Master Bond LED401 is a breakthrough system based on LED technology. This adhesive, sealant, coating and encapsulant cures tack-free upon exposure to a 405 nm wavelength light source, without any oxygen inhibition. Optically clear, it is also safer and easier to handle than similar UV systems as LED lights emit substantially less heat than UV lamps. This makes LED401 a suitable choice for applications involving heat sensitive substrates.
As a one part system, LED401's open time is indefinite. It is a higher viscosity system at 100,000-150,000 cps, but maintains its flowability and convenient handling. With cure times of 15 to 30 seconds or less in thinner sections, depending upon the distance of the light source from the material being cured, it can also be readily cured in sections up to 1/8 inch thick. It bonds well to similar and dissimilar substrates, including most plastics, metals and ceramics. Additionally, this compound has superior adhesion to glass, polycarbonates and acrylics.
LED401 offers excellent resistance to a variety of chemicals including water, many acids, bases and oils. It has superior electrical insulation properties with a volume resistivity exceeding 1014 ohm-cm. Serviceable over the wide temperature range of -60°F to +250°F, LED401 features very good dimensional stability.
Master Bond LED401 has a shelf life of six months at room temperature without exposure to light, in its original containers. It is available in syringes, ½ pints, pints, quarts, gallons and 5 gallon containers. Other versions of this product are available with different viscosities and in an opaque white color.
