New Optically Clear, Low Viscosity UV Curable Compound


Master Bond Inc., Hackensack, N.J. has introduced new UV19LV, a one component, high performance laminating, sealing, bonding and coating compound. This remarkable acrylic based polymer composition can effectively replace conventional heat/and or solvent based laminating adhesives for bonding and sealing clear films, sheets etc. to various other films, paper and foil substrates at substantially higher speeds and lower cost.

Master Bond UV19LV is an optically clear, mobile liquid, with a viscosity of less than 300 cps measured at 75°F. It is 100% reactive and does not emit any volatiles during cure. The UV19LV cure is not inhibited by air. It cures in 10-15 seconds using conventional UV cure equipment in the 365 nm range.

The UV cured material features an impressive tensile strength in excess of 800psi and elongation of more than 80%. It is a good electrical insulator and has low shrinkage upon cure. UV19LV has excellent adhesion to a wide range of substrates and is recommended for bonding to materials with widely different thermal expansion coefficients. It is also resistant to high impact, thermal cycling and mechanical vibration. It has a service operating temperature range of -60°F to +250°F.

Master Bond UV19LV has a shelf life of 6 months at 75°F. It is available in syringes, pints, quarts, gallons, 5 gallon pails and in drums.
