Resistance Guide

Chemical Resistance
Exposures Splash & Spillage Mild Fumes/Outdoor Resistance
Acid Very Good Very Good
Alkalis Very Good Very Good

Salt Excellent Excellent
Water Excellent Excellent

 

Temperature Resistance :

  • Continuous- 93˚C
  • Intermittent- 120˚C

Weatherability : Good (chalks)
Flexibility :  Good
Abrasion Resistance : Very Good

 

Storage Life : Up to 6 month in intact condition or sealed the containers are kept under cover in a dry place under normal temperature conditions.

 

Surface Preparation :

Concrete : new concrete- ensures that the concrete is cured for a minimum of 3 months. The surface is to be made rough & free from laitance & other contaminants by sand sweeping.
 

Old concrete : Removes all salt deposits from the surface by water jet washing. Light sand blast the surface to remove all loosely bound coating & roughening up to firmly adhering coating to ensure anchorage with recommended system. Ensure all dust/ other particles are fully removed by suction or air blast & the surface is fully cleaned & dry before application of paint.
In non-critical areas where blasting is not possible, water jet washing & hard wire brushing are minimum requisites.

 

Steel : remove grease, oil & other contaminants preferably by using degreasing solvent. Blast clean to a minimum of Sa2 ½ Swedish st. SIS 05 5900. For severe corrosion, blast to Sa 3 with a surface profile not exceeding 65 microns.
If blasting is not practical, make full use of mechanical tools along with manual chipping & wire brushing to remove lose rust & scale to St 2 Swedish std. SIS 05 5900. Excessive burning of steel is to be avoided. Thoroughly dust down all surfaces. Best results can be achieved if the manually cleaned surface is primed with protectomastic- self-priming surface tolerant coating; otherwise, treatment with metal conditioning solution will also produce satisfactory results.
The surface should be clean & dry before application of Coal tar.

 

Application : Stir base thoroughly & then mix 3 parts of base & 1 part of catalyst by volume to uniform consistency. Allow the mixture to mature for 30 minutes & stir again before application & during use.

  • Brush / Roller : apply preferably without thinning. However if required during application add up to 5% thinner
  • Airless spray : apply preferably without thinning. However, up to 5% thinner may be added if absolutely essential depending on conditions. Use any standard equipment having pump ratio 40:1. Tip size 0.48-0.68mm.Tip pressure 110-160 Kg/cm2 .

 

Note :

  • Use off the mixed paint within the specified pot life period.
  • Do not apply when temperature falls below 10˚C or rises above 50˚C & when relative humidity rises above 90%. Do not apply during rain Fog or mist.
  • Brushes & spray equipment should be cleaned with thinner otherwise, equipment is liable to be damaged.
