Question: We want to bond steel to foamed polystyrene. What do you recommend?
Answer: Solvent-based contact cements, such as those based on chloroprene rubber, were traditionally used for this application. They work very well and are available in spray or aerosol versions. However, many users are now reluctant to use them because of emissions regulations, safety concerns or disposal issues. Water-based adhesives can be used for this application but tend to cure dry slowly because of the difficulty of evaporating the water.
