Purpose:
This standard specifies a laboratory test method to evaluate the fungal resistance of paints, varnishes, and coatings containing film preservatives.
Key Focus:
- Tests the effectiveness of preservatives in preventing fungal growth on coated surfaces.
- Simulates real-life conditions to assess long-term durability and protection against fungal attacks.
Test Procedure:
- Sample Preparation:
- Apply the coating with preservatives onto a suitable test panel and allow it to cure.
- Fungal Exposure:
- Expose the coated sample to a fungal spore suspension in a controlled environment.
- Evaluation:
- Observe the surface for fungal growth over a defined period.
- Assess the degree of discoloration or damage caused by fungi.
Applications:
- Interior and exterior coatings exposed to humid or damp environments.
- Paints used in bathrooms, kitchens, basements, or exterior walls.
- Ensures compliance with quality standards for mold-resistant coatings.
