Adhesives and Epoxies Q&A
-
I need to attach a 1.58-mm piece of polyethylene to another type of material, such as wood, plastic, or metal of various types. Any ideas?Answered November 30th, 2010 by Expert:It is very difficult to achieve strong adhesion to polyethylene, which is a polyolefin. A common method to overcome this issue is to pretreat the surface via corona discharge, gas plasma, flame treatment, or priming. These methods typically increase the surface energy of the substrate and the potential to adhere to it. Utilizing any of these pretreatment methods will open up the choice of possible adhesive products. To bond surface-treated polyethylene to wood, plastic, or metal, you can use a cyanoacrylate (RX-50 from Pacer), epoxy (Master Bond EP21), or polyurethane (Master Bond EP30D12).
The right adhesive choice for you is dependent not only on the dimension, design, and substrates you are trying to assemble but also the environment the device/item is being subjected to. Is it being used indoors with no contact to moisture or outdoors with consistent contact to water? For a dry environment, a cyanoacrylate might be the right choice, whereas an epoxy might be better for a moist environment.
