Product features:

Can be quickly dissolved in a wide range of polar and non-polar organic solvents.

Easy to emulsify in water.

Properties and uses:

Liquid UV absorbers for the phenyl and triazole-class UV absorbers, can effectively protect the coated gloss, to avoid cracking and spots, this product is easy to emulsify, especially suitable for aqueous systems.

Liquid UV absorber in dispersion of waterborne systems can be dissolved in diethylene glycol water soluble solvents such as ether, access.

Liquid UV absorber has a good resistance to high temperatures and extraction features especially suitable for high weather resistance requirements for industrial and automotive paints, liquid UV absorbers can also provide adequate protection to sensitive substrates such as wood class.

Liquid UV absorbers and hindered Amine (HALS) to share, such as light stabilizer 292 or 123. These shared collaborative agent that can significantly improve performance, prevent loss of gloss, cracking, blistering, and peeling and discoloration. Application: liquid UV absorber in dispersion of waterborne systems can be dissolved in diethylene glycol water soluble solvents such as ether, access. Liquid UV absorber is recommended for solvent and waterborne coatings: 8226; automotive paint 8226; industrial coatings 8226; commercial sales coating liquid UV absorbers and hindered Amine (HALS) to share, such as 144,292 or 123. These shared collaborative agent that can significantly improve performance, prevent loss of gloss, cracking, blistering, and peeling and discoloration. As light stabilizer can be added to automotive varnish or primer. However, according to our experience, adding light stabilizer in the paint protection work best.

Solubility (at 25 deg c, 100ml grams of solvent can dissolve)

Toxicity and safety:

No irritation to the skin, without any harm to the human body, processing, operation, handling process is safe and secure.

Liquid UV absorber storage conditions:

Should be placed in a dark, well-ventilated place, keep dry, not direct sunlight exposure.
