Description
Two-component solvent borne misture curing Inorganic Ethyl Zinc silicate coating.
Recommended Use
This primer gives the best protection from corrosion to abrasive blasted steel. It is recommended for exterior and interior of water and storage tanks (based on the material stored inside), structures, bullets, equipments of petrochemical complex, refineries, fertilizer units, power plants, steel plants, smelters, cement plants, paper and pulp plants,transportationindustries, chemical plants, etc., Inorganic zinc silicate provides cathodic protection to steel and gives excellent corrosion resistance even in the most severe conditions, when used in a suitable system

Surface Preperation
Abrasive blasting to min Sa 2 1/2 Swedish specifications is must with a blasting profile of 45 – 70 microns. The surface should be absolutely dry, oil and salt free before application of the primer. The primer should be applied preferably immediately or withing 4 hours after blasting for best performance. Incase it is extended; the surface should be cleaned by sweep blast to remove any flush rust that may have formed.
Application Data
MIXING RATIO : Part A : Part B – As per our recommendationsAPPLICATION : By Conventional Spray / By Airless Spray
THINNER : Type 004
POT LIFE : 4 hours min at 30® C
RECOMMENDED DFT : 60 – 75 µ.
OVERCOATING INTERVAL : Min. : 24 hours (If relative humidity is more than 65%) Max.: Indefinite
(Surface should be free from Zn corrosion products & other impurities)
COMPATIBILITY : Compatible with Epoxy, PU, Chlorinated Rubber and Heat Resistant paints.
Application Method
Open the packing just before use. Take the liquid part in a clean container and add zinc dust gradually by wieght into it, as per the recommended ratio, under slow constant power stirring. Stir the mix gently to attain homogeneity. Add thinner Type 004 into the mix and stir gently for few minutes. Strain the mixture through 60-80 mesh screen and apply uniformlyover the surface. All the equipments used for above should be properly clean. Stirring should continue till the batch is completed. Brush application is not recommended. If ralative humidity is less than 40%, it is advisable to sprinkle water over the primed surface after about 30 minutes of application.
Application Data
MIXING RATIO : Base : Hardener – (As per our recommendations)APPLICATION : By Brush / By Conventional / By Airless Spray
THINNER : Type 001
POT LIFE : 3 hours min at 30® C
RECOMMENDED DFT : 30-40 µ.
OVERCOATING INTERVAL : Min. : 8 hours
Max. : 24 hours
COMPATIBILITY : Can be applied over Epoxy and Polyurethane primers, intermediated coats and topcoats synthetic enamel paints.
Application Method
Stir the Base part thoroughly. Mix the base and hardener as per our recommended ratio by volume. Stir the mix gently to attain homogeneity. Add thinner type 001 into the mix, if required depending on the application method and then stir gently for few minutes. Allow the mixture to stand still (maturation) for about 10-15 minutes to initiate the reaction. Strain the paint through Nylon filter cloth 400 mesh size and apply uniformly over the surface. All equipments used for above should be properly clean.
Application : By Conventional Spray / By Airless Spray
When over coating with H B paints apply by mist coat/full coat technique.

Notes
1. Do not apply paint when temperature falls below 10® C or rises above 50® C when Relative Humidity is above 85% & during rain, fog or mist. Surface temperature must always be minimum of 3 ® C above Dew point.
2. Spray equipment should be cleaned with KP’s recommended thinner otherwise equipment is liable to be damaged.
3. Products with various % of metallic Zinc contents are available on request.
4. Shelf life indicated is minimum for this Prodcut in sealed conditions and it is subject to re-inspection thereafter. Individual component is required to be stored in cool, dry and covered condition away from heat and ignition.
5. Shake the liquid part thoroughly before adding zinc dust into it. Do not open the packing until just before use. Avoid moisture contact with the zinc dust.
Health & Safety
This is a solvent based paint and care should be taken to avoid inhalation of spray or eyes. Mist or vapours as well as
contact between the wet paint and exposed skin.
