Abstract:
This invention relates to coating compositions and more particularly to highly productive coating compositions that quickly harden for sanding or buffing by incorporating therein a polyisocyanate adduct mixture into the coating composition as the crosslinking material. Such coatings are particularly useful for refinishing automobiles and trucks.
Abstract:
An ethylene polymer havinga) a Polydispersity Index, PDI, of about 3 to 9;b) an nRSI of about 5 to about 18;c) a cRSI of about 1.1 to 3.0;d) a Composition Distribution Index, CDI(100), greater than about 45; ande) a log-viscosity ratio, log(.eta.0/[.eta.]), of about 0.5 to about 1.5 is described. The ethylene polymer has improved processability over conventional linear low density polyethylene.
Abstract:
The present disclosure is directed to a coating composition having excellent adhesion to primer layers, fast drying, improved flexibility and good pot life. This disclosure is further directed to a coating composition comprising components derived from renewable resources, low Tg acrylic polymers having one or more crosslinkable functional groups and a crosslinking agent having one or more crosslinking functional groups.
Abstract:
The present invention is directed to a method for measuring sandability of a coating or an article. This invention is particularly directed to a method for measuring sandability of a coating or an article quantitatively by measuring weight loss of said coating or article after being sanded. This invention is also directed to a system for measuring sandability of a coating or an article using said method.
