Dalian, China — COMBAT (Dalian) Technology Co., Ltd., a leading Chinese specialty chemical manufacturer, has announced the full availability of its biocides specifically engineered for metalworking fluid preservation. The comprehensive product line delivers antimicrobial performance comparable to premium imported brands while offering significantly better cost efficiency, providing metalworking fluid formulators and end-users with a compelling domestic alternative.

A Complete Arsenal Against Microbial Contamination

The COMBAT series addresses the full spectrum of microbial threats in metalworking environments, covering soluble oil emulsions, semi-synthetic fluids, and fully synthetic cutting fluids. The portfolio spans multiple active ingredient classes to meet diverse formulation requirements:

Formaldehyde Releasers: COMBAT HMAE, B2, B7, MBM, and DMH provide rapid, broad-spectrum bacterial control with dosage rates ranging from 700 ppm to 4,000 ppm in diluted fluids. COMBAT HMAE features low skin sensitization and minimal irritation, while COMBAT MBM offers exceptional chemical stability with anti-corrosion protection for machining environments and emulsification of tramp hydraulic oil.

Isothiazolinone-Based Solutions: COMBAT BIT20, 753, 786, BV14, and 758 deliver formaldehyde-free preservation. COMBAT 753 achieves effective protection at remarkably low addition rates of 170–360 ppm, while COMBAT BV14 (Kathon-based) targets Pseudomonas bacteria with particular efficacy at 100–200 ppm.

Specialized Actives: COMBAT ZPT (sodium pyrithione) provides broad-spectrum, low-toxicity protection for fully synthetic concentrates at 150–400 ppm. COMBAT IP30 and IP10 (IPBC-based) offer powerful anti-mold performance for systems requiring fungicidal reinforcement.

Advanced Formulations: COMBAT K14Plus targets anaerobic bacteria responsible for fluid rancidity in sump-side applications, while COMBAT V698K4 and KM90 provide aluminum-specific and formaldehyde-free broad-spectrum solutions respectively.

Versatile Application Flexibility

The COMBAT series supports both concentrate formulation and field-side (sump-side) addition, with clear compatibility indicators for each product. Dosage recommendations are precisely calibrated for diluted working fluids, enabling formulators to optimize preservation economics without compromising efficacy.

Closing the Gap with Global Brands

"Metalworking fluid manufacturers have long faced a difficult choice between high-cost imported biocides and lower-performance domestic alternatives," said a COMBAT spokesperson. "COMBAT series closes that gap. Through rigorous quality control and advanced formulation expertise, we deliver antimicrobial efficacy, chemical stability, and operator safety profiles that meet or exceed international standards—at a fraction of the import cost."

The company's product specifications demonstrate equivalence to globally recognized actives including triazine derivatives, BIT, MBM, and IPBC, all manufactured under controlled conditions in Dalian.
