When looking to save money on energy costs and align a coating/converting operation with the latest environmental impact classifications, companies should consider the benefits of in-line manufacturing of adhesives.
This is a very interesting question. Many adhesives are used in what is called a “zero gap” situation, where the adhesive is applied between two closely fitting surfaces, which are then clamped together.
The primary forces are shrinkage of the adhesive on curing and large differences in thermal expansion coefficients between the substrates and the adhesive. High stresses can cause delamination of bonds or damage to the substrates, such as glass cracking.
We’ve been trying to get the metal button of a rear-view mirror to bond to a new windshield. We’re in the summer heat of Las Vegas where it is routinely over 110°F―and even hotter inside a closed car. We’ve tried all the typical glues but, while the button will cure and hold, it falls off when the mirror is attached.
