Corrosion
By Dr E. Ramanathan, Paint Consultant Chemistry of Corrosion Corrosion is a natural process that involves the deterioration of materials, typically metals, due to chemical reactions with their environment. The theory of corrosion is essential for understanding and preventing this phenomenon. Several theories and mechanisms explain the corrosion process, with the most widely accepted ones…
Mills used in acrylic emulsion paints
When manufacturing acrylic emulsion paint, the choice of mill is crucial to ensure the proper dispersion of pigments and the stability of the emulsion. Here are the suitable mills for making acrylic emulsion paint: 2. High-Speed Disperser (HSD): 3. Three-Roll Mill: 4. Attritor Mill: 4. Basket Mill: When selecting a mill for acrylic emulsion paint…
Manufacture of airless spray paint bottles
Aerosol spray paints are manufactured through a multi-step process that involves mixing and filling. 1. **Formulation**: This is the first step, which involves mixing pigments, solvents, and resins to create the paint. The pigments provide the color, the solvents make the paint sprayable, and the resins help the paint adhere to the surface. This mixture…

How to determine the coating weight of zinc phosphate coating
by Dr E Ramanathan Generally, thickness of different types of phosphate coating is reported as coating weight. Weight per unit surface area of phosphate coatings is calculated as follows: The coated specimen is weighed to the nearest mg (w1); the coating is removed by immersing the coated specimen in a 50 g/L chromic acid stripping…
