Techspray DF-1 Defoaming Agent, 1 Pint Bottle

Techspray Defoamer DF-1 Defoaming Agent – 1 Pint (473 mL) – P/N 1555-P – Inline & Batch Cleaning Systems

High-Performance Foam Control for Aqueous PCB Cleaning, Defluxing & SMT Stencil Cleaning Equipment

Techspray Defoamer DF-1 (P/N 1555-P) is a high-performance defoaming agent formulated to reduce excessive foam in water-based industrial cleaning systems. Designed for use in inline and batch defluxing equipment, spray-in-air batch stencil cleaners, and submersion cleaning systems, DF-1 helps maintain efficient cleaning operations while extending the useful life of cleaning baths.

As aqueous cleaning solutions become loaded with flux residues and other contaminants, excessive foaming can interfere with normal processing. Techspray DF-1 provides effective foam control across processing temperatures, helping reduce foam buildup without requiring premature replacement of the cleaning solution.

Featuring a silicone-free, particulate-free, and nonflammable formulation, Defoamer DF-1 is suitable for electronics manufacturing environments where maintaining cleaning process performance is essential. It can be added directly to the cleaning system sump or diluted with deionized (DI) water for targeted foam reduction.
