Nanosilica filled UV curable reinforced epoxy

Nanosilica filled UV curable reinforced epoxy
A new nanosilica filled one component UV curable epoxy called UV22 has been introduced by Master Bond. This compound has been developed for coating, sealing and encapsulation applications. It features superb abrasion resistance, excellent optical clarity, low shrinkage and high physical strength properties.

UV22 cures rapidly at room temperature upon exposure to a UV light source and is not oxygen inhibited. It has a service operating temperature range of -50degC to150degC. Post curing the UV22 material enhances its temperature resistance profile. Adding heat (90-125degC for 30 minutes) will give it a glass transition temperature of 135degC, far higher than traditional UV systems. The post curing is also effective in increasing its chemical resistance to solvents, acids and bases. In addition, UV22 is easy to use.

Despite the relatively high percentage of nanoparticles, it still retains high transparency and low viscosity without sedimentation due to the agglomerate-free colloidal dispersion of the nanoparticles in the resin. UV22 has a Shore D hardness of over 80 and a tensile strength of greater than 4,600 psi.
