Preserve What’s Visible – Surface Protection That Lasts Beyond the Final Coat
Dry film preservatives are specialized antimicrobial agents designed to provide long-term protection to cured coatings and other surface-applied products. Once a product like paint, plaster, adhesive, or sealant has been applied and dried, its exposed surface becomes vulnerable to colonization by microorganisms such as mold, mildew, algae, and bacteria. These contaminants not only degrade the appearance of the coated surface but also compromise the structural integrity and performance of the product over time.
Dry film preservatives work by incorporating slow-releasing or surface-active biocidal ingredients into the formulation. These agents remain dormant within the dried film until microbial activity begins or moisture levels rise, triggering the biocide to act. This approach ensures proactive and reactive protection, allowing the product to maintain its visual appeal, durability, and hygienic safety even under extreme conditions.
Used across industries that rely on durable, exterior-grade, or moisture-exposed coatings, dry film preservatives have become indispensable for ensuring that finished products not only perform on day one—but also resist environmental degradation for years.

Where Are Dry Film Preservatives Used?
Architectural Coatings
Used in exterior wall paints, façade finishes, and interior ceiling coatings to prevent black mold, mildew, and green algae staining. They ensure walls stay clean and visually consistent for the life of the product.
Construction Chemicals
Essential in plaster, grout, mortars, skim coats, and ready-mix powders that harden into surfaces constantly exposed to moisture and air. These materials are particularly susceptible to surface-level fungal growth.
Adhesives & Sealants
Silicone, acrylic, and PU-based sealants applied around windows, sinks, and joints are prone to microbial growth due to frequent condensation and trapped organic material. Dry film preservatives help prevent the tell-tale black stains in corners and cracks.
Wood Coatings & Outdoor Finishes
Used in stains, lacquers, and protective coatings for fences, decks, sheds, and garden furniture. Prevents biofilm development caused by rainwater, shaded areas, and soil contact.
Hygiene-Critical Spaces
Wall and ceiling paints in bathrooms, food-processing areas, hospitals, and clean rooms need added microbial resistance to maintain hygiene and regulatory compliance.
Marine & Industrial Coatings
Dry film biocides protect structural steel, ship hulls, and portside infrastructure coatings against green algae, mold, and fungal growth in salty, wet, and UV-exposed environments.
