The key word is layer - Activator is applied as a thin film or layer to one or both surfaces to be bonded. Adhesive base resin is applied to one surface and parts mated to start the cure reaction. Unlike epoxies acrylics require no direct mixing. Acrylics offer unique performance capabiliites. High peel and high impact stengths are combined to dilver tough, durable, shock resistant bonds.
Acrylics withstand weathering effects well.
Acrylic adhesives do not require extensive surface preparation and bond well to dirty and oily surfaces. Other acrylic feature include the ability to bond to a wide range of materials, excellent gap fills and fast fixturing times.
