Should be used: mainly used for paper, wood, metal and plastic surface acrylic resin varnish coating UV curing. It has a very good non-yellow degeneration. Even if the cured coating is exposed to sunlight for a long time, the degree of yellow change is very small, so it is particularly suitable for high paint and ink requirements for yellow change.
Recommended uses as follows: light varnish, plastic paint, wood paint, binder, lithography ink, silk ink, flexible ink, electronic products.
The excellent thermal stability photolysis products include benzaldehyde and cyclohexanone, which have a certain odor. Photolysis without benzyl produces excellent yellow denaturation. Cryogenic free initiator
The yellow change of acrylic polyurethane under outdoor sunlight can be further reduced by adding the BASF damped amine photostabilizer TINUVIN 292.
Recommended dosage: coating thickness 5-20 μm 2 -- 4 % coating thickness 20-200 μm 1 -- 3 %
Absorption spectrum:
Storage requirements: This product should be sealed and stored in closed, dry, dark, avoid sunlight.
Safety tips: Details are provided in the Material Security Data Sheet(MSDS).
