Master Bond UV22 One Component, UV Curable, Nanosilica Reinforced Epoxy System
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Key Features:
  • Exceptional abrasion resistance
  • Superb optical clarity
  • Low shrinkage upon curing
  • Superior dimensional stability
Product Description: Master Bond UV22 is a nanosilica filled, UV curable, epoxy based system for bonding, sealing, coating and encapsulation. It is 100% reactive and does not contain any solvents or diluents. It is also completely free of any oxygen inhibition. This nanosilica filled system retains full optical clarity and has enhanced abrasion resistance, dimensional stability and unsurpassed low shrinkage. UV22 will cure quickly and easily when exposed to a UV light source with a wavelength range between 320-365 nm, with the optimum at 365 nm. The energy required is typically 20-40 milliwatts per cm². The rate of cure depends upon the distance of the light from the material being cured, the thickness of the section and the intensity of the light source. It typically cures in thicknesses of a few microns to about 1/8 inch in 15-45 seconds depending upon the depth of cure. Epoxy based UVs are described as having a “cationic” curing reaction. This kind of system will typically offer higher temperature resistance than the majority of other UV systems. UV22 has excellent resistance to a wide variety of chemicals including water, acids, bases, fuels and many solvents. It features superb physical strength characteristics and electrical insulation properties. UV22 has superior adhesion to a wide variety of substrates including plastics, glass and many metals. As is typical with UVs, it has excellent optical clarity and light transmission properties. UV22 has exemplary low shrinkage properties, linearly less than 1%. In order to attain optimal properties, especially temperature resistance, a post cure with heat is recommended. Cationic systems, such as UV22, tend to have much higher temperature resistance than other UV type systems. Its glass transition temperature (Tg) with a straight UV cure is 100°C, and when post cured for 30 minutes at 125- 150°C, the Tg is 135°C. This post cure also enhances UV22’s chemical resistance. The service temperature range for this system is -80°F to +350°F. It should be noted that there’s no settling out of the nanosilica filler and the product retains its uniformity throughout its shelf life. It is widely used for a variety of applications in the optical, optoelectronic, aerospace and related industries.

Product Advantages:

  • One component system; no mixing needed
  • Nanosilica filled, enhanced dimensional stability and superior abrasion resistance
  • Not oxygen inhibited. Cationic type cure
  • Superior temperature resistance, especially when post cured with heat
  • Outstanding optical clarity and light transmission
  • Passes NASA low outgassing test requirements
