The present invention provides compositions for and methods of rapidly making roof coatings, wherein two-component aqueous compositions comprise a component one that has a pH of from 7.5 to 10 (i) one or more emulsion copolymers having a glass transition temperature (Tg) as determined by differential scanning calorimetry (DSC) of from 45 C. to 0 C., and (ii) one or more anionic surfactants, and, in a separate component, (iii) an aqueous acid chosen from a (poly)carboxylic acid or polymeric polyacid. The compositions have little or no ammonia, set within 10 minutes, preferably, a minute or less, and allow one to apply a film as thick as from 0.3 to 3 mm in a single application by co-spraying the two-components or applying them sequentially in one or several passes over a roofing substrate.

The present invention provides emulsions comprising curable polyesters and certain surfactants. The emulsions are useful as coatings binders in waterborne thermosetting coating compositions and can be used in conjunction with cross-linking compounds reactive with curable polyesters. Also provided are shaped or formed articles coated with the waterborne thermosetting coating compositions of the invention.

It discloses a lignin enhanced wood-plastic composite, belonging to the field of polymer based composites. The wood-plastic composite is composed of one or more of plant fiber, lignin, a recycled thermoplastic plastic, mineral powder and a processing aid, and is processed by a screw granulating extrusion process. Compared with the prior art, the mechanical properties, heat stability and aging resistance of a wood-plastic material are improved by adding lignin into the wood-plastic material according to the present invention.

The invention relates to a process for preparing an amine adduct, in which a polyamine component (A), a polyester component (B) and a hydrocarbon component (C) are reacted. The amine adduct is of particularly good suitability as a wetting agent and dispersant, especially for coatings and plastics applications.
