TINUVIN® 5070 is a solvent-free, liquid blend of a 2-(2-hydroxyphenyl)-benzotriazole UV absorber(UVA) and a non-basic hindered amine light stabilizer (HALS) designed to fulfill the cost/performance and durability requirements of exterior solvent borne industrial and decorative coatings and is especially suited for oxidative drying and acid catalyzed systems.

TINUVIN 5070 is a versatile light stabilizer blend that can be used in a variety of coatings systems such as:

• Wood stains and varnishes, wood care products, waxes, candles
• General Industrial Paints
• Heavy duty maintenance and marine coatings
• Architectural coatings (roof tiles, walls, floor coatings)
• Glass and ceramic coatings (architectural glazing, packaging)
• Adhesives and bonding layers

Its use is especially recommended for clear and light pigmented systems like:

• Thermoplastics (Acrylics, Vinylics)
• Acid-catalyzed paints (Acrylic, PES/melamine)
• Oxidative drying systems (Alkyds, oils, waxes)

The broad UV absorbance of the UVA used in TINUVIN 5070 makes it suitable for a wide range of coatings for wood, plastics, and metal. The non-basic character of the used HALS prevents possible interactions with acidic paint ingredients such as catalysts, biocides, and pigments. The synergistic combination imparts superior coating protection against gloss reduction, cracking, blistering, delamination, and color change and provides full substrate protection.

Features & Benefits

• Synergistic blend of UVA/HALS for solvent-based coatings and adhesives
• Provides excellent photo-protection for coatings against loss of gloss, cracking, and color change
• Low basicity HALS enables formulating with acidic materials including acid catalysts and acidic pigments
