CHEMK UV-5050 is a liquid light stabilizer blend developed specifically for coatings. Its high thermal stability and permanence makes it suitable for coatings exposed to high bake temperatures and/or to extreme environmental conditions. It has been designed to fulfill the high cost/performance and durability requirements of trade sales and industrial coating applications. Its broad UV absorbance allows effective protection of light sensitive substrates such as wood and plastics.

Application：
CHEMK UV-5050 is a versatile light stabilizer which can be used in a wide variety of clear and pigmented coating systems, based on water-borne or solvent-borne paint technology. Its use is especially recommended for clear and light pigmented coatings in applications such as:
● Wood Coatings(esp. water-borne acrylic dispersion based systems);
● House and Trim Paints (esp. water-borne acrylic dispersion based coatings);
● One-component or two-component polyurethane coatings;
● Industrial Sroving Finishes(e.g. alkyd, PES/melamine systems or PES/NCO-systems);
● Car Waxes, Car Polishes and Vinyl Protectants;
● Unsaturated Polyster (UPES)/Styrene Gel Coats;
● UV radiation curable acrylics and UPES resin based systems;
The dispersion of UV-5050 in water borne coatings may be facilitated by dilution with a water miscible cosolvent such as butyldiglycol and Texanol. (Texanol is a registered tradedmark of Eastman Chemicals).
