Applications of Metasol DGH in Industrial Manufacturing

Metasol DGH, a high-performance biocide and preservative, supports consistent production quality and compliance for manufacturers in a select range of industrial processes where microbial contamination poses critical risks. Below, we provide an in-depth view of its established use in four industrial sectors, detailing required compliance systems, typical input levels, integration points, and representative finished product categories.

1. Water-Based Paint and Coating Preservation

Industrial paint and coating producers rely on Metasol DGH as a trusted preservative to protect aqueous formulations against bacterial and fungal spoilage during storage and application. Major coating lines for architectural, industrial, and automotive applications depend on its efficacy to reduce batch rejections and extend shelf stability without compromising environmental or worker safety requirements. Its application demands careful integration at the pigment dispersion or post-mill addition stage to maintain dispersion integrity and avoid adverse interactions with pigment and additive systems.

Industry compliance standards

• European Biocidal Products Regulation (BPR, Regulation EU 528/2012)
• US EPA Antimicrobial Registration for paints and coatings (FIFRA)
• ASTM D2574 microbial resistance testing
• ISO 9001:2015 QC system implementation for batch manufacturing

Typical usage ratio

• 0.05–0.20% w/w based on total paint mass, adjusted for fungus and bacteria levels, storage conditions, and local climate impact.

Downstream process integration

• Metered addition post-primary dispersion at low to moderate shear, or inline dosing prior to packaging; manufacturers monitor biocide addition in QC to avoid under- or overdosing.

Final product types

• Architectural waterborne wall paints
• Industrial water-based resin coatings
• Automotive OEM waterborne primers
• Acrylic and latex-based construction surface coatings

2. Metalworking Fluids Preservation

Metal cutting, forming, and grinding fluids require reliable antimicrobial protection to prevent fluid spoilage, minimize operator exposure to hazardous microbes, and reduce overall maintenance costs. Fluid compounders utilize Metasol DGH for both in-tank preservation and end-use extension in water-miscible metalworking fluid concentrates. Addition must be tailored to the fluid formulation (borate-based, semi-synthetic, or synthetic), with monitoring for compatibility with surfactants and lubricity enhancers.

Industry compliance standards

• REACH Regulation (EC 1907/2006) for formulated lubricants and cutting fluids
• US EPA Antimicrobial Product Registration (FIFRA)
• German TRGS 611 (Technical Rules for Hazardous Substances – metalworking fluids)
• ISO 6743/7: Metalworking fluids–Classification and specifications

Typical usage ratio

• 0.10–0.30% w/w in concentrate; adjusted in end-use dilution to maintain 50–200 ppm active in machine sumps, depending on fluid change frequency and circulation volume.

Downstream process integration

• Added directly into the concentrate batch at blending; periodically dosed into working systems during scheduled fluid maintenance intervals according to microbial status guided by dip-slide or ATP tests.

Final product types

• Water-miscible metalworking coolants
• Semi-synthetic and synthetic machining fluids
• Grinding and honing lubricants
• Corrosion-inhibiting aqueous fluids for part washing or temporary storage

3. Adhesives and Sealants Preservation

Producers of water-based adhesives and sealants apply Metasol DGH to protect emulsion polymers, natural and synthetic latex systems, and starch-based adhesives during production and shelf storage. Microbial contamination in these matrices can deteriorate viscosity and bonding performance, rendering affected batches unsalable. Formulators must introduce the preservative typically after polymerization but prior to addition of thickening agents, with regular stability trials to assess any impact on open time or cure profile.

Industry compliance standards

• EU Biocidal Products Regulation (BPR, EU 528/2012)
• FDA 21 CFR 175.105 (for adhesives with possible indirect food contact, in applicable systems)
• ISO 14675 Microbiological testing in adhesives
• GB 18583-2008 (Chinese Mandatory Requirements for Hazardous Substances in Adhesives)

Typical usage ratio

• 0.08–0.15% w/w, set according to water activity and raw material sensitivity; increased for formulations with natural polymers.

Downstream process integration

• Blended into the cooled base polymer or resin after high-temperature processing, before final viscosity adjustment and packaging. In-line static mixers ensure uniform distribution in bulk containers.

Final product types

• Water-based construction adhesives
• Acrylic sealants for construction joints
• Labeling and packaging glues (non-food contact)
• Latex carpet adhesives and binders

4. Household and Institutional Cleaning Product Formulation

Formulators of ready-to-use and concentrated liquid detergents, surface cleaners, and disinfectants use Metasol DGH to safeguard aqueous cleaning systems from microbial spoilage during production and distribution. Its compatibility with anionic and nonionic surfactant systems allows dosing just after main ingredient dissolution or during final dilution stages. Regular micro and chemical stability tests ensure regulatory limits are maintained, especially for products with claims of long storage or multi-surface use.

Industry compliance standards

• US EPA Safer Choice and FIFRA labeling for antimicrobial action
• EU Detergents Regulation (EC No 648/2004)
• REACH Annex XVII restrictions compliance
• ISO 11930: Evaluation of the antimicrobial protection of liquid formulations

Typical usage ratio

• 0.03–0.12% w/w, increased for high water-activity formulations or in geographies with higher ambient storage temperatures.

Downstream process integration

• Added after surfactant dissolution and prior to fragrance/flavor batching, using low-shear mixing to prevent foaming and assure preservative efficacy; monitored through post-production micro testing.

Final product types

• All-purpose liquid household cleaners
• Concentrated institutional disinfectants (non-medical)
• Industrial kitchen cleaning agents
• Wipe solution concentrates for pre-moistened cleaning cloths
