How can I overcome coating defects when formulating a low-VOC, water-based coating for plastic substrates?

Jeanine Snyder
Senior Development Chemist 

Applying waterborne coatings on difficult-to-coat surfaces like plastics, films and non-porous substrates presents significant challenges for the coatings formulator. Maximum wetting and minimal defects require the proper surfactant to promote substrate wetting and minimize foam generation. Air Products' Dynol™ surfactants offer a superior balance of properties compared to traditional silicone and fluorosurfactants. Based on Gemini technology, the Dynol 300, 600 and 800 series surfactants have the ability to reduce both equilibrium and dynamic surface tensions to levels not achieved with other surfactants. These organic superwetting surfactants offer superior dynamic surface tension reduction under diverse application conditions. Our new, low-foam siloxane-based Dynol 900 series surfactants offer premium equilibrium and dynamic surface tension reduction making them the ideal choice for plastic substrates when foam cannot be tolerated.
