Avoiding Alkylphenol Ethoxylates in Waterborne Adhesives

Andy Extance – Mar 6, 2012

As we understand ever more about how chemicals interact with the environment, adhesive formulators frequently have to face upheaval in reconsidering which components they can use in their products. A prime example of this is the progressive reduction in permissible emissions of volatile organic compounds, which has driven a wholesale shift towards water based pressure sensitive and laminating adhesives. But compared to the solvents that it replaces water has a high surface tension potentially making gaining good coverage of films, silicone release liners and other low energy surfaces difficult. Consequently surfactants are widely deployed as wetting agents to provide enhanced surface coverage and more uniform distribution.
