Abstract:
Polymers are disclosed that incorporate portions of secondary or tertiary polyamide segments connected with polyisocyanates. These polymers have enhanced matting properties. The enhanced matting properties are from creating an inherently matt surface from the polymer without the use of any separate fine particle size matting additives. Conventional matting agents such as fine particle size silica usually results in loss of physical properties such as haze development and porosity in the coating from the matting agent. Composites and hybrids of these polymers and other polyamides, polyurethane with vinyl polymers (acrylates) are also disclosed and claimed.
