Effect of nano layered silicates on automotive polyurethane refinish clear coat

摘要

One of the more important challenges for automotive coatings, currently, is improving the scratch resistance (particularly via refinish coatings). One of the methods being studied is the use of nano-fillers to form an inorganic-organic hybrid composite material. Improvements in mechanical, thermal, electrical and magnetic properties have been reported (over the pure polymer properties), as a result of dispersing delaminated single layers of silicates.
