UV curing coating mainly consists of five parts, namely to UV curable synthetic resin (also known as oligomers or pre polymer) as the basis, adding specific active diluent (also known as reactive diluent monomer), photo initiation agent (also known as photosensitizer), solid filler, and a variety of add agent (agent) is formulated and.

1, UV curing resin (or oligomer): including unsaturated polyester, polyester acrylate, polyether C

Acid ester, alkyd acrylate, polyurethane acrylate, epoxy acrylate, etc, are the main body of the coating, and determine the

The main properties of the coating;

2, UV curing active diluent (monomer): active monomer is mainly to adjust the viscosity of the paint, and participate in solid

Chemical reaction, affecting the performance of coating.

The active diluent was divided into two groups, one functional group and one group:

A; single functional active diluent is mainly styrene, acrylic acid, vinyl ether, etc.. Its main function is to make

For thinner, also have a certain impact on the performance of the coating.

B: multifunctional active diluent has two functional groups, three functional groups and multi functional porch, etc.. Its function is not to make the system

Increase the viscosity of the film to increase the crosslinking density. Of course, by using different types of multi functional groups

Release agent, can partially change the performance of the film.

3, photoinitiator: photoinitiator or photosensitizer. The effect of photosensitizer is the absorption of UV processing energy, polymerization,

Under the excitation of near UV light, free radicals are produced, which are sensitive to light and heat stability. Aromatic carbonyl compounds, organic sulfur

Compound, organic peroxide, etc..

4, solid filler: including pigments, extinction powder, wear resistance, etc..

5, additives (additives): the different additives play a different role, such as pigments, stabilizers, including leveling agent,

Anti foaming agent, dispersing agent, organic solvent (adjusting viscosity light, lustre degree, etc.)
