Suppressor 2132 is a low molecular weight compound that is useful in difficult systems where persistent foam cannot be resolved with ordinary foam control agents. The product is especially useful for controlling foam in UV-EB curable systems where quick dissipation of entrained air is required to produce the desired product. Suppressor 2132 eliminates unwanted air entrainment, as well as micro and macro- foam, without adverse effects such as pinholes and craters.
