Coatings are usually divided into solvent based coatings and water based coatings, the biggest difference of which is the different dispersion medium. Solvent based coating is based on organic solvent, while water-based coating is based on water. Obviously, water is easier to obtain, and is more clean and environmental friendly than organic solvent, so more and more people use water-based coating for home decoration.
Main difference between water based coatings and solvent based coatings
1. Different glossiness of coating filmDue to the dilution of water, the glossiness of water-soluble coating is easy to volatilize, so the glossiness of film-forming is poor; while the glossiness of solvent based coating can achieve the effect of high gloss, mainly because it can control the coating by resin, which can not reverse the coarseness and realize the evaporation of glossiness. 2. The different color of coating filmThe choices for the pigments for water-based coatings is relatively less and not enough for rich colors description; while the choices for the pigments for solvent based coatings are many and are sufficient for rich colors presentation. 3. The difference of construction viscosity of coatingWater-based coatings are difficult for viscosity due to the nature of water itself, while solvent based coatings are more convenient. 4. The difference between resin and diluent in coatingsThe reason why water-based coatings are called water-based is that they are water-soluble. Water-soluble coatings can be diluted in proportion, while solvent based coatings can only be diluted by organic solvents.
