Molecular Weight:                 Mixture


BLS 1130 is a liquid UV absorber providing excellent protection against ultraviolet degradation in coatings, including automotive and industrial coatings, paints, and wood stains. It is ideal for use in both water- and solvent-based systems. Combinations of BLS 1130 with hindered amine light stabilizers such as BLS 292 often provide significantly enhanced performance, providing maximum long-term protection against blistering, color change, cracking, gloss reduction, and delamination. BLS 1130 is also ideal for use in other applications where a liquid UV absorber is preferred, including polyurethanes, adhesives, sealants, liquid color concentrates, elastomers, styrenic polymers, acrylics, PVB, flexible PVC, polyesters, polycarbonates, and polyolefins.


  • Excellent miscibility with coating solvents
  • Thermal permanence and low volatility for high temperature curing
  • Compatible with a wide variety of systems including waterborne
  • Synergistic performance with other light stabilizers (HALS)
  • Extends coatings lifetimes by minimizing defects such as loss of gloss and cracking

Guidelines for Use

Typical recommended use levels in coatings range between 0.5% and 3.0% based on total solids. The dispersion of BLS 1130 in waterborne coatings may be facilitated by dilution with a water miscible solvent. In plastics, adhesives, and sealants, recommended use levels range between 0.1 and 1.0%. The exact amount to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use. Please contact Mayzo for specific recommendations.
