BLS® 1328
Applications: High solubility and superior properties make BLS® 1328 particularly suitable for light stabilizing in coatings, propylene, polyurethane and polyvinyl chloride. BLS® 1328 is also efficient for the light stabilization of unsaturated polyester, polyacrylate, polycarbonate, rigid and flexible polyvinyl chloride, ABS, epoxy, acrylic, and polystyrene. BLS® 1328 features strong UV absorption, low color contribution, and moderately low volatility which makes it highly recommended for protective coatings and a variety of automotive coating substrates like two component polyurethanes and thermoset acrylic enamels. BLS® 1328 has excellent solubility in urethane solvents, is non-reactive and has no effect on the cured properties of the coating while protecting against loss of gloss. In thermoset acrylic enamels the low volatility and high solubility of BLS® 1328 make it especially attractive in thermosetting acrylic finishes. BLS® 1328 protects against loss of gloss and is useful in thermosetting acrylic clear topcoats where it protects against interfacial adhesive loss between the topcoat and the base coat. BLS® 1328 is generally superior to other ultraviolet light absorbers in terms of retaining color after light exposure, especially when used in combination with BNX® 1010. BLS® 1328 can also be used in combination with hindered amine light stabilizers to provide enhanced performance.
Advantages:
- Strong absorption of ultraviolet radiation in the 290-400 nm region
- Readily soluble in a wide range of organic solvents
- Low initial color
- Low volatility during high processing temperatures
- Good extraction resistance
- Excellent compatibility with a variety of polymers
