Double protection inside the tank + paint film | Water-based anti-corrosion coating-specific bactericide
I. Microbial Growth Challenges of Water-Based Anti-corrosion Coatings
Water-based anti-corrosion coatings use water as the solvent, and have a high organic content of emulsions and additives. After storage in the tank and formation of the coating film, they are prone to bacterial, yeast, mold, and sulfate-reducing bacteria growth. They are a high-risk category in the coatings industry, presenting four prominent production and usage pain points:
Tank deterioration and loss due to spoilage: During storage, the coatings develop an odor, expand, decrease in viscosity, and separate and break down the emulsion. The entire barrel of coatings is scrapped, increasing production costs.
Mold growth on the coating film reduces protection: Outdoor steel structures, water engineering facilities, and factory base materials with coating films get damp and develop mold and peeling, weakening the anti-corrosion adhesion and accelerating the rusting of the base materials.
Poor compatibility with common additives: Ordinary bactericides that break down the emulsion in the coating system affect the gloss of the coating film, cause color change and color variation, and reduce the anti-corrosion salt spray performance.
Limited compliance with environmental protection: Traditional water-based anti-corrosion coatings containing formaldehyde and high VOC bactericides do not meet the national standards for industrial water-based coatings and cannot be used in green municipal and heavy industry projects.
II. Special Solution for Bactericide of Dalian Tianwei Water-based Anti-corrosion Coatings
Dalian Tianwei has been deeply engaged in the field of anti-bacterial and anti-corrosion coatings. Leveraging its years of research experience in water-based systems, it has specifically developed dedicated bactericides for water-based epoxy, water-based acrylic, and water-based alkyd full-system anti-corrosion coatings, taking into account both tank internal anti-corrosion and coating film anti-mold effects. It is suitable for all production processes such as feeding, mixing, and grinding, providing a one-stop solution for microbial problems throughout the coating storage, construction, and film formation cycle.
III. Five Core Advantages of the Product
System compatibility, no change in paint film properties: Compatible with a wide pH range of 4-11, suitable for various water-based anti-corrosion emulsions, without demulsification, no color floating, does not affect the hardness, adhesion and salt spray anti-corrosion performance of the paint film, and does not affect the color matching of the topcoat.
Bidirectional broad-spectrum antibacterial: Composed of a slow-release formula, highly effective in killing gas-producing bacteria and yeast in the tank, long-term inhibition of mold and algae growth on outdoor paint films, avoiding microbial drug resistance, dual effect of tank protection and paint film protection.
Green and environmentally friendly compliance: No formaldehyde, low VOC, no heavy metals, mild odor, in line with industrial water-based paint environmental testing standards, suitable for outdoor heavy industry, municipal engineering, and indoor equipment anti-corrosion scenarios.
Good water solubility, suitable for mass production: Water-based liquid additives, can be dispersed by dilution, can be ground and added, added after paint mixing, suitable for automated coating production lines, small addition amount, rapid and uniform mixing.
High stability in weathering and water resistance: Resistant to high and low temperatures, resistant to rain erosion, after film formation, antibacterial components lock the internal structure of the paint film, the paint film's antibacterial protection is not easily lost or decomposed in outdoor high-temperature and low-temperature environments, the antibacterial protection of the paint film is stable and long-lasting.
IV. Application Scope
Water-based epoxy anti-corrosion paint, water-based acrylic industrial anti-corrosion paint
Water-based alkyd rust preventive paint, water-based topcoat and basecoat integrated anti-corrosion coating
Special water-based anti-corrosion topcoat and primer for steel structures, pipelines, water engineering facilities, and industrial water-based rusting pastes, water-based anti-corrosion supporting emulsion system
V. Tips for Use
1. Addition method: Can be added during the grinding of pigments or during the final paint mixing stage;
2. Regular addition amount: 0.15%-0.3% of the total weight of the coating, for high-temperature and high-humidity storage and outdoor conditions, the addition amount can be increased to 0.4%;
3. Compatibility suggestions: Avoid direct mixing of strong alkaline high-concentration additives, regular water-based systems can be directly mixed;
4. Storage: Store in a sealed and cool place, prevent freezing, the stability of the original liquid storage is excellent.
