POWDER SLURRY COMPOSITIONS WITH SOLID PARTICULATE CARBAMATE RESIN COMPONENT DISPERSED IN LIQUID AMINOPLAST RESIN CARRIER

摘要

The invention provides a powder slurry composition comprising a first solid particulate component (a) dispersed in a crosslinking component (b) having at least one crosslinking resin which is liquid at 20.degree.C. First component (a) is in solid particulate form having an average particle size of from 3 to 30 microns. Component (a) has a compound (i) having a T g > 40.degree.C and at least one carbamate or urea functional group, or a group convertible to a carbamate or urea group appended thereto. Crosslinking component (b) has at least one crosslinking resin (i) which is liquid at 20.degree.C. Most preferably, crosslinking component (b) will further include a self-crosslinking aminoplast resin (ii) having at least two aminoplast groups and at least two groups which are nonreactive with solid particulate first component (a) but which are reactiv e with said aminoplast groups. The powder slurry composition of the invention has a VOC of less than 1.0 lbs./gal and provides performance and application improvements over the prior art
