Powder Defoamer
Powder defoamer (also called antifoaming powder) is a dry, free-flowing white or off-white powdery functional additive designed to eliminate existing foam and inhibit new foam generation in aqueous systems after hydration. The core working mechanism is to reduce the surface tension of liquid foam films, thin and rupture bubble walls rapidly, and block foam reformation for a long time. It is made for direct mixing into dry powder raw materials; when mixed with water, the encapsulated active ingredients disperse evenly to deliver stable foam control performance.

🌱 Core Advantages
- Convenient storage, transport and dosing
Powder form defoamers is easy to packaging, storage and transportation; compatible with automatic dry-mix feeding equipment, easy to weigh and blend uniformly with other powder additives without segregation.
- Efficient foam control with low dosage
Delivers fast defoaming speed and lasting foam suppression effect at tiny dosage; removes both visible large bubbles and hidden microfoams that cause surface pinholes and cracks.
- Wide formulation compatibility
Compatible with cellulose ethers, cement, gypsum, fillers, pigments and surfactants; Minimizing affects adhesion strength and surface gloss.
🧱 Key Applications
1. Dry-mix Construction Materials (Largest Application)
Cement-based products: Self-leveling mortar, tile adhesive, waterproof mortar, concrete repair mortar. Removes entrapped air bubbles to improve compactness, compressive strength and anti-cracking performance of finished concrete/mortar.
Gypsum systems: Wall putty, plaster, joint filler, gypsum board slurry. Eliminates foam during mixing to guarantee smooth, pinhole-free wall surfaces and stable setting time.
Dry powder coatings and Microcement products.
2. Coatings, Inks & Papermaking
Water-based dry powder paint, printing ink raw powder: Eliminates mixing foam to prevent pinholes and uneven coating layers.
Paper-making dry sizing powder, pulp processing additives: Reduces foam interference in pulp washing and coating stages, enhancing paper smoothness and printability.
3. Other Industrial Fields
Ceramic glaze powder: Removes mixing foam to avoid glaze pits and uneven firing surfaces.
Water treatment solid flocculant additives, chemical polymerization dry formulations, textile printing dry thickener systems.
