Qulite· HD531-SLF is a low-foaming surfactant developed specifically for industrial cleaning. The product adopts the over-branch chain position hindrance effect, which greatly increases the instability of the foam film, so the product has excellent low foam performance and outstanding rapid bubble breaking performance, leaving no residual bubbles. At the same time, the product uses the synergistic effect of optimized surfactants to have excellent oil stain stripping ability and outstanding oil removal performance. The product does not contain any form of defoamer, is acid-base compatible, and is suitable for industrial spray cleaning and other low-foam cleaning fields.
