Vinapor DF 2938 F (stab.)

Vinapor® DF 2938 F (stab.) is a defoamer in powder form optimized for repair mortars where a low air content without complete defoaming is needed. Vinapor® DF 2938 F (stab.) prevents air entrainment during mixing.



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.


  • High dosage robustness
  • Freeze-thaw resistance
  • Constant air content
