Particulate novolac resins and aqueous dispersions are produced by condensing phenol with aldehyde using acid catalysis. Following neutralization, particulate novolac resin is formed by adding protective colloid to the aqueous mixture. Resin particle isolation can be aided by dephenolation.

Process for producing particulate novolac resins and aqueous dispersions

Coating compositions based on a binder which is the reaction product of lactone grafted onto hydroxy substituted polyphenylether possess improved properties useful for deformable substrates.

Lactone grafted polyethers in coatings for deformable substrates

The total solids and viscosity of high solids coating compositions containing hydroxyl functional acrylic copolymer base resins are decreased by incorporating up to about 30% by weight of a mixture of reactive diluents. The reactive diluents are a mixture of a reactive acrylic oligomer and a polycaprolactone hexol.

Additive for improving weathering resistance and decreasing viscosity of

Particulate resoles are produced by mixing phenol, formaldehyde and amine in an aqueous medium containing a protective colloid. The resoles exhibit improved cure rate and sinter resistance when an alkaline compound is added to the reaction mixture after particulate formation.
