Master Bond UV10TK40 UV Curable Compound Has Gap Filling Properties

Description: Master Bond UV10TK40 is a higher viscosity, one part UV system for bonding, sealing and coating with good optical clarity, excellent physical properties, chemical resistance and high glass transition temperature (Tg) of 140°C. UV10TK40 cures readily in 20-30 seconds when exposed to a UV light source emitting at a wavelength of 320-365 nm with an energy output as low as 20-40 milliwatts per cm². The rate of cure depends upon the compound’s distance from the light source, the thickness of the section and, of course, the intensity of the light source. It should be noted that the system can cure in sections up to 0.090-0.100 inches. However, when bonding, sections of a few thousandths of an inch are more than adequate. Master Bond UV10TK40 is not oxygen inhibited and therefore does not require any special treatment in that regard. It bonds well to glass, surface treated metals and plastics such as polycarbonates and acrylics, among others. Its chemical resistance is particularly good as it resists water, oils, acids, bases and solvents well. UV10TK40 is not only effective for bonding applications; it can also be used as a coating or sealant. The system does not contain any solvents or diluents and none are released during cure. UV10TK40 combines low shrinkage with dimensional stability. Its service temperature range is -60°F to +450°F. UV10TK40 is an electrical insulator. It is effectively used for high production applications where fast fixture times and rapid curing are critical. UV10TK40 is widely used in fiber-optic, optical, opto-electronic, electronic and related industries where very high temperature resistance and higher viscosity are needed.
