- Applications
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.
- 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.
