PARALOID™ A-646 Resin

Very hard methyl methacrylate polymer supplied at 45% solids in MEK. PARALOID™ A-646 Thermoplastic Solution Resin (45%) is a lower molecular weight analog of PARALOID™ A-101 Thermoplastic Solution Resin (40%). The lower molecular weight of allows for higher solids formulations. Coatings based on PARALOID™ A-646 Thermoplastic Solution Resin (45%) are also lower in viscosity for higher gloss and better reflow than PARALOID™ A-101 Thermoplastic Solution Resin (40%). Recommended for clear coatings for metal and wood, gravure printing inks, and barrier coatings for plastic. It has excellent adhesion to plastic substrates and primer coats, is fast drying, highly durable, and has excellent resistance to water and salt spray. As with all hard PARALOID™ Thermoplastic Resin coatings, the best gloss and adhesion are obtained if films are force dried after application.

Uses:

  • General industrial finishes

Benefits:

  • Enhanced gloss
