Waterborne UV-absorber F-22 is a special water based paints, water based paints, water based ink light stabilizers of his maximum absorption wavelength between 290mm-420mm, can effectively prevent aging, yellow paint, paint, paint is peeling, flaking, coatings additives. Hindered amine is a powder of waterborne UV-absorber for many polymers with UV absorption, with capture of polymers by ultraviolet light produces free radicals function, without thickness against the effects of aging, but also have long-term resistance to thermal oxidation of.

Waterborne UV-absorber F-22 indicator:

Appearance: white or off-white crystalline powder odor: odorless

Melting point: ≥ 300 c content of more than%:98.0%

Moisture: ≤ 2%

Waterborne UV-absorber F-22 main uses:

This new waterborne UV absorbers, maximum absorption wavelength between 290mm-420mm, at 302 nm UV wavelength absorption coefficient as high as 925~980, its ability to absorb ultraviolet rays more than three times times are common absorbers, nontoxic, nonirritating, mainly used in waterborne coatings ink and water based paints, water based resin.

Waterborne UV-absorber F-22 content:

Recommends adding a thousand 3~5 paint, paint, this product will be dissolved in 10 parts of water using NaOH adjusted to pH 8 and added it to the paint, paint.

Storage: store in a dry, dark, airtight container; if crystallization occurs when Cryopreserved, cooking can be.
