Anti-corrosion and mold-prevention solution for latex paint cans: Microbial protection throughout the entire production-to-use cycle

02-09-2026

Latex paint is the most widely used category of architectural coatings, widely applied for interior and exterior wall decoration. However, the formula of latex paint contains a large amount of organic components such as water, cellulose, thickening agents, and emulsions, and throughout its production to usage cycle, it faces two types of microbial threats: bacterial contamination in the tank leading to odor, layering, and deterioration of the barrel; mold growth on the coating film causing black spots, moldy patches, and color fading on the wall surface.


Research has confirmed that it is necessary to select an appropriate amount of tank-in-antiseptic and dry film anti-mold and anti-algae agents simultaneously. The two are highly complementary and compatible, ensuring the quality of the paint throughout its entire life cycle. Tianshi Blue Shield has launched a "tank-in-antiseptic + dry film anti-mold" dual-effect solution specifically for the latex paint system. With a core focus on broad-spectrum efficiency, system compatibility, and safety and environmental protection, it builds a complete microbial defense line from the production end to the usage end.


01 Why does latex paint need "dual protection"

Tank-in-bacterial contamination: Invisible production loss

In the storage tanks and packaging barrels of latex paint, bacteria and yeast can rapidly multiply, causing the paint to stink, pH to drop, viscosity to fluctuate, and layering and deterioration. Tank-in-antiseptics can only inhibit the growth of bacteria and molds and are ineffective against algae. Therefore, a specialized tank-in-antiseptic solution is needed.


Dry film mold growth: Invisible threat after application

After the latex paint coating film is cured, in humid environments (basements, kitchens, bathrooms, rainy seasons on exterior walls), black Aspergillus, green mold, etc. can grow on the coating surface, forming black spots and moldy patches, and in severe cases, causing the coating film to flake off and fall off. Dry film fungicides can kill molds and algae but are ineffective against bacteria. Special configuration is required.


Why do we need "dual effect combination"

The action targets and protection stages of tank-in-antiseptics and dry film anti-mold agents are different, and they are highly complementary. Only by using them together can the quality of latex paint from production to usage be ensured throughout the entire cycle. A single solution cannot cover all microbial risks over the entire cycle.


Dalian Tianwei Chemical Co., Ltd. Tank-in-antiseptic solution

Dalian Tianwei Chemical's tank-in-antiseptic is a water-based, VOC-free multi-active component compound fungicide designed specifically for long-term tank-in anti-corrosion protection of water-based coatings.


Broad-spectrum fungicidal, low concentration highly efficient

LD09C combines multiple active components, mutually compensating for the fungicidal spectrum, and can effectively control the growth of bacteria and fungi at a low concentration. The microbial resistance risk is minimized. It is suitable for latex paint, silica fume plaster, etc., high-humidity formula systems, preventing odor and deterioration during storage.

Excellent system compatibility

It achieves high compatibility in water-based coating systems, without damaging the adhesion, color stability, and rheological properties of the coating. It is applicable in a pH range of 4-10, meeting the needs of various water-based coating formulas.


VOC-free, safe and environmentally friendly

The product is a water-based,VOC-free formula,with good stability, in line with the trend of green coating production. The recommended addition amount is generally 0.1%-0.3%, which can be added during the mixing stage.
