Audited Supplier 1. Green environmental protection, anti-static, extremely low VOC, free of heavy metals, and no odor during use, meeting the food hygiene quality requirements.
2. With matte and beautiful appearance; Antibacterial and bacteriostatic; Easy to clean and maintain.
3. The chemical hybrid composite between high-performance polyurethane and high-strength cement silica sand results in a coating that is resistant to damage, has toughness when subjected to impact/deformation, and does not cause cracks or delamination.
4. Resistant to various organic acids, bases, amines, salts, and solvents.
5. The coefficient of thermal expansion is similar to that of concrete. During normal thermal cycles, the coating and the concrete substrate do not exhibit displacement differences, delamination, or cracking, and maintain their physical properties within the temperature range of - 5 ºC to 50 ºC.
6. Fast solidification speed and short construction period.
Base Surface Treatment
The treatment of base concrete is the key to making a good polyurethane concrete floor. The quality of ground treatment directly affects the service life of the floor. In order to enhance the adhesion between the base and the floor, mechanical treatment is required to expose concrete aggregates (such as shot blasting). The floor surface must be grooved, with the depth and width of the groove being 2-3 times the thickness of the polyurethane mortar floor; In particular, all edges (such as trenches, etc.) should be grooved at a distance of 20mm;
Primer Application
After the base surface is cleaned, mix the SPR-23101P polyurethane universal self-leveling mortar material evenly according to the design ratio, pour another bucket for mixing again, and then use the scraping and coating method for batch scraping construction. Strictly control the filling of each groove and gap. After mixing the material, use a trowel to continuously pave it. This step cannot be interrupted, and needs to be completed as soon as possible to ensure good adhesion of the material. To ensure that the base layer is completely sealed, a polyurethane primer of 1 mm is suitable.
Laying Copper foil
: After curing the polyurethane mortar primer, paste the copper foil on the primer according to the design requirements (generally 3 m * 3 m);
Construction Of Water-based Conductive Primer
Evenly mix SPR-21105ESD water-based epoxy resin anti-static primer according to the proportion, pour another bucket for mixing again, and evenly roll it onto the ground with a roller. It is required that there is no holiday. After curing, measure its resistance. Generally, the measured resistance should be less than 10 to the fifth power;
Surface Coating Construction
Mix the SPR-23106ESD polyurethane anti-static self-leveling mortar according to the proportion (using a low-speed double-head or spiral blade mixer), pour another bucket and mix it again. Use a nail rake to evenly spread the material according to a certain thickness, use a trowel to level it, and use a defoaming roller to roll back and forth. After the material is mixed, continue coating. This step must be completed as quickly as possible to ensure good surface effect and adhesion.
Processing areas with high requirements for chemical corrosion, areas with high requirements for electrostatic conductivity and the need to control electrostatic current, chemical processing, solvent storage and processing workshops, communication products, large precision instruments, and other fields.
