Typical Properties         

Product Form:                         Liquid

Freezing Point:                        -10oC


BLS 3039 is a highly effective to improve the light stability of a wide range of plastics, including PVC (flexible and rigid), polyurethanes, styrenic polymers, polyesters, polyamides, and acrylics. It is also useful as a light stabilizer in adhesives and coatings applications. Due to its inherently nondiscoloring nature, BLS 3039 is ideal for use in transparent or light-colored substrates. It is also non-interacting with reactive monomers (e.g. isocyanates) and metal-based polymerization catalysts. Due to its absorption characteristics, it is also suitable for use in combination with optical brighteners.


  • Strong UV absorbance, especially in the UV-B region
  • Convenient liquid form for easy handling and dosing
  • Compatible with all common PVC plasticizers
  • Non-discoloring in plastics, adhesives, and coatings
  • Chemically non-interacting with reactive monomers and metal-based catalysts
  • Suitable for use with optical brighteners due to its low long wavelength UV absorbance
  • Excellent compatibility with plastics, adhesives, and coating substrates

Guidelines for Use

Typical recommended loading levels range between about 0.1 and 2% by weight, depending upon the substrate, processing conditions, end use, and other performance requirements. Combinations with other light stabilizers such as HALS and benzoates often show enhanced performance. The exact formulation 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.


This product may be stored up to two years in a sealed container. Containers should be kept tightly
closed when not in use and stored in a cool, dry place. Avoid storage at low temperatures (< 0 degrees Celsius) to prevent crystallization.
