In the transition to waterborne coatings, emulsion polymers – often referred to simply as latex – have served as one of the most common binders in architectural applications due to the achievable low VOC levels. While relatively environmentally friendly and easy to apply, commercial latex coatings have been known to be susceptible to some performance limitations unique to waterborne systems. The use of water as the carrier requires the use of a variety of water-soluble species, which can cause water sensitivity of the coating once applied. These water-soluble species are mostly surfactants, including wetting agents, colorant dispersions and emulsifiers. These emulsifiers are necessary for the process of emulsion polymerization in the synthesis and required for the stabilization of the latex binder. During the drying of coatings and in moist or humid conditions and even once fully cured, traditional surfactants are released from the emulsion particles, and being surface active, tend to migrate to the surface. This surfactant migration can cause leaching, visible as discoloration or a “snail trail” pattern, as well as a reduction in barrier properties, water resistance and adhesion. Non-leaching reactive surfactants, which can be permanently co-polymerized into the latex, offer the efficiency needed during emulsion polymerization without the negative effects on end-use performance of the coating.
