Features and benefits
Rosner Thinner used in conjunction with Rosner Solvent Based products to dilute the products. Thinners are mixtures of organic solvents of different chemical composition. The type of organic solvents and the proportion in the mixture are dependent on the intended purpose. The term “thinner“ is generally used in paint industry although some solvent mixtures have other specific properties than just thinning the paint.
