STAR Gel is stain-free and does not impart yellow or black stains after washing with water. Moreover, it does not necessarily demand separate Passivation chemical process.
Area Coverage per kg: Approximately 90 to 100 meters of weld seam
1.) Remove dirt and oil using STAR 100 degreaser. Add 50-75 gm/litres in water (1kg STAR 100 in 15-20 litres water), stir and dissolve. Apply liquid STAR 100 Degreaser onto the surface for 5-10 minutes. Then rinse the surface thoroughly with water.
(Step 1 & 5 can be avoided for STAR Gel on weld seam application)
2.) Apply STAR Gel on the weld seams and surrounding areas with a nylon plastic brush.
3.) Leave the STAR Gel on the weld seams areas for 20-45 minutes depending upon the thickness of oxide scale.
4.) Use pressurised water Jet Spray or wipe the weld seam lightly with plastic scrubber & rinse the surface thoroughly with water.
5.) Apply STAR Passivation (STAR Pass 1) on the surface area and leave it for about 15 minutes. This will prevent from further contamination and corrosion.
6.) Rinse the surface area thoroughly with water and allow it to dry.
