I. Performance of Low Surface Preparation Epoxy Coatings Low surface preparation coatings are high-performance paints particularly suitable for surfaces where gloss and color retention are not critical, and where sandblasting or shot blasting is difficult or impossible, allowing only manual or power tool rust removal. They can tolerate ST2 level surface preparation and are commonly used for the maintenance of anti-corrosion coatings on steel. They can also be applied to various substrates, including aged coatings, galvanized layers, and steel surfaces treated with blasting or water jetting. These coatings can be used alone, offer strong corrosion resistance, excellent mechanical properties, and can be applied in high film thicknesses.

II. Low Surface Preparation Epoxy Coatings As a high-quality product widely used in industrial corrosion protection, low surface preparation coatings are especially suitable for steel corrosion protection where surface preparation is challenging. Their main advantages lie in their superior performance in corrosion resistance, weather resistance, environmental friendliness, and application properties. Additionally, low surface preparation coatings hold certain advantages over other anti-corrosion products.

III. Applications of Low Surface Preparation Epoxy Coatings Low surface preparation epoxy coatings are widely used in the field of steel structure painting. They are suitable for steel structures where color and gloss requirements are not high. The excellent anti-corrosion properties of these coatings make them ideal for maintaining steel anti-corrosion coatings. They can also be applied to various substrates, including aged coatings, galvanized layers, and steel surfaces treated with blasting or water jetting. They provide corrosion protection for industrial, coastal, pulp and paper mill, bridge, and offshore facilities in both atmospheric and aquatic environments.

IV. Application Process of Low Surface Preparation Epoxy Coatings1. Substrate Preparation: The steel substrate surface should be free of dust, rust, oil, scale, and other attachments. Depending on the usage environment, different rust removal standards must be met. Low surface preparation epoxy coatings can tolerate ST2 level. 2. Coating Preparation 2.1 Stirring: Thoroughly stir the coating to ensure uniform consistency between the upper and lower layers, with no sediment or lumps. 2.2 Viscosity Adjustment: Use a dedicated thinner to dilute the coating to the working viscosity: brushing viscosity is 20-25S; spraying viscosity is 18-22S. 3. Coating Application: Apply the coating by spraying or brushing onto the prepared substrate surface. 4. Inspection: Check if the surface preparation meets the application requirements. Inspect the thickness and integrity of the coating layer. The surface should be complete, uniform, and free of missed areas. The thickness should meet requirements, with no other defects. 5. Precautions 5.1 Use a dedicated thinner for diluting the coating; do not substitute with other thinners. 5.2 Plan the amount based on the coating area to avoid waste. 5.3 Maintain a dry and clean environment during application. 5.4 Mix the coating and curing agent in the required ratio before use. Prepare only the amount needed, stir thoroughly, and apply.
