General
Vinapor® DF 2938 F (stab.) is a powder defoamer based on a mixture of an alkoxylated fatty alcohol with a polyetherol fatty acid ester on an inert carrier material. Vinapor® DF 2938 F (stab.) can improve the quality of fresh mortars by reducing the air content and increasing the density. It is especially suited for controlling the air content to achieve optimal freeze-thaw resistance. Vinapor® DF 2938 F (stab.) can be mixed with all other powder components without any problems. Fields for application are e.g.: non-shrink grouts, joint grouts, repair mortars, dry-mix concrete.
