Structural adhesive is widely used in engineering projects. Structural adhesive is divided into two categories. What are the two categories? Below, take a look at some of the content shared by 995 structural glue sales company!

    1. Epoxy structural adhesive

    Epoxy resin structural adhesive is a non-solution, liquid component epoxy resin adhesive, can be cured at room temperature or high temperature. After curing, the layer is of moderate strength, so it can withstand strong shock and vibration. This layer has excellent mechanical equipment characteristics, excellent electrical insulation properties, and can withstand temperature changes and tensile strain tearing stress. Non corrosive, good adhesion to metal materials, porcelain, rubber materials, glass fiber products and carbon fiber materials.

    Epoxy structural adhesives cure at room temperature without heating or working pressure. Heat is known to speed up curing. There are no volatile organic compounds throughout the curing process. Generally, glue with a thickness of about 0.8mm can be fully bonded at the bonding joint. When the curing temperature is lower than 15℃, the actual bonding effect will be very poor. The actual bonding effect can be obtained by curing at 25℃~70℃.

    2, acrylic resin structural adhesive

    Acrylic resin structural adhesive is a structural adhesive composed of acrylic resin and modified material curing agent. Fast curing, high strength, up and down five minutes can be fixed. After 30 minutes can reach 80% strength, after the strong. Excellent corrosion resistance, water resistance, oil resistance, stronger heat resistance and aging resistance, good adhesion to metal materials, impact resistance is better than epoxy resin, excellent heat resistance, cold resistance, working temperature below -30~150℃.
