A one-component, optically-clear, toughened UV curable polymer system called UV15-7SP4 exhibits a desirable fast curing rate at ambient temperatures even at section thicknesses greater than 1/16 in. Typical cure times range from as little as 5 to 10 seconds to 2 to 3 minutes at room temperatures depending on the type of UV lamp used.


Master Bond UV15-7SP4 is 100% reactive and does not contain any solvents or other volatiles. The UV cured polymeric material features low shrinkage, excellent adhesion to various substrates, and durability. It does not embrittle even upon exposure to low service temperatures. UV15-7SP4 has low shrinkage upon cure. UV15-7SP4 has a low viscosity and is easy to apply. It has a storage stability that exceeds 3 months at 75°F. It is available in 1/2 pint, pint, quart, gallon, and 5-gallon containers. For ease of application, it is also available in syringe applicators.
