Silicone Defoamers - rapid foam breaking + long-lasting foam suppression

 Chemical Product and Company Identification

Product Name: Silicone-based Defoamer
English Name: Silicone Defoamer
Manufacturer: Qingdao Zhongshitiancheng Petrochemical Co., Ltd.
Product Application: This product is a highly efficient emulsion-type defoaming additive. It is primarily used in industries such as water treatment, coatings, papermaking, and industrial cleaning. It can rapidly eliminate and provide long-lasting suppression of foam generated during production processes, thereby ensuring process stability and product quality.

Core Performance Advantages

✅ Efficient foam elimination and suppression: With polydimethylsiloxane as the core active ingredient, it has extremely low surface tension, enabling rapid breakdown of foam in the system. It also effectively prevents foam reformation even at low concentrations (0.05%–0.5%).
✅ Excellent compatibility with systems: Specifically designed for aqueous systems, it is highly compatible with water and various industrial solutions. It does not cause layering or oil separation, and does not affect product transparency or subsequent processing properties.
✅ Wide range of applications: Stable under varying temperatures and pH levels, it can be used in conventional industrial conditions. Suitable for applications in water treatment, coatings, papermaking, industrial cleaning, and more.
✅ Safe and minimally irritating: It has low acute oral toxicity (LD50 > 5000 mg/kg in rats). It causes only mild irritation to skin and eyes. There is no risk of flammability or explosiveness, making it a safe choice for use.

Use Cases

Water treatment industry: Eliminate foam during the treatment of industrial wastewater, municipal sewage, biochemical aeration tanks, and landfill leachate, ensuring efficient treatment and stable equipment operation.

Paint industry: Remove bubbles from water-based paints, latex paints, and other coatings during production and application. This prevents defects like pinholes and fish-eye patterns in the coating, thereby improving the quality of the final film.

Papermaking industry: Reduce foam in pulp black liquor, white water, coating solutions, and wet processes in paper mills. This improves the filtrability of the pulp and enhances paper uniformity and production efficiency.

Industrial cleaning industry: Eliminate foam in metal cleaning solutions and other industrial cleaners to ensure effective cleaning results. Preventing foam from overflowing also helps maintain operational efficiency.

Stability and Waste Disposal

•Stability: Stable under normal temperature and pressure. Avoid contact with strong oxidizers, high-temperature environments, or freezing conditions to prevent emulsion breakdown or decomposition.
• Waste disposal: Dispose of as general industrial waste, in accordance with local environmental regulations. Do not discharge directly into water bodies or soil.

How to Use and Recommended Dosage

Addition Method:** It can be added directly or diluted 5–10 times with water before being added drop by drop or sprayed on. This helps ensure rapid and even dispersion.
Recommended Dosage:** Generally, 0.05%–0.5% of the total system volume is sufficient. The exact dosage should be determined through preliminary tests, taking into account factors such as foam strength, temperature, and pH value.
Optimal Timing for Addition:** It’s recommended to add it at the beginning of foam formation or during the production process. After addition, stir or circulate the mixture for 3–5 minutes to ensure thorough dispersion of the defoamer.
