Broad-spectrum efficacy against bacteria, fungi, and algae in industrial water systems.
Stable performance across a wide pH range (pH 4–9) and tolerant to common water treatment additives.
Low-dosage efficiency—effective at concentrations as low as 50–200 ppm depending on system conditions.
Non-oxidizing chemistry minimizes corrosion risk to carbon steel, stainless steel, and copper alloys.
Compatible with common scale inhibitors, dispersants, and other biocide programs for synergistic control.
Cooling water systems in power generation and HVAC applications.
Process water circuits in pulp & paper manufacturing.
Recirculating water systems in chemical and petrochemical plants.
Make-up water and closed-loop systems requiring long-term microbial control.
Industrial wastewater treatment units where biofilm prevention is critical.

Q1: What is the primary mode of action of Lonzagard CP-100 Biocide?
A: Lonzagard CP-100 Biocide functions as a broad-spectrum preservative through controlled release of active biocidal components, primarily targeting bacteria, yeasts, and molds by disrupting essential cellular processes such as membrane integrity and metabolic activity.
Q2: In which types of industrial formulations is Lonzagard CP-100 typically used?
A: It is commonly incorporated into water-based industrial products including metalworking fluids, latex paints, adhesives, construction chemicals, and cleaning concentrates—where long-term microbial stability and compatibility with anionic and nonionic systems are required.
Q3: How should Lonzagard CP-100 be dosed in a formulation?
A: Dosage depends on formulation composition, pH, temperature, and anticipated microbial challenge; it is typically used at low concentrations, generally ranging from 0.1% to 2% by weight, with optimal performance achieved when added during the final stage of manufacturing under mild agitation.
Q4: Is Lonzagard CP-100 compatible with common surfactants and thickeners?
A: Yes, it demonstrates good compatibility with a wide range of anionic, nonionic, and amphoteric surfactants, as well as common rheology modifiers such as hydroxyethyl cellulose and associative thickeners—though compatibility testing under actual formulation conditions is recommended prior to full-scale implementation.
Q5: What storage conditions are recommended to maintain product efficacy?
A: Store in original tightly sealed containers at temperatures between 5°C and 30°C, protected from direct sunlight and excessive humidity; avoid freezing, as prolonged exposure to low temperatures may affect physical stability and subsequent dispersion performance.
