iHeir-TQ is a new type of industrial anti-mold agent, can simultaneously anti-mold, anti-bacterial, anti-algae, is one of the most effective anti-bacterial agent in the industrial field. It is one of the most effective antimicrobial agents in the industrial field. It is more effective than other inorganic or organic systems that can only antimicrobial or only anti-mold.
To coordinate the contradiction between leveling and sagging, it is necessary to add a thickener with good rheological properties, that is, rheology modifier, to adjust the rheology of the coating and improve the leveling and sag resistance of the coating. The viscosity of the coating applied under high shear force is reduced to have good fluidity and leveling. After the construction is stopped, the wet film viscosity can return to a higher value in a short time, making the coating film Not easy to sag.
Water-based coatings also need to add a wetting agent to increase the wettability of the substrate and prevent shrinkage of the coating film. In addition to having a significant effect on the coating film wetting the substrate, the wetting agent can also balance the surface tension during the film formation process, improve the flow and leveling performance of the wet film, reduce or eliminate the Benard vortex, prevent floating, eaa copolymer dispersion Flowering phenomenon. In addition, adding some co-solvents to the water-based paint can increase the compatibility of the components in the system and extend the wet edge time of the coating film.
2. The role and classification of anti-cratering and leveling agents in water-based coatings
In view of the main coating film defects in water-based coatings, the following types of anti-cratering and leveling agents can be used to improve:
Wetting agent—reduce the surface tension of the coating, help the coating wet the substrate and prevent shrinkage of the coating film;
Leveling agent—Improve the flatness of the coating film surface and improve the smoothness of the coating film;
Rheology modifier—Improve leveling and sag resistance, and achieve the best balance between these two aspects;
Cosolvent-reduce the surface tension of the coating, increase the compatibility of the system, improve the flow and leveling.
