Description

Antifoam Pe-L is a high-performance, silicone-based defoaming agent designed for demanding industrial processes. It effectively controls and eliminates foam in aqueous and non-aqueous systems, ensuring operational efficiency and product quality. This product is essential for manufacturers in sectors such as wastewater treatment, chemical processing, adhesives, and coatings where persistent foam can disrupt production and increase costs.

Application

• Wastewater Treatment: Controls foam in aeration basins, digesters, and effluent streams.
• Chemical Manufacturing: Suppresses foam in reaction vessels, distillation columns, and during product transfer.
• Adhesives & Sealants: Prevents foam formation during mixing, compounding, and application processes.
• Paints & Coatings: Eliminates entrapped air and foam for a smooth, defect-free film.
• Pulp and Paper Production: Manages foam in pulping, bleaching, and paper coating operations.
• Textile Processing: Used in dyeing and finishing baths to prevent foam-related issues.
• Food Processing (Industrial Grade): Controls foam in fermentation, washing, and processing lines (subject to specific regulatory compliance).
• Metalworking Fluids: Defoamer for coolants and lubricants used in machining and grinding.
