General
Vinapor® DF 2922 F (stab.) is a powder defoamer based on a silicone-free blend of surface-active and mineral substances.
Vinapor® DF 2922 F (stab.) can improve the quality of dry mortars by reducing the air content and increasing the density. It is especially suited to reduce air entrainment during mixing for highly viscous mortars.
Vinapor® DF 2922 F (stab.) is highly compatible with pigments and fillers and prevents air entrainment during mixing.
Fields for application are e.g. self-levelling underlayments (SLU), non-shrink grouts, flowing floor screeds, joint grouts, repair mortars, dry-mix concrete, UHPC.
