In view of the fact that common floor coatings are difficult to meet the strict requirements for high-cleanliness places in GMP specifications, Taishi Product Research Center has developed Self-leveling epoxy topcoat, which is based on 100% solid content of special epoxy resin. It has excellent characteristics such as green environmental protection, gloss, one-time film-forming, strong, tough and wear-resistant paint film. It is an ideal floor coating system for electronic factory building and pharmaceutical factory building with high cleanliness.
Application Range
Aerospace, aviation and other places with high particularity of dust-free and sterile.
GMP Pharmaceutical Factory, Hospital, Blood Products and other aseptic rooms, precision machinery, microelectronics manufacturing plant, mechanical and chemical areas which with high requirements of comprehensive performance.
Product performance
Surface smoothness, beauty and mirror effect
Solvent-free, odorless, pollution-free and non-toxic
It has the properties of acid, alkali and chemical resistance.
Good resistance to moisture, salt spray, oil and organic solvents
Wear resistance, pressure resistance, impact resistance, high temperature resistance, waterproof, with certain elasticity
One-time forming of surface construction is fast and convenient

Process name | Specific practices and requirements | Reference dosage |
Primer layer | 1:Use high solid content epoxy primer, mix the main paint and curing agent proportionally, mix evenly. 2:Roll the coating with a roller to be uniform, no leakage. 3:Use a brush to brush the side of the door, the corner of the wall, under-chassis, etc | 0.12-0.2kg/㎡ |
Mortar layer | Use high solid content epoxy medium paint ,mix the main paint and curing agent proportionally and add 40-150 mesh quartz sand to mix evenly. 2:Scrape 1-3 times with batch knife. 3:After solidification, grind the defect such as knife marks and clean them up. | 0.5-0.7kg/㎡/mm |
Putty layer | 1: Use high solid content epoxy medium paint, mix the main paint and curing agent proportionally and add appropriate fillers (such as quartz powder, talc powder) to mix evenly. 2: Scrape 1-2 times with batches of knives, with emphasis on filling holes in the ground. 3: After solidification, grind the defect such as knife marks and clean them up. | 0.12-0.2kg/㎡ |
Closed layer | 1: Use high solid content epoxy surface paint, mix proportionally and mix evenly. 2: Closed leveling with batch knife. | 0.1-0.2kg/㎡ |
Surface layer | 1: Use high solid epoxy self-flowing flat paint, mix the main paint and curing agent proportionally, mix evenly. 2: Self-leveling the surface with prepared trowel or spraying with an airless gun. | 0.8-0.9kg/㎡/mm |
