Antifoam product M688 with low surface tension,easy to disperse in applicaiton system, Has the wetting effect to the base material, not easy to produce fisheye.This product is non-toxic and odorless, which is conducive to production safety
When air enters the liquid, the "cavitation effect" of the liquid results in a large number of bubbles, accompanied by rapid agitation and other operations.These bubbles can be divided into visible and invisible bubbles. For some physical defoaming methods, such as vacuum defoaming, only visible bubbles can be eliminated, but the effect of removing fine bubbles in liquid is not good.
Due to production is solidified by polymerization of epoxy resin, the reaction is exothermic reaction, so in the curing reaction, will as the reaction progresses, the rise of temperature makes tiny bubbles heated expands in the epoxy resin system, gas no longer compatible with epoxy system migration will happen to aggregate together to form larger bubbles.
Mineral oil defoamer M688 it is composed of mineral oil, metallic soaps, silica and dispersants. It is one non-silicone antifoam agent, it offer quick bubble break and excellent foam suppressing performance.
