydroxyl content and a photoinitiator. The cured coating compositions exhibit fast cure rates, good water resistance and can have utility as automotive finishes, can finishes, appliance finishes, general metal finishes, printing inks, adhesives and the like.
Abstract:
This invention is directed to photocopolymerizable compositions comprising a poly (active hydrogen) organic compound, a photoinitiator and, as a reactive diluent, a substituted cycloaliphatic monoepoxide. The photocopolymerizable compositions have low viscosity and can be applied to suitable substrates by conventional methods and, after curing, provide excellent pressure sensitive and heat-activated adhesive coatings.
