Windshield repair resin is extremely important for repairing a windshield. But why is a windshield resin needed in the first place? Here are the key facts you need to know about windshield resin and why it’s necessary.
Why Are They Needed?
Windshield resins are needed when a car’s windshield breaks or cracks. When an object such as a chip hits the windshield, a crack can form and the glass does not remain intact. Uneven heating and cooling can also cause cracks in the windshield, which is known as thermal shock. All of these factors can result in damage.
How are Windshield Repairs Done?
In order to perform a successful repair, the entire crack needs to be evacuated from air and moisture. This means that once these are removed, the crack can be filled with resin. However, this process is not as easy as it sounds. Removing air and moisture is tricky and excess moisture can also cause the repair to fail again and again.
How to Choose a Resin
Choosing a resin needs to be based on performance. This means that the resin must cover all areas of the damage. There needs to be enough strength to withstand expansion and contraction the windshield might experience. It has been found that tensile strengths for resin consist of two different things: adhesive and cohesive strength. Adhesive strength means the resin adheres to the glass, and cohesive strength holds the glass together.
What Happens when the Resin is Applied?
Once the resin is applied, it is then cured. Curing the resin results when the monomers of the resin harden due to exposure to ultraviolet radiation. This is done through windshield repair operators’ special equipment. If the resin is not completely cured, a weak repair will occur and the repair may fail.
Windshield Repair: A Science
Windshield repair is a science, as there are many important procedures that must take place for it to be successful. Now that you know the facts, you can understand the process of windshield repair better and understand the importance of windshield resin.
