Powder defoamers are used to control unwanted foam and air in dry-mix formulations. For NOVASTAR grade selection, confirm the intended binder system and application, then evaluate air control alongside workability and the finished product’s performance requirements.
Before dosing, request the current grade-specific technical data sheet (TDS) and safety data sheet (SDS). Confirm the recommended trial range, whether it refers to supplied product or active content, and whether its mass basis is total dry mix, binder or another stated quantity. Do not transfer a dosage percentage between different calculation bases without conversion.
