Formulation design system for water based coatings - wetting leveling agent
The wetting leveling agent can effectively reduce the surface tension of the system and significantly improve the construction effect of the waterborne wood lacquer.After the addition of the wetting leveling agent, the wetting property and permeability of the paint increase, the leveling property of the paint liquid is improved, and sometimes the shrinkage (frame effect) problem can be overcome.More importantly, the leveling agent can solve the common shrinkage cavity problem, especially the shrinkage cavity caused by excessive use of the defoaming agent.Excessive leveling agent will offset the defoaming effect of the defoaming agent, so that the paint liquid will generate bubbles during construction, and some will have obvious foam stabilization effect. Therefore, it should be used with good leveling property, low foaming property and stable foaming. Small wet wetting leveling agent.The combination of leveling agent and defoamer, including the selection of varieties and the control of dosage, is the focus of research on waterborne wood lacquer formulations.
