Ultra Bond's New 20cps Crystal Quartz Windshield Chip Repair Resin; 105% New Windshield Glass Strength

NEW Crystal Quartz Resin as of May 2026. At Ultra Bond we altered the formula. Stone-Breaks will disappear and the 3-Point Bend Test score increased to 105%, which meets Pre-Loss Condition. We also eliminated the need to cure under pressure (CUP). Not curing under pressure (CUP) normally can reverse the wicking of the glass that took place and with low viscosity (under 40-45cps ) there will be shrinkage.  With the Wonder Bar Tools, both the 2-bar bridge and one-bar with the 3-inch suction cup and the Black Tool have pure compression. This mean the break and all the legs are flexed open at once symmetrically. When the flex is released (we call the "Flex and Release Method")  with the resin under pressure there is a forceful wicking of the glass and an overfill of the legs and bullseye. Doing this twice during the repair as shown in our videos with the new formula reached 100% + new laminated glass strength cured under pressure and not cured under pressure (CUP).

Scores by tool and curing light:


NOTE: With the Single Wonder Bar Tool with the 3-inch suction cup, Flex and Release by pushing on the end of the bar with your thumb and then release when the legs fill. Do this twice during the repair as shown with the videos of the Wonder Bar Fexing Bridge and Black Tool as well as the usual one minute vacuum during the repair to degas the resin.


TEST SCORES:

NEW 20 Resin:


  • Single Wonder Bar with the 3-inch suction cup, no CUP with 2 Bond Wands side by side =106%
  • Single Wonder Bar with the 3-inch suction cup, not cured under pressure (CUP) with (Round) Inside curing light on the outside only =103%
  • Inside Curing Light - CUP for one minute on the inside, removed tool, pit fill and cured outside, no CUP for one minute = 103%
  • Single Wonder Bar with the 3-inch suction cup, not cured under pressure with the (round) Inside Light on the outside only =107%
  • Black Tool, no CUP cured with 2 of battery fluorescent lights for two minutes  = 108%
  • Wonder Bar Bridge no CUP with 2 Bond Wands side by side, both layers broke at once meaning the repair remained intact = 100%+
  • Single Wonder Bar with the 3-inch suction cup, not cured under pressure (CUP) with 2 battery fluorescent lights side by side =105%


NEW 40 Resin 

  • Single Wonder Bar with the 3-inch suction cup, no CUP with 2 Bond Wands side by side ,remained intact =over 100%
  • Single Wonder Bar with the 3-inch suction cup, not cured under pressure (CUP) with 2 Bond Wands side by side =107%

  • Singe Wonder Bar with the 3-inch suction cup, not cured under pressure (CUP) with 2 Bond Wands side by side,  remained intact =100%+


50 resin - Single Wonder Bar with the 3-inch suction cup, not cured under pressure (CUP) with 2 Bond Wands side by side =108%


The 13 ml bottle will get you about 325 drops of windshield repair resin. This resin has the highest mechanical strength of any resin under 40 cps on the market at 105% new laminated glass strength.


What can cause a bubble in the pit when not curing under pressure?


The way you remove the tool and the way you pit fill.


There is no shrinkage with this resin.
1. Not flexing and releasing TWICE which causes the overfill so the resin comes out the pit when you are done and remove the tool. However when you are done and removing the tool you are doing the second release of the 2nd flex and release cycle on the break and glass while the resin is under piston pressure. With the Wonder Bar Flexing Bridge, 1st release the flex bolt off the glass, then slowly loosen the cylinder until all the flex on the break and glass is released. The cylinder should be loose, to the point where the resin could leak out. Then push the tool off the impact. The pit should be filled with resin.
2. Then level the resin in the pit with a razor blade. Do not wipe it out. Put pit filler /2400 or 1600 on top of the resin in the pit and roll the tab on. Then cure.
3. Also sometime during the first cycle degas the resin by doing a 1-2 minute vacuum. This is while in the 1st flex mode before you do the release of the 1st cycle.
