Sunrez "Light Cure" Technology

Sunrez "Light Cure" technology is the result of 20 years of modifications, improvements, and evolution of technology that was originally developed in German laboratories. We have developed a variety of polyester, vinylester, and urethane formulations (resins, prepregs, putties) which can be RAPIDLY cured at ambient temperatures(-40°F to 120°F) in seconds instead of minutes or hours.

This technology provides a huge set of advantages in both manufacturing glass reinforced laminates, and the repair and rehabilitation of structural parts. Light curing of resins is not a new technology, but the rapid and controlled curing of these resins under both hot and cold ambient conditions is a breakthrough. There are many advantages that come with the technology, including reductions in waste and environmental compliance problems.
