Industry Overview
Protecting Coatings from Microbial Degradation
Coating formulations and coated surfaces may face microbial risks during raw material handling,
production, storage, application, and end use.
Waterborne coatings generally require particular attention to microbial control because moisture and organic
components can support microbial growth. Depending on the formulation and end use, protection may involve in-
can preservation to help control microbial spoilage before application and dry-film protection to help reduce mold
growth on the cured surface. Product selection should also consider coating performance, appearance, and
formulation compatibility.
Industry Challenges
Common Coating Protection Challenges
In-Can Spoilage & Microbial Deterioration
Waterborne paints are susceptible to bacterial and fungal growth in the container, potentially causing changes in viscosity, pH, odor, and overall product stability.
Dry-Film Mold Growth
Cured coating films exposed to humid or contamination-prone environments may develop mold growth, leading to staining, discoloration, and surface quality concerns.
Raw Material Contamination
Raw materials, process water, production equipment, and certain formulation components can introduce or support microbial contamination, increasing the need for appropriate formulation and process control.
Risk Scenarios
Microbial Risk Stages Across the Coating Lifecycle
Different stages of production, storage, application, and use create distinct microbial threats.
Our solutions can be selected and evaluated according to the specific risk stage,
coating formulation, and target protection requirements.
01 — PRODUCTION & RAW MATERIALS
Raw Material and In-Line Contamination
During raw material handling and production, process water, equipment, airborne contamination, and formulation components can introduce microorganisms into waterborne coating systems.
Key Risk: Uncontrolled microbial contamination may contribute to spoilage and inconsistent product quality.
02 — IN-CAN STORAGE
Open-Container Spoilage & Odor
After a container is opened, repeated exposure to the surrounding environment can increase the risk of contamination. Waterborne coatings may require effective preservation throughout storage and use, particularly when formulation conditions support microbial growth.
Key Risk: Microbial growth may cause odor, viscosity changes, or reduced product stability when preservation is inadequate.
03 — APPLICATION & CURING
Surface Contamination During Film Formation
During application and drying, wet films may be exposed to airborne spores and environmental contamination. Humid or poorly ventilated conditions can extend drying time and increase surface exposure to moisture.
Key Risk: Surface contamination during film formation can increase the risk of visible mold growth or surface quality issues in suitable environments.
04 — DRY-FILM & END USE
Mold Growth on Cured Coatings
Once the coating is cured and in service, long-term exposure to humidity, surface contamination, and suitable nutrients can increase the risk of mold growth in moisture-prone environments.
Key Risk: Mold growth on dry films can cause staining, discoloration, and surface quality concerns.
A STRUCTURED APPROACH TO COATING PROTECTION
1. Raw Material Control
Assess raw material quality, process conditions, and potential contamination sources before production.
2. In-Can Preservation
Select suitable in-can preservatives according to the formulation, target shelf life, and applicable requirements.
3. Dry-Film Protection
Select suitable dry-film protection for coating applications exposed to mold-prone service environments.
4. Compatibility Verification
Verify compatibility with the resin system and formulation to help maintain coating performance and appearance.
