1. Why Are Preservatives and Biocides Essential for Coatings?
1.1 The Risks of Microbial Contamination
Without preservatives and biocides for coatings, products can suffer from:
? Spoilage – Bacteria cause foul odors and viscosity issues.
? Mold Growth – Fungal contamination ruins surfaces.
? Algae Growth – Leads to discoloration and deterioration.
Using coating biocides ensures prolonged shelf life, enhanced performance, and microbial resistance.
2. Types of Preservatives and Biocides for Coatings
2.1 In-Can Preservatives (Wet-State Protection)
These coating preservatives prevent bacterial and fungal contamination during storage and production.
? Common In-Can Biocides:
2.2 Dry-Film Preservatives (Long-Term Protection)
Once coatings dry, exposure to moisture and UV rays can encourage mold and algae growth.
? Popular Dry-Film Biocides:
3. How to Choose the Right Preservatives and Biocides for Coatings?
