Molecular Weight: 277.33 g/mol
BLS 3035 is a highly effective to improve the light stability of a wide range of plastics, including styrenic polymers (ABS, ASA, HIPS, TPE’s), PVC (rigid and flexible), polyesters, polyamides, polyurethanes, and acrylics. The product is also useful as a light stabilizer in adhesives and coatings applications. Due to its inherently non-discoloring nature, BLS 3035 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. It is also suitable for use in combination with optical brighteners.
- Strong UV absorbance, especially in the UV-B region
- Non-discoloring in plastics, adhesives, and coatings
- Chemically non-interacting with reactive monomers and metal-based polymerization 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.
Please consult the Safety Data Sheet (SDS) prior to handling or using this product.
BLS 3035 has not been cleared by the FDA for use in food contact applications.
