Solvent Red 24 Definition & Guide: How to Use This Top Solvent Dyes for Paint Dyes Formulation
What Is Solvent Red 24
Basic Information Among the general Solvent Dyes, Solvent Red 24 is classical azo type present also as Sudan IV oil soluble red powder Solvent Dye. It is not a water soluble dye, but is soluble in organic solvents making it suitable for use as dye for oil based paints, varnishes and transparent lacquers. High tinting strength due to its bluish scarlet colour, high colour intensity in liquid paint systems is achieved with very low dosages for obtaining saturated red tones. As a general purpose industrial colorant, precipitation problems associated with inorganic pigments are avoided.
The ReasonWhy Solvent Red 24 Is The Best-Selling Paint Dyes
There are two main advantages of Solvent Red 24 over other Solvent Dyes which the formulators are looking for. Since it has stable light fastness (Rated 5-6) and heat resistance of 180°C, the paint film won't fade in indoor lighting. Excellent solubility in xylene,hence “ready to use” mixed with paint or resin; good solubility in butyl acetate and ethanol; easy to disperse into paint without grinding, saving manufacturing cost of paint factories. Such transparent tinting properties are ideal for clear wood coatings or metal finishing paints.
Solvent Red 24 And Coatings Some Helpful Tips To get the best performance from Solvent Red 24 as Paint dyes observe simple guidelines
Protocol Step 1: Pre-dissolve the powder in warm solvent (40-50℃) and then add to paint base and stir well to remove particles undissolved. Step 2: Maintain a dosage of between 0.02% and 0.06% for clear coatings to maintain the clarity. Do not mix with water-based resin systems with Solvent Dyes such as Solvent Red 24 which are not soluble in aqueous solutions. Sample small batches to match target red shade for uniform mass production.
Main Industrial Applications of Solvent Red 24
Solvent Red 24 Applications in Industry According to the National Industrial Chemicals Notification and Assessment Scheme (NICNAS) SRA report, Solvent Red 24 is utilized primarily in the following industries: paint or dyes for the automotive and aviation industries and toys. Solvent Dyes variant has a wide range of applications other than paint dyes. It is used to color clear plastic, oil lubricants in machine marking, printing inks and candle wax. For coaters, colorant purity Solvent Red 24 is still the preferred transparent red colourant for furniture varnish, metal anti-rust oil paint and hobby aerosol paints, offering a compromise between colour brightness and long term colour stability in end-products.
