High Performance, UV Curable Epoxy with Enhanced Chemical Resistance
HACKENSACK, NJ - Combining superior physical strength and fast cure rates, Master Bond UV16 is formulated for demanding bonding, sealing, and coating applications. It is a one component, no mix system and cures in one minute or less at room temperature with commercial UV light sources.
This 100% reactive epoxy is uninhibited by oxygen and does not release any solvents or volatiles during the curing process. UV16 will cure in thicknesses up to 0.125 inches and has a 2% to 3% shrinkage rate, which is substantially lower than most free radical UV adhesives. Once cured, it delivers a tensile strength exceeding 4,100 psi and a Shore D hardness over 75. Post-curing UV16 at 90° to 125°C for 30 minutes gives the adhesive a glass transition temperature of 135°C and enhances its chemical resistance.
UV16 offers superior chemical resistance, especially against acids and solvents. After a three month immersion in 20% sulfuric acid, it exhibited less than a 3% weight gain. UV16 had a weight gain of less than 2% when immersed in 90% isopropyl alcohol for the same amount of time. With a volume resistivity of 1.6x109 megohm-cm, this epoxy also features excellent electrical insulation properties up to 300°F.
Master Bond UV16 has a viscosity of 200 to 400 cps and adheres well to a wide array of substrates, including plastics, glass, and many metals. A higher viscosity version called UV16TK is also available. UV16 has a 6 month shelf life in unopened containers and is available in syringes, half-pints, pints, quarts, gallons, and 5 gallon pails.
