What are the effects of talcum powder on water-based paint

With the continuous progress of society and the tremendous improvement of technology, the development and application of the efficacy and function of talc powder have been deepened, and its use in various industries has also been widely adopted. In recent years, the strict requirements of energy-saving and emission reduction policies and the progress of consumer awareness have brought new opportunities for the future development of water-based coatings. Although traditional coatings still have a large market share, water-based coatings are the direction of the coating industry. Liaoning talc powder

Due to the layered molecular structure of talc powder, it can be uniformly layered and dispersed in the resin when used in coatings, exhibiting good compatibility and mechanical complementarity with the resin. Just like the steel reinforcement mesh embedded in concrete, it can not only adhere to the advantages of the coating itself, but also form a mechanically excellent reinforced support structure, improving the physical function of the product.

For water-based paints, for topcoats that require high gloss and transparency, talcum powder can be added without or with minimal amounts. However, for primers, talcum powder or other fillers may not be sufficient to utilize its sealing properties. Generally, the dosage is between 5% and 20%.

Due to its inactive chemical properties, as well as its resistance to acid and alkali, talc powder added to coatings can also reduce aging, weathering, and improve electrical properties. As talc powder has a sheet-like structure, it increases the dispersion path of corrosive substances in the paint film, thereby improving the protective effect.
