ARCOSET PU-9K is a chemical resistant coating based on Poly Urethanes which play a very important role to fight against corrosion and erosion. Never before have so much thought, R & D works, gone in curbing corrosion with a film of a few microns thickness.

ARCOSET PU-9K is a high strength, high build PU coating which is the result of the specific research and development towards this direction. With this, we are now able to supply high quality anti - corrosion coatings, which guarantee the value of steel structures for many years.

ARCOSET PU-9K is specially formulated PU systems to impart highly cross linked films whereas the conventional urethanes give a linear, non resistant film. The formulation is stoichiometrically adjusted to give optimum combination of toughness and flexibility. The film is quite tough, yet sufficiently resilient to withstand normal expansion and contraction of the substrate without cracking up. The film bonds firmly to a variety of substrates such as metal, wood, concrete, etc. and this quality together with resilience makes ARCOSET PU-9K more suitable for protective uses than the conventional systems. They are safe bet for corrosive environments where the epoxy coatings would not stand up because of certain acids' presence, and where a polyester would fail due to extreme alkalinity.

 
ARCOSET PU-9K has the following general properties :

• Excellent UV resistance
• Excellent adhesion and durability.
  
• High abrasion resistance.
  
• Chemical & water resistance.
  
• Weather resistance.
  
• Heat resistance - resistance to temp from + 150°C to -25°C.
  
• Acid & Alkali resistance.
  
• High fungi and mildew resistance
• Anti funal properties

Surface preparation:

Prepare the surface upto Sa 21/2 specification so as to attain a surface free of oil, dust, rust and previous coats. To attain such a surface, rust and previous coats are to be removed by manual methods like scrapping, chipping, hard wire brushing, emery papering, etc. Sand blasting may be adopted wherever necessary so as to attain a surface up to the minimum standard of 2nd quality of BS : 4232 - 1967. Oil and grease are removed by solvents. Chemical treatments may also be adopted so as to remove traces of rust by using phosphating chemicals, rust converters, etc.

Enviromental conditions:
Relative humidity <85%. Atmospheric temp. >15°C

Cleaning Solvent:
APUC - 1

Thinner:
APUC - 1
