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

            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 adhesion, chemical and heat resistance, good to excellent  mechanical properties and very good electrical insulating properties. Almost any property can be  modified.
  • Epoxies are polymer materials that begin life as liquids and are converted to the solid polymers  by a chemical reaction. An epoxy based polymers having mechanically strong properties.

Properties of PU based coating
  • High abrasion resistance.
  • High resistance to chemical.
  • Wide range of flexibility combine with toughness.
  • Excellent combination of high gloss.

Why to choose epoxy floors?
There are many reasons why to go for epoxy flooring, as being seamless in  nature, hygienic properties, slip resistance etc.

Impact Resistance: Epoxy floors are generally used in areas of industry where goods are  handled in specific spaces, such as production lines, warehouses, loading bays, and where  compressive loads are generated by the movement of goods on trucks, pallets etc.

Slip Resistance: Pedestrian traffic areas require varying degrees of slip resistance dependent  on whether the environment is wet or dry.

Fire Resistance: Fire escape routes, explosive production and storage areas underground car  park decks.

Hygiene: Pharmaceutical, Automotive, food, beverage, chemical and electronics industries  have very demanding sanitary requirements. These industries often need totally dust free and  easily cleanable floors, without cracks or angled Corners.

Chemical Resistant: Epoxy floor coverings provide an impermeable seal to protect floor from  chemical attack.

Classification of Floor coating
light duty flooring 
light duty flooring is use generally for chemical resistance , light abrasives and more attention toward aesthetics and clean ability.







Medium duty flooring 
Medium duty flooring is generally use for chemical resistance to harsh chemicals, foot traffic resistance , rubberized wheel movement resistance.







High duty  flooring 
High duty flooring used where maximum abrasion resistance required, resistance to cast iron wheel and hot concentrated chemicals.






System of Floor Coating


















Pot Life : When fully mixed, approximately 30-40 minutes @ 20 degree C. Extended pot life at lower temperatures, reduced at high temperatures.

Curing Time: Initial cure after 24 hours @ 20 degree C. Do not use at temperatures below freezing. 

Foot Traffic in 24 hrs Heavy Traffic after 48hrs Full cure in 7 days.

Chemical Resistance: Resistant to spillages of many chemicals commonly met within industry. Contact Technical Services for more advice.

Storage: All the components Resin, Hardener & Filler must be kept in cool, dry place and in covered shed. 

Health & Safety: It is advisable to wear protective wears at the time of use of Epoxy Screed and all other products used. In case of contact with eyes and skin, wash with plenty of water and consult a doctor.
