StenMix® DEFOAMER is a polyetherester-based defoamer used in fresh concrete and employed in the production of concrete admixtures. Its high-speed air release enables concrete with low air content, low permeability and high strength.
Areas of Use
StenMix® DEFOAMER is used in the production of all types of concrete admixtures. It is compatible with numerous polycarboxylate, lignosulfonate and naphthalene sulfonate raw materials — particularly polycarboxylates branded SN Flux® — and is specifically designed for producing superplasticizers from these raw materials.
When added to such admixtures it reduces the air-retention capacity of concrete. Used at the correct dosage in neutral-pH mixtures it provides stable, non-separating air defoaming, and it can be combined with acetylenic defoamers or TIBP where very low air content is required.
