After a bit research on the internet i got this.
car windshield needs replacement, but I am worried about the safety post replacement. How can one ensure that the right adhesive is used for this?
Very rarely do people worry about the adhesive used for glass replacement. When car owners go for glass replacement, they always select the original glass for replacement but do not worry about the adhesive which bonds the glass to the car. But we, at Windshield Experts use rubber based adhesive Polyurethane to provide extra safety for you & your vehicle.
Currently common products available in market for glass replacement are:
· Polyurethane
· Silicon
· Modified silicon
· Butyl
· Acrylic
· All above products other than polyuretheane are just sealants.
The fundamental difference between adhesive and sealant is:
Adhesives - They unite 2 unlike bodies together. Eg. Glass and metal.
Sealant - It has chemicals to form hard water proof coating. It only fills the gap & does not let water in.
The difference between Urethane (adhesive) and Silicone (sealant) are:
· Urethane is 90 times stronger than silicone
· Urethane is approved by OEMs whereas silicone is not
· Urethane has better elongation
· Silicone gets softened by high temperature & humidity
· Silicone is weak at joints and is messy
· Urethane forms an integral part of the structural support in today's automobiles. In case of a collision, it prevents the occupants from being thrown out of the car by holding the windshield in its place. Besides, in case of a roll over, it prevents the roof from caving in.
