------- XRT-DF
This high-temperature-resistant polyether defoamer is made from propylene glycol, glycerin, propylene oxide, and ethylene oxide, using potassium hydroxide as a catalyst. It delivers an excellent, long-lasting foam-inhibiting effect.
Eco-friendly and high-efficiency, this non-silicone antifoam agent can be mixed directly with water. Specially developed for concrete admixture, it offers excellent compatibility and perfectly complements polycarboxylate superplasticizers, serving as a premium modified higher-alcohol polyether ester defoamer for cement slurry and construction projects.
◆ Pre-use Preparation: Stir well before use, as sedimentation or stratification
May occur after long-term storage.
◆ Dosage: Add directly to the polycarboxylate superplasticizer at a
recommended dosage of 1–3‰ (based on the weight of the
superplasticizer). Mix thoroughly to form a homogeneous water-reducing
agent mixture.
◆ Application Tip: Stir the polycarboxylate superplasticizer for 20–50 seconds before use to ensure uniform dispersion.

◆ Concrete admixtures
Mixes well with polycarboxylate, naphthalene, lignosulfonate, and other water-reducers to get rid of foam made
during production, mixing, and pumping.
◆ Cement paste/mortars
Useful for cement paste, plaster, masonry mortar, and self-leveling screeds to reduce air bubbles and make the mix denser.
◆ Precast products
Used in making precast concrete items like panels, pile sections, wall panels, and floor tiles.
◆ On-site construction
Works in ready-mix plants, cast-in-place concrete, grouts, grout injectables, and waterproof slurries.
◆ Related chemical systems: Can be used as a defoamer/foam suppressor in water-based building additives, paints, and other
waterborne building emulsions.
Store in cool, dry conditions away from direct sunlight.
Agitate gently before each use to maintain consistency.
Avoid mixing with strong acids, bases, or incompatible chemical additives.

Traditional concrete wall construction faces a long-standing set of operational challenges. Labor-intensive steel mesh installation consistently slows down project timelines. Over time, moisture penetration creates severe spalling risks as internal steel begins to corrode.
Traditional secondary reinforcement relies heavily on welded wire mesh. This approach demands significant manual labor. It frequently suffers from improper placement on job sites. Worse, it rarely prevents early-stage plastic shrinkage cracking.
Rising costs of heavily polymer-modified asphalt (PMA) and Stress Absorbing Membrane Interlayers (SAMI) are forcing pavement engineers to seek alternative mechanical reinforcement strategies.
Uncontrolled foam in industrial processes doesn't just look messy. It causes severe equipment cavitation and significantly reduces usable tank capacity. It also slows down production throughput and introduces critical defects into finished products.
Modern highway and industrial road construction faces massive pressure. Project owners demand aggressively accelerated timelines. They also expect extended lifecycle durability from every pavement slab.
Concrete contractors and specifying engineers face mounting operational challenges today. Unpredictable steel costs frequently squeeze tight project margins. Placing traditional welded wire mesh demands intensive manual labor and slows down pour schedules.
The concrete reinforcement industry is undergoing a massive shift. Engineers and contractors are rapidly moving away from labor-intensive traditional steel like rebar and wire mesh. Advanced engineered polymers now offer a smarter, highly efficient alternative for modern builds.
Managing foam generation remains a massive hurdle in food, beverage, and packaging production. Excess foam severely reduces processing throughput. It causes messy spillovers on facility floors. You must control this rapid macrofoam expansion without violating strict food-contact safety regulations.
