------XRT-DP
Our silicone powder defoamer is professionally formulated to deliver outstanding antifoam and long-lasting foam suppression across industrial applications. The product combines strong defoaming power with excellent antifoaming persistence and stability.
A key advantage is its versatility: this general-purpose silicone antifoam effectively controls and eliminates foam in water-based systems and some water‑oil mixes. Supplied as a powder, the active silicone is evenly dispersed on a solid carrier for easy dosing into your system.
This special formula overcomes common limitations of traditional silicone emulsion defoamers: emulsion-based defoamers can fail in high‑electrolyte, extreme-pH, or high‑shear emulsification conditions, where active ingredients quickly coagulate and lose effectiveness. Our silicone powder defoamer remains stable and effective under these harsh conditions, making it ideal for demanding concrete admixtures, industrial processes, and other tough applications.

◆ Concentration Requirements
The amount of defoamer required varies depending on the specific
application. However, to ensure optimal performance, it is
recommended that the content of silicone actives in the system is not less
than 10 ppm.
◆ Application Methods:
Direct Application: When used directly on - site, the defoamer can be
spread directly onto the surface of the foam to initiate the
defoaming process. This method is simple and effective, especially for
small - scale foam control or in situations where quick action is needed.
◆ Dissolved in Water: Another option is to dissolve the defoamer in water first and then sprinkle the solution onto the
foam surface. This approach allows for more uniform distribution of the defoamer, which can be beneficial for larger
areas or more complex foam structures.

1. Q: Surface defects with silicone—how to avoid?
A: Use the correct grade and dosing, ensure good dispersion, avoid overdosage, and run trial panels for colored/self-leveling
finishes.
2. Q: How fast does silicone emulsion act, and how long does the effect last?
A: Silicone emulsions act within minutes under mixing and typically maintain defoaming through mixing and early setting.
Persistence depends on formulation and system.
3. Q: Storage, shelf life, and handling tips?
A: Store sealed in cool, frost-free conditions away from direct sun. Typical shelf life 6–18 months depending on formulation—check
label. Use PPE per MSDS.

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.
