1173 is a high-efficiency, non-yellowing UV photoinitiator. It has low odor, non-yellowing and good color stability for UV curing systems of unsaturated polyester systems and multifunctional monomers.
1173 is a versatile and efficient liquid photoinitiator for acrylate series UV curing varnishes on paper, metal and plastic surfaces. It is especially recommended for UV coatings that require only a slight yellowing even after prolonged exposure to sunlight.
The 1173 has excellent compatibility and can be easily mixed with other photoinitiators and prepolymers.
1173 Applied to the surface layer curing system.
1173 Suitable for acrylic photocuring varnish systems, such as varnish systems for wood, metal, paper, plastics, etc.
1173 It is recommended to add 1-4% w/w to uv cured coatings that are subject to long-term exposure to sunlight and yellowing.
Package: 25kg/drum, can also be designed according to customer requirements.
