ALTIC HRTI 1800°C Water Based Heat Resistant Coating

This water-based coating system consists of a powder and a liquid binder, which are mixed at the time of application. The binder is diluted in water in a 1:6 ratio, and then thoroughly combined with the powder to create a uniform, brushable coating. Once applied and properly cured, the film forms a matte, biscuit-brown textured layer that resists heat, corrosion, and physical wear.

The ALTIC HRTI 1800 Water Base formulation is completely solvent-free, non-flammable, and environmentally safe, providing superior thermal reflectivity and durability without toxic emissions.

Application Procedure

1. Surface Preparation:
   Clean the furnace or oven interior thoroughly using sandpaper to remove dust, carbon, rust, and contaminants. Ensure the surface is completely dry before application.

2. Mixing Process:

   • Mix 100 ml of binder with 600 ml of water (1:6 ratio).

   • Stir well until uniform.

   • Add 1 kg of ALTIC HRTI 1800 powder to the mixture.

   • Blend thoroughly to obtain a homogeneous, lump-free paste.

   • Prepare only the required quantity for each coat to prevent premature hardening.

3. Application:

   • Apply the first coat evenly using a brush.

   • Allow to air dry for 4 hours.

   • Apply a second coat after the first has dried.

   • For adequate film build-up (200 microns), apply an additional coat if coverage exceeds 12 sq. ft/kg.

4. Curing:

   • After application, let the coated surface air dry for 4 hours.

   • During the first furnace firing, increase the temperature gradually at 50°C per hour up to the desired operating temperature.

   • This controlled heating ensures full curing and optimal adhesion of the coating film.
