UV curable adhesive/sealant has high flexibility

Paul Boughton

Master Bond Inc has introduced a new one component, UV curable urethane elastomer called UV15X-5 for bonding and sealing applications.

This formulation is highly flexible and exhibits outstanding abrasion resistance. It is designed to withstand thermal cycling and mechanical shock.

UV15X-5 bonds well to both similar and dissimilar substrates. Bonds are durable and resist exposure to many chemicals. UV15X-5 is 100 per cent reactive and does not contain any solvents or volatiles.

Master Bond UV15X-5 cures at room temperatures in very short time periods upon exposure to UV light. The more powerful the light source the quicker the cure. Additionaly UV15X-5 will cure in thicknesses greater than 1/8-in thick. UV15X-5 is not air inhibited. No special inert atmosphere is required for curing.

UV15X-5 has high physical strength properties. It has a tensile strength of 1800 psi. Its Shore D hardness is 35-40 and its elongation is >170 per cent. Additionally it is transparent and has a refractive index of 1.498. It also offers superior electrical insulation properties. Its volume resistivity is >1012 ohm cm.

UV15X-5 is available for use in 1/2 pint, pint, quart, gallon and five gallon containers. It is also available for use in syringe applicators.
