Inorganic Zinc Silicate Primer

Product Description : A high performance primer to provide corrosion protection to blasted steel substrates in highly corrosive environments, e.g., onshore and offshore steelworks, pipelines, bridges etc. A post fabrication primer for long-term protection prior to subsequent overcoating in the field. Fast drying primer. Able to withstand surface dry heat temperature of up to 400°C-600°C..

  • Solvent based ethyl silicate pigmented with zinc powder.
  • Fast drying primer with outstanding anti-corrosive protection.
  • Will withstand surface temperatures up to 400°C-600°C PHYSICAL CHARACTERISTICS.

DRYING TIME: Touch Dry-10 mins, Hard Dry- 6 Hrs

DFT: 45-50 Micron

COVERAGE AREA: 8sq.mtr per litr

FINISH: Matt

NO. OF COMPONENTS: Two (Hydrolysate 10LTR + Zinc dust 10LTR)

Mixing Ratio: 1:1

SURFACE PREPARATION:
  • Remove all wax, oil and grease by solvent cleaning in accordance
  • Where necessary remove weld spatter and round off all rough weld seams and sharp edges to a smooth surface.
  • Any surface defects revealed by blast cleaning should be ground, filled or treated in a suitable manner.
  • An average surface profile of 50 microns is acceptable, but this average should not exceed 75 microns.
  • After blasting, remove dust from the surface.
  • The surface to be coated must also be clean and dry. Before over coating this product ensure that the surface is clean, dry and free from zinc salts.
  • If the surface shows sign of breakdown, a sweep blast may be necessary

METHOD OF APPLICATION: Airless Spray, Roller or By brush

This is the recommended method of application: Maximum 5% Thinner may be added. Stir liquid converter thoroughly and add powder. Continue stirring until thoroughly mixed. Filter through a 30 to 60 mesh screen to remove any large particles before use. The continuously mixed material should be applied by spray. When application is made by Merchandise conventional spray, use the lowest air pressure that will achieve good atomization in order to minimize overspray. Apply the material in one wet coat, overlapping each pass 50% and holding the spray gun at right angles to the surface at all times. The spray gun should be held approximately 8 inches (20cm) from the surface, using a 6 to 8 inch (l5-20cm) fan. When application is made by airless spray, use an inbound pressure approximately 10 psi above the level at which "pig-tails" occurs. Hose length should be limited to not more than 20 meters.

Application Conditions Do not apply this product if the Relative Humidity exceeds 85% or if the substrate temperature is within 3°C of the dew point.

The Inorganic Zinc Silicate Primer is a high-performance, solvent-based primer designed to provide superior corrosion protection for steel surfaces. It contains a high percentage of zinc dust, offering excellent adhesion and durability. This primer is ideal for use in harsh environments, including marine and industrial settings, and can be applied using conventional or airless spray techniques. It provides a tough, abrasion-resistant finish that withstands extreme weather conditions and high temperatures.
