Inside Curing Light with Lithium Battery

 This New Inside UV Curing Light PENETRATES through the PVB turning the PVB into the curing source. This shows three benefits; (1) significant visual improvement, (2) strength increase and (3) easier to use.

This inside UV curing light penetrates through the PVB so you can cure under pressure from inside the vehicle. Curing under pressure adds 10-20% more mechanical strength to your chip repairs.

The UV intensity is reduced down to the proper intensity range going through the PVB for our resins and is the same as our other lights curing from the outside.

We have run dozens of tests after thermal exposure followed by Mechanical Strength by 3-Point Bend using different resins and different tools, curing under pressure and not curing under pressure.

There is a significant visual improvement from the inside cure. What makes legs and chip repairs more visible over time is the fact that windshield resins are Free Radical UV Curing Acrylics that do not wet the PVB meaning there is no chemical bond to the PVB so the line where the glass of the leg, crack or bullseye meets the PVB can leave a skeleton or head-on-angle, especially when not curing under pressure. Curing under pressure keeps the resin in place by force and creates an overfill. Curing from the outside the light is on top of the glass and can pull the resin molecules as they crosslink up and off the PVB as you cure if you don't cure under pressure. Curing from the inside through the PVB turning the PVB into the curing source while the piston is in the pressure mode i.e. Curing under pressure which is pushing the resin down and now the cure also pulls the molecules downward forming an extremely tight bond at the line where the legs, cracks or bullseye meets the glass and PVB making the break virtually disappear. Even the head-on-angles are virtually invisible. See the magnified pictures of a 7-leg Star-Break after going through thermal exposure and after breaking the repaired laminate from our 3-point bend testing machine. 

Strength increase was evidenced in that both layers of the laminated glass broke at once. When that happens with the score in the range of the new glass samples, the score is 100% and means the repair stayed intact while the glass broke. 

This new light has a USB plug that can enable power to the light from many sources such as a car adaptor, lithium-Ion battery, 110 or a computer. Most cars from 2015 and up have a USB plug. Cures chip in about 2-4 minutes with our 50, 70 and 100 resins; cures in 3-4 minutes with our 18, 20, and 40 resins.  You want the resin in the pit to be fully cured or to at least a gel state when you remove the injector. Then use it to cure the pit on the outside for 60 seconds. Comes with a car plug adaptor and our universal light holder.

This package comes with a rechargeable lithium-ion battery, a car plug and a universal light holder. Cures in 2-3 minutes on the inside, then cure the pit on the outside for 60 seconds.

NOTE: It is vital to degas the resin by pulling a vacuum for 1 minute after you have resin in the break. This will pull any air bubbles out of the resin that are not visible to the naked eye.
