What are the types of structural adhesive

1. Neutral transparent silicone structural adhesive

This structural adhesive is ready to be extruded and used, the method is very simple. The bonding performance is very good, it will not affect the surface of the bonding substrate, and there will be no aging phenomenon, and the performance is still very stable. After curing, it can carry 25% of the expansion and contraction displacement of the interface, which can effectively relieve the vibration, elastic pressure and pulling of external forces, and give the substrate a stronger bonding effect.


2. Acrylic structural adhesive

Fast curing, high strength, initial fixation in about 5 minutes, 80% strength after 30 minutes, maximum strength after 24 hours; excellent acid and alkali resistance, water, oil medium, high temperature resistance, better aging resistance, good for Strong adhesion between metal objects, better impact resistance than epoxy resin, excellent cold and heat resistance, working at -30 ~ 150 ° C.

So are structural adhesives and weathering adhesives the same type of adhesive? Actually not, there is a big difference between the two, let's take a look with Baigao below!

The difference between structural adhesive and weathering adhesive

In terms of properties, weather-resistant adhesive is a low-modulus neutral silicone sealing material, and structural adhesive is a neutral curing structural adhesive; in terms of performance, weather-resistant adhesive has strong weathering resistance, and structural adhesive bonding is superior; in terms of use, weather-resistant adhesive is mainly used. For the weather-resistant sealing of glass curtain walls, structural adhesives are mainly used for the reinforcement and bonding of components.
