The Master Bond LED401 is an adhesive, sealant, coating and encapsulant that cures tack-free upon exposure to a 405nm 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 3mm 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. Other versions of this product are available with different viscosities and in an opaque white color.
