3. Applications & Recommended Use Levels

• Suitable Applications:

  • Water-based paints and emulsions

  • Wood coatings and stains

  • Decorative and architectural coatings

  • Industrial dry-film finishes

• Typical Use Levels:

  • 0.6% – 4.0% w/w in the final formulation, depending on the severity of exposure and required longevity

4. Mechanism of Action

• Active Ingredient: Diuron
  A photosystem II (PSII) inhibitor that blocks photosynthetic electron transport in algal cells. This effectively disrupts growth and colonization on treated surfaces, delivering long-lasting protection in outdoor or humid environments.

5. Stability & Handling

• Shelf Stability: Maintains efficacy across a wide pH range (4–12) and resists degradation up to 100 °C

• Storage: Keep in sealed containers, in cool and shaded areas. Avoid freezing and direct sunlight.

• Handling Instructions:

  • Stir well before use to ensure uniform dispersion

  • Integrate thoroughly during the formulation process

  • Follow general safety measures for handling biocides

6. Safety & Regulatory Guidelines

As a Diuron-based algicide, GuardExo® DN 50 should be handled in accordance with standard chemical safety protocols:

• Use PPE (gloves, safety glasses, masks)

• Avoid prolonged skin contact or inhalation

• Follow local disposal regulations for biocidal compounds

• Ensure labeling and formulation compliance as per BPR, EPA, or local jurisdiction
