Title:
COATING COMPOSITION
Document Type and Number:
Japanese Patent JP3107737
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide novel coating compositions based on PVC plastisol containing thermoplastic microspheres suitable for use as undercoatings for vehicles for abrasion resistance and pebble impact resistance purposes.
SOLUTION: The objective coating compositions are based on PVC plastisol containing 0.1-5.0 (wt.)% (preferably 0.5-2.0%) thermoplastic microspheres which are a mixture of expandable microspheres and expanded microspheres at a ratio of 1:9-9:1 (preferably 3:1-1:3) in which the expandable microspheres expand at a temperature in the vicinity of the temperature (not lower than 140°C) at which the expanded microspheres begin to collapse. Further, the thermoplastic microspheres have a polymer shell housing a blowing agent, and the shell is formed of a copolymer of a monomer selected from (meth)acrylonitrile, vinyl chloride, styrene, etc.
