ELECTRODEPOSITION COATINGS history- why Electro-deposition- types of Electro-deposition- comparative study of CED and AED

Image
ELECTRODEPOSITION COATINGS Electro-priming of motor vehicle began in the late 1960s & within few years almost all mass-produced vehicles in industrialised countries were primed in this manner. The main reason for the universal and rapid acceptance of this process despite its higher initial installation, running & material costs were: Uniform film thickness in the range of      15-35 µ Greater operating flexibility Superior mechanical & corrosion performance properties Greatly reduced solvent emission & hazard Highly efficient with upto 95%of the coating material being utilised. Until mid 1970s all the electro primers used by the automotive industry were of the anodic type & resin systems included maleinised oils, polyesters, epoxy ester, or poly-butadiene polymers combined with specific anticorrosive pigments.                                   Now company's also d...

What is floor coating- use of epoxy and PU resin in floor coating- classification of floor coating

Image
            FLOOR COATING                   It is coating on different floor surfaces to protect them. There are different types of floor coatings, among them is the epoxy floor coating  which is widely used on : Industrial floors Pharmaceutical industries Warehouses Food & Brewages Residential Garage Basement floors Restaurants & even office facilities. Requirement of floor coating Heavy traffic Clean ability  Slip resistance Harsh chemicals Heavy foot traffic Vibration of machinery Thermal shock Light reflectivity Impact Microbial control Why Epoxy and PU based coating? Properties of epoxy based coating strong, chemically resistant to degradation of the chemical elements in the solid form and highly adhesive during conversion  from liquid to solid. There are a wide range of basic epoxy chemicals from which an epoxy  system can be formulated. Epoxies are known for their excellent adhe...
