PROTECTIVE COATINGS and labor due to fewer coats, and finally, reducing the time and expense of equip- ment cleanup due to the environmentally friendly nature of the waterborne systems. Applications range widely from equipment to vehicles to infrastructure where chemi- cal agent-resistant coatings are not speci- fied or required. References 1.
