BENZIPOX Hi-Heat Primer

Two Pack Silicone Heat Resisting Primer

BENZIPOX HI-HEAT PRIMER is a two pack heat curing modified silicone heat resisting which containing zinc dust that provides perfect corrosion protection to blasted steel surface (Sa 2.5) in highly corrosive environment. It can withstand surface dry heat temperature up to 600°C under atmospheric exposure conditions provided over-coated with suitable topcoat. It is recommended for use on furnace, chimney, exhaust, boiler, oven, machinery and engine room.

Painting System:

Surface Preparation

Ferrous Metal Surface
The service life span and performance of BENZIPOX Hi-Heat Primer is directly related to the degree of surface preparation. Please observe the following:-

  • Remove all wax, oil and grease by solvent cleaning (SSPC-SP1);
  • Remove weld spatter and round off all rough weld seams and sharp edges to a smooth surface;
  • Surface shall be abrasively blasted to a minimum standard of Sa 2.5 (ISO 8501-1:1988) or SSPC-SP10;
  • An average surface profile of 50 microns is acceptable but this average should not exceed 75 microns;
  • Surface to be coated shall be clean, dry and free from any contamination;
  • Apply BENZIPOX Hi-Heat Primer immediately after blasting / cleaning as to prevent oxidation and recontamination of the surface. If oxidation or recontamination occurred, reblast to the required standard;
  • Avoid condensation of moisture onto surface prior to coating application, relative humidity should not exceed 85% and surface temperature should more than 3°C above Dew Point.

Safety, Health & Environment

FLAMMABLE. During painting, make sure no source of ignition at surrounding and no smoking. When not in use, store paint in cool and shaded place and do not directly expose to sunlight. Allow proper ventilation and wear mask during painting. Do not breathe vapour or spray. Keep doors and windows open during application and drying. It is advisable to wear eye protector while applying. In case of contact with eyes, rinse immediately with plenty of water and seek medical treatment. To remove splashes of paint from skin, use suitable cleanser or soap and water. Do not dispose paint into drains or watercourses. Refer to MCI Paint Technical Data Sheet (TDS) for further details.
