In the production process of water-based polyurethane to add a certain type of additives, it is necessary to pay attention to its role in the various stages of storage, construction, application, and consider and evaluate its role and impact in the next section. For example, when the water-based polyurethane paint is operated with wetting and dispersing agents, it plays a certain role in storage and construction, and it is also good for the color of the paint film. There is usually a dominant effect, and at the same time cause a series of simultaneous positive effects, such as the use of silicon dioxide, there is a extinction effect, and the absorption of water, surface anti-adhesion and other positive effects. In addition, in the use of a certain agent may have a negative effect, such as the addition of silicon-containing defoaming agent, its defoaming effect is significant, can get an effective positive effect, but also to evaluate whether there is a shrinkage hole, is not cloudy, does not affect the recoating and so on. All in all, the application of additives is, in the final analysis, a practical process, and the only criterion for evaluation should be the quality of the application results.

Sinograce Chemical produces a variety of water-based additives,Coatings Additives include wetting agent, defoaming agent, slip agent, thickener, dispersing agents, flow and levelling agents etc. The additives improve product properties and eliminate or reduce problems occurring during formulating surface coatings systems, thus optimizing production processes.
