I. Scope of Application
Suitable for all steel structure components of various steel structure factories, logistics warehouses, and large venues, including roofs, walls, steel purlins, steel beams and columns, and color steel tile substrates; suitable for new steel structure coating and renovation and recoating of old steel structures, applicable to all climates in both the north and south.
II. Core Value
Steel structure roofs and walls: conduct heat quickly, resulting in hot summers and cold winters, high energy consumption for air conditioning and heating, and condensation due to temperature differences; long-term outdoor exposure easily leads to rust and corrosion, paint peeling, structural safety hazards, and high maintenance costs.
Using a special thermal insulation and anti-corrosion coating system: a one-stop solution to address the dual needs of steel structure anti-corrosion and rust prevention + roof and wall thermal insulation, while ensuring structural protection, constant temperature and energy saving, and long-lasting durability, reducing costs and increasing efficiency.
III. Core Performance
Temperature range: -40℃ ~ 150℃, resistant to high and low temperature changes, UV radiation, wind and rain erosion, and industrial atmospheric corrosion; the coating does not crack, powder, or peel off;
Thermal insulation and anti-corrosion: simultaneously achieves steel structure anti-corrosion and rust prevention + roof and wall thermal insulation;
Long-lasting anti-corrosion and structural protection: isolates moisture, acids, alkalis, and oxygen from corroding the substrate, preventing steel structure rusting and oxidation, extending the service life of the building, and reducing the frequency of future maintenance;
Constant temperature and energy saving: excellent thermal insulation properties, balancing indoor temperature differences, cooling in summer and retaining heat in winter, reducing air conditioning/heating energy consumption, preventing condensation and dampness, and significantly reducing overall energy consumption;
Strong adaptability: high adhesion, fits steel structures and color steel tile metal substrates, resistant to base layer deformation, and suitable for harsh industrial plant environments.
IV. Construction Process
1. Surface Treatment Before Construction
Remove rust from the base surface to Sa2.5/St3 level, remove rust, oil stains, and dust; the construction surface should be dry and free of standing water, and the environmental temperature and humidity should meet the standards. 2. Construction Procedure
① Primer Coat: Apply a special metal rust-removing and anti-corrosion primer, evenly applied by roller/spray, to seal and prevent rust and enhance adhesion;
② Main Coat: After the primer is completely dry, spray multiple coats of aerogel coating (2-3 coats); the thickness of each coat should not exceed 2mm;
③ Top Coat: Apply a weather-resistant topcoat to enhance weather resistance and scratch resistance, and unify the color;
④ Detail Protection: Thicken the coating at corners, beam-column joints, eaves, and rivet areas to prevent missed coatings and heat leakage.
3. Construction Key Points
For large areas, high-pressure airless spraying is recommended, with roller application for corners and edges; strictly apply thin coats in multiple layers, strictly control the application amount, and cure at room temperature for 7 days before use.
5. Comprehensive Core Benefits
Economic Benefits: Long-lasting thermal insulation reduces energy consumption costs, anti-corrosion and anti-deterioration reduce future maintenance costs, and the investment is quickly recovered;
Safety Benefits: Eliminates structural safety hazards caused by steel structure corrosion, and avoids mold damage to goods/equipment caused by condensation;
Practical Benefits: Comfortable indoor environment, improved working/use environment, weather-resistant and durable coating, no frequent maintenance required, and does not affect normal production and operation.
6. Quality Acceptance
Acceptance Standards: The coating is flat without missed coatings, sagging, or cracking, the adhesion meets the standards, the anti-corrosion and thermal insulation performance is effective, and the dry film thickness is uniform.
