Core Product Advantages of FC-1620 (Specially for Coating Systems)
Excellent Wetting and Leveling Performance to Eliminate Coating Film Defects
Pure water systems have a surface tension as high as 72 dynes. When applied on substrates with low surface energy or construction surfaces contaminated with slight oil stains, coating defects such as edge shrinkage, craters, volcano pinholes and uneven spreading tend to occur easily.
FC-1620 features ultra-high surface activity. A very low dosage can greatly reduce the surface tension of the system, rapidly improve the wetting and spreading capacity of paint liquid on substrate surfaces, effectively avoid various construction defects, deliver smooth and uniform coating films, and significantly enhance the film-forming texture and finished product qualification rate of coatings.
Powerful Water and Oil Repellency to Improve Water and Solvent Resistance of Coating Films
Compared with solvent-based coatings, conventional water-based coating films suffer from long-standing drawbacks including poor water resistance, high permeability and weak solvent resistance.
After adding FC-1620, fluorocarbon molecules will evenly accumulate on the surface layer of the coating film to form a dense and stable water-oil repellent protective film. It can effectively block the penetration of water molecules and boasts outstanding solvent resistance, fundamentally improving the water resistance, stain resistance and corrosion resistance of water-based coating films.
Dual Anti-staining Property to Meet Anti-fouling Requirements in All Scenarios
Daily stains are divided into hydrophilic stains and lipophilic stains. Conventional additives only provide single protection: ordinary hydrophilic coating films cannot resist water stains, while hydrophobic coating films fail to withstand oil stains.
The unique fluorocarbon chain structure of FC-1620 delivers both hydrophobic and lipophobic properties, which can repel all kinds of hydrophilic and lipophilic stains simultaneously. It endows coating films with long-term anti-staining and easy-to-clean characteristics, greatly extending the service life of coatings.
Superior Thermal Stability Suitable for High-temperature Baking Processes
Most ordinary surfactants on the market have poor heat resistance. They are prone to decomposition and failure under high-temperature baking conditions, generating bubbles and impairing coating film performance.
FC-1620 exhibits excellent temperature resistance and can stably withstand high-temperature baking at 150℃–200℃. It will not decompose or lose efficacy under high-temperature processes, and steadily performs wetting, leveling and protective functions throughout the process, making it perfectly compatible with the production and construction of various water-based baking coatings.
Improved Anti-blocking Performance of Coating Films for Emulsion Systems
Mainstream water-based systems such as styrene-acrylic emulsions commonly face problems including soft coating films, slow drying speed and poor anti-blocking performance. Skin sticking and film peeling frequently happen when finished products are stacked or attached to each other.
A tiny dosage of FC-1620 can effectively optimize the surface structure of coating films, increase the dryness and anti-blocking capacity of coatings, eliminate blocking defects of finished water-based coatings, and improve the storage and application stability of products.
Auxiliary Enhancement of Substrate Adhesion
Benefiting from its powerful substrate wetting capacity, FC-1620 enables the wet film of water-based coatings to fully penetrate and adhere to substrate surfaces, eliminating interfacial voids and helping improve the adhesion between coatings and substrates. (Adhesion mainly depends on the resin system; this product serves as an auxiliary efficiency enhancer.)
