How to Read the Graph of the Lab Test Report

The Graph Tells the Story.

• The numbers on the left are the load measurement in Newtons.
• The bottom numbers are the time of failure in seconds.
• The first dip in the graph is when the repair failed and that is the score of the repair.
• The second dip is when the other layer of glass failed or broke.

Comments - The New (2023) Ultra Bond Windshield Repair Tool with 100 resin scored 100% of new laminated glass strength.  Note: this tool is one of its kind with both the grommet sleeve and a vacuum seal on the piston and a double cylinder chamber creating more vacuum and pressure than just the grommet seal type injectors. Vacuum improves wicking and pressure increases wetting. It also degasses the resin like an O-Ring sealed piston. Other tools with a grommet sleeve (Delta, Novus, Amazon and Walmart DIY Kits) have little to no vacuum, cannot degas the resin and one cylinder chamber.

Permatex D-I-Y Windshield Repair Kit

Test Components:

1. Disc and syringe
2. Permatex Resin
3. Sunlight Cure
4. Break Type - Star-Break/Combination Break
5. Method - Vacuum and Pressure

New Glass Score = 590 Newtons, SD - 59

Repair Test Score = 58% of New Laminated Glass Strength

Conclusion - The Permatex D-I-Y Windshield Repair Kit scored 58% of new laminated glass strength in the break types required by the ROLAGS which is a star/combination break. This kit specifies that it is for bullseye breaks which are the round shaped breaks that were prevalent when windshields were much thicker prior to the first gas crunch in the 1970s after which the thickness of windshields were cut in half to reduce weight to improve gas mileage. This reduction in glass thickness was also the beginning of windshields becoming the number one insurance claim in the United States. The bullseye in modern windshield is rare because the glass layers are only 2 millimeters thick and break into a star/ combination break instead of a bullseye.

Delta B-250 Windshield Repair Kit

Test Components:

1. Delta B-250 Tool
2. Delta Magnibond 18cps Resin
3. Delta LED Cure Light
4. Break Type - Star-Break/Combination Break
5. Method - Vacuum and Pressure, NO cure under pressure

New Glass Score = 590 and 547 Newtons (multiple batches' of glass)

Test Score = (275, 330) and 330 Newtons or 53% of New Glass.

Comments - The Delta B-250 Windshield Repair Kit with Magnibond 18cps Resin and their high intensity LED curing light scored 53% of new laminated glass strength. Delta for over 30 years is the ONLY Professional Manufacturer that does NOT recommend curing under pressure even though their resin manufacturer recommends it. In my opinion this is puzzling to me as pressure in any low viscosity adhesive application increases the bond, which is why all the others recommend it.  It is a fundamental fact of adhesives. They say they do exhaustive testing but disclose no numbers. They must not have compared curing under pressure versus not curing under pressure because we did and curing under pressure with their tool and their resin was 16 points higher or 20% stronger. You should request a 3-Point Bend Lab Test report with NUMBERS if you buy from them.   SD on the new glass was low at  59 and 21.

2. Gray Tinted Resin
3. LED ProCure+ curing light ($280.00)
4. Break Type - Star-Break/Combination Break
5. Method - Vacuum and Pressure, cure under pressure

New Glass Score = 547 Newtons, SD- 21

Repair Test Score = 208 Newtons or 38%, SD- 105

Comments - Glas Weld stated at a ROLAGS meeting in 2023 that they have done these ROLAGS Lab Tests. Once they disclose those results, we will put them up here. You should ask for the report. This was the most problematic system tested. Had to be retested multiple times due to cracking-out during thermal cycling and then a process of elimination to figure out the problem(s). Their previous Eco Vac tool scored much better; the difference being a threaded mounting system versus a click-in mounting system and a fluorescent cure light. Compression on the glass with the Zoom Tool click-in mounting is weak and not controlled by threads (all other professional systems and most D-I-Y Kits use threads). YouTube videos by users and Glas Weld shows it leaks, wobbles in the tripod and are always having to manually flex legs with a probe to get them to fill even when using a water thin 18 cps resin. Threaded mounting offers feel and precise control of the pressure/compression on the glass and the seal. This click-in is by manually pushing down on the injector ???? This can result in an underfill instead of a compete fill if you do not push down hard enough, which you may have a tendency to do to prevent spreading the break, especially on a hot windshield. If the initial push to seal the injector seal on the glass is not enough and it leaks resin, as it usually does on the YouTube videos of this tool, instead of a slight turn with a threaded mount you have to push down on the injector . The Procur+ LED light seemed to be not producing a proper cure either. LED Cure lights do not give off uniform UV Energy which creates tension/weak-spots in the cured resin. LED cures have the lowest lab test scores and have the highest standard deviation because each LED Bulb gives off a different intensity and they diminish over time each at a different rate, which means a lack of consistency. We compared the Procur+ versus a $9.95 Fluorescent using the same resin in an Ultra Bond tool. The 365 nm fluorescent scored 89%; the Procure LED scored 57%. In my opinion it is hit or miss with the click-in mounting and the Procur+ Light.

3M D-I-Y Windshield Repair Kit

Test Components:

1. 3M bridge Tool
2. 3M resin
3. Sunlight Cure
4. Break Type - Star-Break/Combination Break
5. Method - Vacuum and Pressure, no cure under pressure

Repair Test Score = 202 Newtons or 34% of New Glass Strength.

Conclusion - The 3M Do-It-Yourself Windshield Repair Kit scored 34% of new laminated glass strength. In my opinion, this kit would have done much better with maybe a different resin AND or cured under pressure.
