The selection of cleaning pre film agents should be determined based on specific application needs and material characteristics. Here are some common types of cleaning pre film agents for your reference:
Fluorocarbon containing pre coating agents: These pre coating agents typically contain fluoride and carbon alkyl groups, which can form a low surface energy coating and have excellent anti fouling and corrosion resistance. Suitable for materials such as metal, glass, and ceramics.
Titanium phosphate pre coating agent: Titanium phosphate pre coating agent can form a very thin layer of titanium phosphate coating, providing good adhesion and corrosion resistance. Commonly used for surface treatment of aluminum materials to improve their coating performance.
Chromic acid passivation pre coating agent: Chromic acid passivation can form a dense and corrosion-resistant chromium compound layer, improving the weather resistance and adhesion of metal surfaces. Suitable for materials such as aluminum plating, zinc plating, and stainless steel.
Silicon modified pre coating agent: Pre coating agents containing silicon modified components can provide good wear and corrosion resistance, and can be used for surface treatment of metals, plastics, and other materials.
Acid cleaning purification agent: Acid cleaning purification agent can remove impurities such as oxides, grease, and dirt from metal surfaces, and provide a clean surface for subsequent coating or film formation processes. Common acid cleaning agents include sulfuric acid, hydrochloric acid, phosphoric acid, etc.
When selecting cleaning pre film agents, it is recommended to consider the following factors:
Material type and surface characteristics
Required film thickness and performance requirements
Process conditions and environmental requirements
Safety and environmental friendliness
Cost effectiveness
The best choice of cleaning pre film agent should be evaluated and tested based on specific circumstances, and follow relevant industry standards and specifications.
