6. What is a windshield made of?
Ans: Modern windshields are made of laminated glass - a sandwich construction of two pieces of glass with a clear strong plastic interlayer. The outer layer of glass may crack if hit, but unless there is a severe accident the glass will remain in place adhering to the interlayer.
Original windshields are manufactured to meet stringent international safety standards, which cover such aspects as optical quality, strength, fracture performance and resistance to the effect of weathering.
7. How important is the condition of the windshield?
Ans: For safety reasons it is important to ensure that the windshield is maintained in good condition. Cracks and other damages can weaken the strength of the windshield and affect visibility through the glass.
Major damage may require the windshield to be replaced while minor damage can be repaired.
8. What holds your windshield in place?
Ans: Automakers use urethane adhesive to bond the windshield to the body of your car.
9. Did you know that proper windshield installation is as important to your safety as safety belts, air bags and anti lock brakes?
Ans: That's right! Today, auto glass is more than just a shield to protect the driver and occupants from wind, weather and debris. The modern-windshield contributes up to 40% of the structural strength of the car. Besides, the windshield also keeps you and your family from being thrown from the vehicle in case of a collision.
Proper auto glass installation is the key to your safety. There is a right way and a wrong way to install auto glass. Auto glass installation requires a very strong yet flexible adhesive to bond the glass to the vehicle frame. This adhesive must have great strength to withstand the pressures put upon it in the event of a collision. The most widely used adhesive is called "automotive grade urethane".
Insist that a strong automotive grade adhesive be used to bond the glass. Don't let the glass be installed on corroded metal.
10. How do you know that the original windshield was safe to begin with?
Ans: There are government and manufacturer requirements imposed on motor vehicles. Vehicle manufacturers must certify each make and model of the car to a specified standards. Both the adhesive and the installation process must pass actual destructive tests.
When you replace the windshield, be sure it is being replaced with original quality glass and same adhesive approved for the original installation. Insist that a strong automotive grade adhesive be used to bond the glass.
11. What is automotive grade urethane?
Ans: Automotive Grade Urethane is a unique product. It needs to be strong and flexible, it should bond to smooth and rough surfaces and be able to withstand adverse weather conditions and still be workable. Silicone and butyl were once the most commonly used sealants. Approved urethane adhesive is 90 times stronger than silicone or butyl. Today, automakers specify other adhesives to originally install windshields in nearly every domestically manufactured vehicle.
12. How is the strength of automotive urethane measured?
Ans: Automotive urethane strength is measured in two ways; tensile and lap shear. Tensile strength is measured by the pounds per square inch (PSI) of force necessary to pull apart two hard surfaces until the bond fails. If you fasten your coffee cup to the kitchen table and pull it vertically off the surface, the strength needed to separate it from the table would be called tensile strength. Automotive urethane usually has more than 1000psi of tensile strength. Lap shear strength is also measured by pounds per square inch unit failure. However, to test lap shear strength, objects are pulled in a diagonal fashion. If you were to pull the same coffee cup off the table diagonally, the strength needed to separate it from the table would be lap shear strength. Automotive urethane has more than 500psi of lap shear strength. This is especially important in collisions where a roll-over occurs. Strong lap shear strengths are important to add to the structural strength of the vehicle body.
13. How about flexibility of urethane when the vehicle is moving?
Ans: Just as strength is important, flexibility is equally important. Urethane must have flexibility to allow for vehicle movement. Your vehicle is not completely rigid. It bends and flexes with the roadway. The glass however is rigid. If the adhesive were too inflexible, the glass would break every time you drive over a rough road surface. Urethane must also adhere to different types of surfaces. Glass is very smooth yet the metal frame of the vehicle is rough. Automotive adhesives must be able to bond, with equal strength, to all of the various surfaces used in the manufacture of motor vehicles.
14. Is there a special way by which urethane cures or hardens?
Ans: Good question. Yes, one unusual thing about urethane is the way it cures or hardens. Unlike paint or other adhesive products that use a solvent carrier that dissipates into the air to dry or cure, urethane takes moisture that's present in the air (humidity) and uses it to cure the product to its strong, rubber-like consistency.
15. Will your replaced windshield give the same protection as the original?
Ans: Always install glass from an expert. They use glass and urethane adhesive to replace your glass with bond strength equal to that of the manufacturer's installation. Most local installers use a replacement adhesive that is not approved by car manufacturers. Be sure to ask. Drive the vehicle only when the adhesive has fully cured.
16. Why is it important wait for the prescribed time to drive away?
Ans: For safety in meeting both retention and roll-over, it takes time. The longer the urethane cures, the stronger the bond and the safer the car. Safe drive away time depends on temperature and relative humidity. The installer can show you the results of typical tests run at 70F and 50% RH. And for the next two or three days after drive away, it is recommended to open windows slightly and avoid slamming doors or washing the car. Professional installers may suggest additional safety precautions.
17. What if I need my vehicle immediately and can’t wait till the prescribed time?
Ans: You can safely drive away in just 2 hours after installation if the right Urethane is used. Always check for safe drive away time. Always wear seat belts and insist that all passengers wear them too
18. What happens if the humidity is low?
Ans: Low humidity slows down the cure rate of urethane products. So it stands to reason that moisture must be added to promote faster cure. In most cases, simply adding water after the installation will give the urethane enough moisture to begin the cure. However, in the situation where mobile service is offered in low moisture locations, the answer may not be as simple. Warm air holds more moisture than cold air. In cold dry climates, it may be necessary for the installation to take place under controlled conditions, such as a heated garage or repair facility.
19. Are there automotive adhesives that don’t need moisture to cure?
Ans: Yes! There are currently new adhesives in the market that require no moisture for cure, but they do need some warmth for the curing process. These products are usually a little more expensive than urethane, but the quick release of the vehicle may sometimes be worth the cost. Insist that a strong automotive grade adhesive be used to bond the glass. Don't let the glass be installed on corroded metal. Follow to the letter the directions given by your expert technician. Drive the vehicle only when the adhesive has fully cured. Always wear seat belts and insist that all passengers wear them too.
