Windshield adhesive has been bonding for decades

Windshield adhesive is among the oldest bonding applications known to the automotive industry. The initial purpose of windshield adhesives was to keep vehicles´ windshield in place but nowadays they do much more. Similar adhesives are also applicable to other windows and direct glazing of a wide variety of vehicles.

Adhesives applied to and around windscreens support and improve the stability of the vehicles as well as contribute to safety in the event of crash by making sure the windshield does not detach from the frame. Additionally, the adhesives are environmentally friendly and they result in faster processes in both OEM and aftermarket applications.

Types of adhesives for windshield bonding

Polyurethane and silicone are traditional means of windshield bonding and sealing. However, the technological development now allows for smarter adhesive solutions such as silyl modified polymers and modified silane polymers. These are slowly replacing windshield silicone adhesive systems and polyurethane-based solutions.

For cars, an adhesive provides sufficient windshield bonding and sealing, but larger vehicles such as buses and agricultural machinery may require an additional sealant to protect the bond.

Silyl modified polymer windshield adhesives

Silyl modified polymer windshield adhesives exist as one and two component systems which are both easy to apply with the right equipment. They do not contain any solvents, isocyanates, halogens or silicones, which reduces their VOC close to zero.

Next to fast curing, the ultimate advantage of these windscreen adhesive systems is that they do not require a primer. This reduces the application time and eliminates costs of surface preparation.

Modified silane polymer windscreen adhesive systems

When one solution for multiple substrates is sought, modified silane polymer adhesives are a considerable option. They adhere well to materials such as wood, plastic, metal and composite materials. MS polymers are also extremely resistant to the elements and remain flexible at all times, which is beneficial to all kinds of glazing in vehicles.

Modified silane polymers are common in windscreen adhesive systems because they combine beneficial properties of other materials such as acrylates, urethanes, silicone and butyl rubber. They are easy and fast to apply and speed up the process remarkable thanks to their fast curing ability.
