Dr E. Ramanathan PhD Degreasing plants — whether batch-type, conveyorized, or fully automated — face several engineering problems that can affect productivity, safety, cleaning quality, and compliance. Below is a structured list of common engineering issues along with causes and remedies, tailored for plants handling metal cleaning with aqueous (alkaline or neutral) degreasers. 
Common…

Dr E. Ramanathan PhD Definition:Sedimentation is the settling of heavier pigments or extenders at the bottom of the paint container during storage, leading to separation, non-uniform consistency, and poor application properties. Causes of Sedimentation Remedies Note: Sedimentation is reversible if soft settling occurs. Irreversible “hard settling” may lead to product rejection.
Dfifferences between interior and exterior acrylic emulsion paints.
Dr E. Ramanathan PhD In this article the role and importance of hydroxyl (OH) value in acrylic resins across various types of acrylic paint formulations, focusing on how it impacts properties like crosslinking, durability, and application performance in water-based, solvent-based, thermoplastic, and thermoset systems.I’ll provide a comparative overview with detailed insights into each formulation type….

Dr E. Ramanathan PhD 1. What is trication phosphating? Trication phosphating is a metal surface treatment process that deposits a crystalline phosphate layer using three metal cations—zinc (Zn²⁺), nickel (Ni²⁺), and manganese (Mn²⁺)—to improve corrosion resistance and paint adhesion. 2. What are the advantages of trication phosphating over zinc phosphating? 3. What type of substrates…
Chain-stopper alkyd paints offer several advantages over conventional air-drying alkyd paints, primarily due to the use of monofunctional acids (like benzoic acid) that cap polymer chain ends and limit molecular weight growth.
