Oil-based epoxy resin: easy to prepare high solid-soluble solvent-free coatings, thick, high overall strength. Oil-based epoxy faults: odor, high humidity under construction conditions, visible paint fog side, temperature below 10 degrees Celsius is not easy to curing dry coatings. Water-based epoxy resin: water-based epoxy coating technology in recent years Not only is it environmentally friendly and non-toxic, but also it has excellent properties. It can be cured and dried as usual even at low temperatures. Most of the waterborne epoxy resins are not colorful and will not be affected by the surface humidity.
Determine the base strength, flatness and moisture content of the substrate: cement strength should be at least C20 (in frosting, ground strength should be strengthened with coating); normal surface flatness should be within 5mm (pits should be rounded). D solvent-free epoxy coating and quartz sand, high ground grinding should be erased when the base surface polishing. 基材含水量在6%以下,一般不超过10%,油性环氧材料的施工必须注意这一点,当施工时,当它潮湿时,没有粘附层的涂层,将剥离一层与地面,如果水性环氧涂料,只要无明水可确保地面,有一定的水分,不影响性能.
The moisture content of the base material is below 6%, generally not more than 10%. This must be paid attention to in the construction of oily epoxy materials. When the construction is done, when it is wet, there is no adhesive layer of the coating, it will peel off one layer and the ground. If the waterborne epoxy coating, as long as there is no clear water to ensure the ground, there is a certain amount of moisture, and does not affect the performance.
Ground grinding: polishing the entire floor to a certain degree of roughness with the diamond grinding head to improve adhesion between the coating and the ground. In the case of diamond, granulation and sandblasting are required, or direct use of high adhesive materials, such as solvent-free epoxy primers or water-based epoxy primers. Clean the dust after the ground.
