RAPID UHS 420 VOC ”Ultra High Solid“ acrylic is a very fast curing 2-pack acrylic clear coat characterized by rapid early hardness. It is ready for polishing only after 15 minutes of forced drying at 60oC and cooling down. Very good flow and levelling properties. High gloss and final hardness. Outstanding durability due to chemical and weather resistance. Well balanced pot life enables safe application. Designed for use on solvent- and waterborne base coat. High solid and VOC conform product. CHARACTERISTICS: VOC limit 2004/42/IIB(d): 420 g/l VOC content for ready to use product: max. 420 g/l.
