SETALUX® 27-1550

SETALUX® 27-1550 is a hydroxyl-functional acrylic oligomer primarily used in 2K high solids industrial air dry, force dry, and bake applications. Coatings formulated with SETALUX 27-1550 exhibit excellent overall performance properties, including high solids, low VOC formulation potential, excellent flow and leveling, good flexibility, and early water resistance. Here's a breakdown of its key features and specifications:

Introduction:
SETALUX 27-1550 is an acrylic polyol delivered in 80% non-volatile content in methyl n-amyl ketone. It is designed for use in high solids coatings for industrial applications.

Performance Highlights:

• Ability to formulate low VOC coatings (2.3 – 2.8 lbs/gal or less)
• Excellent flow, DOI (Distinctness of Image), and overall appearance properties
• Very good exterior durability and gloss retention
• Very good early water resistance

Suggested Uses:

• Topcoats and single coat enamels for industrial applications
• Maintenance and marine coatings
• Coatings for metal and plastics
• Modifier for both acrylic and polyester urethane and melamine cross-linked systems
