Indokote SIL250 is single component, silicone acrylic resin based high temperature aluminum coating. SIL250 is designed to provide heat resistant up to 250 °C. It can be used as primer, mid coat or finish coat in atmospheric environments. It is suitable for properly prepared carbon steel, galvanised steel, stainless steel and aluminium substrates.
Indokote SIL250 is suitable for insulated and non insulated surfaces and is recommended as finish coat for insulated surfaces, in systems with suitable primers. It can be dirrectly applied outside storage tanks, furnace, pipe stack, exhaust stacks, ducting radiator, boiler fronts, Chimney as well as structural steel & other surfaces operating at elevated temperatures. Strongly recommended in combination with an inorganic zinc silicate primer to provide long term corrosion protection.

All surfaces to be coated should be clean, absolutely dry and oil or moisture free before painting application. Oil and grease should be removed by solvent cleaning.
Primed Surface : Indokote SIL250 is suitable for application to steelwork freshly coated with zinc silicate shop primers. If the zinc shop primer shows extensive or widely scattered breakdown, or excessive zinc corrosion products, overall sweep blasting will be necessary. Ensure that the zinc primer is fully cured prior to the application of SIL 250.
Steel : Abrasive blast clean to a minimum of Sa2½ (ISO 8501-1:2007). Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner. A surface profile of 30-40 microns is recommended.
Repair & Maintenance : Indokote SIL250 can be applied directly over aged HR Aluminium coating following thorough fresh water washing and degreasing provided the coating to be overcoated is in an intact and tightly adherent condition. Loose or flaking coatings should be removed back to a firm edge and SIL250 or an appropriate primer should be used to repair the area before application of the full coat.
