The appearance is white loose powder.
Under the action of visible light or ultraviolet light, it has redox ability and stable chemical properties. It can degrade harmful organic substances such as formaldehyde, toluene, xylene, ammonia, radon, TVOC, pollutants, odors, microorganisms and other harmful organic substances into harmless CO2 and H2O, and have the characteristics of pollutant removal, hydrophilicity, self-cleaning, etc., with long performance and no secondary pollution.
The precautions of the coating additives in the application process are further explained, so that the formula designer can fully consider the interaction between the components of the entire formulation, as well as the correct addition process and precautions for the use of the additives, so that the application of the additives will have a negative effect Minimize or controllable, and maximize the use purpose, advantages and additive effects of coating additives. Finally, according to the instructions on how to use additives when coating, baking, filming and correcting and remedying coating film defects, so that the end user of the coating film can obtain the highest satisfaction and evaluation. It is hoped that these can have a guiding reference for formulators who are developing new coating varieties, formulators who are new to coating formulations, and application engineers who are investigating original formulation additives, as well as for the selection of coating additives and the main reference evaluation. Put forward suggestions and methods. For the various additives mentioned in the article, you can refer to the relevant chapters of this book, or consult the corresponding suppliers for further information.
Main considerations for coating formulation design
Before introducing the application of coating additives in solvent-based coatings, let’s take a look at several main factors that affect coating formulations.
①We need to confirm the task and purpose of the paint, whether it is to provide protection, repair, coloring, decoration, barrier, or conductivity.
②According to the task and purpose, the degree of quality requirements should be achieved, for example, the following coating properties: gloss, hardness, adhesion, flexure resistance, weather resistance, and chemical resistance.
③Considering the paint production, painting environment and baking conditions, take these production, painting and curing conditions as reference elements for paint formulation design.
④It is necessary to consider the functionality of the coating in the coating, for example: whether it is used as a primer, patch, primer, color paint or finish, and even the compatibility, recoatability or repairability between coatings should be considered.
