As a key additive in coating systems, leveling agents work based on precise control of liquid surface tension and flow behavior. Chemi Tech leveling agents achieve dynamic surface tension balance during coating curing process through unique chemical structure design, effectively eliminating surface defects such as orange peel and shrinkage.
Surface tension gradient elimination: By migrating molecules to the coating surface, local surface tension differences are reduced, promoting uniform liquid spreading
Optimization of leveling process: Adjust the viscoelasticity of the system, extend the opening time, and ensure that the coating is fully leveled before curing
Interface defect repair: Directed adsorption on micro concave areas of the substrate to improve wettability and prevent the formation of pinholes and volcanic craters
The special polysiloxane modification technology of Chemi Tech leveling agent can maintain stable compatibility in resin systems of different polarities. The functional groups in its molecular chain segments can dynamically adjust their arrangement according to the curing process of the coating: quickly migrate to the interface to reduce surface tension in the early stage of construction, maintain moderate fluidity in the middle stage of curing, and finally achieve molecular ordered arrangement in the film formation stage, avoiding affecting the coating gloss and adhesion.
Chemi Tech has developed leveling agents with gradient surface activity for high solid content systems. Through the synergistic effect of multiple functional groups, a tension gradient is formed in the thickness direction of the coating, driving the fluid to flow from the high tension zone to the low tension zone, which is particularly suitable for complex construction scenarios such as vertical surface spraying. Laboratory test data shows that adding 0.3% -0.8% Chemi Tech leveling agent can reduce the surface roughness of the coating by 62% and increase glossiness by more than 35%.
