Faraday Cage Effect in Powder Coating
Faraday Cage Effect in Powder Coating: In powder coating, the Faraday Cage Effect occurs when trying to coat recessed or complex-shaped areas (like corners, grooves, or cavities). These areas act like a Faraday cage, resisting electrostatic attraction of the charged powder particles. Cause: Problems: Remedies: This effect is a key consideration in quality powder coating…
Common Engineering Problems in Spray Degreasing Plants
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.

Sedimentation in Paints
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.
The Importance of OH value in acrylic resins and its impact in formulations of various types of acrylic 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….

Chain Stopper Alkyd Based Paint System
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.
