Adhesive Overview
What types of adhesives are there? Here is a summarized overview:
After the solvent or dispersion (usually water) evaporates, the parts can be joined immediately and are instantly load-bearing after bonding. The bond remains flexible. The substrates should be as smooth and even as possible.
Also called instant adhesives (super glue), they cure at room temperature with air humidity. They are often used for spot bonding. Curing takes place within seconds.
Reactive adhesives that cure by mixing two components. The adhesive can range from liquid to paste-like and cures relatively quickly after the pot life. The bonds are shock- and impact-resistant after curing.
Single-component, solvent-free adhesives that cure in contact with metal and in the absence of oxygen. Different strength classes and viscosities are distinguished.
Also single-component adhesives that cure when exposed to UV light. The parts must be joined beforehand so that curing starts immediately upon irradiation.
Very durable, extremely resistant to aging, chemicals, and weathering, with good shear strength.
Often used as one-component adhesives, they cure with air humidity and are considered permanently flexible bonding and sealing materials.
Reactive adhesives with very high strength values. By mixing the two components (resin and hardener) and considering the pot life, these adhesives cure into a very strong bond.
Available as one- or two-component adhesives. They offer high strength and fast curing times and are often used in structural applications.
Permanently tacky adhesives mainly used for adhesive tapes and self-adhesive labels.
Solvent-based acrylate, pure acrylate, modified acrylate, UV acrylate, dispersion acrylate.
Rubber has excellent adhesion but is less suitable for outdoor applications.
Silicone has high adhesive strength with high temperature resistance.
