Modified epoxy acrylate UV resin for wood and paper

Product Code: ZC8801A

The chemical name of product ZC8801A is modified epoxy acrylate. It is a water white or yellowish transparent liquid. Customers are mainly used in nail polish glue, ink, TPU, etc. The only disadvantage is the offensive odor. It has good flexibility, adhesion, water resistance and good resistant of yellowing. Epoxy acrylate is the most widely used light curing prepolymer. In terms of structure, it can be divided into bisphenol A epoxy acrylate, phenolic epoxy acrylate, epoxy oil acrylate and modified epoxy acrylate. As a main resin, epoxy acrylate cured film has good adhesion, chemical resistance and strength, but it also has disadvantages, such as insufficient flexibility and brittleness. Therefore, in order to meet the needs of different fields, the physical and chemical modification of epoxy acrylate has become one of the research hotspots in this field.

Physical modification is to add nanoparticles to epoxy acrylate to improve the properties in the curing process; Chemical modification is to use the epoxy group or hydroxyl group in epoxy acrylate to react with the functional groups in other modified substances to prepare modified products with different properties. Polyurethane modified epoxy acrylate is mainly divided into two categories: (1) polyurethane or polyurethane acrylate is added to epoxy acrylate UV curing system through physical blending. (2) The prepolymer containing isocyanate at one end was synthesized and then reacted with epoxy acrylate. If the amount of epoxy acrylate modified by physical mixing exceeds a certain amount, phase separation will occur. In general, the flexibility of the modified epoxy acrylate film becomes better after curing.

Product 8860T is a standard bisphenol A epoxy acrylate. It is a water white or yellowish viscous transparent liquid with good reactivity, fast curing speed, hard curing film and good pigment wettability. It is a benzene free substance and meets the requirements of VOC limit index of cigarette pack. It is mainly used for inks, coatings and adhesives with strict VOC content restrictions.
