Application Procedure and Other Details
| Mixing |
: |
The paint is supplied in two separate containers Pack (A) and Pack (B).
Shake well both the containers before use.
Mix the components in proper ratio by uniform Stirring.
Once the components are mixed, it must be used within working pot life period. |
| Mixing Ratio |
: |
1 : 1 by Volume |
| Working Pot Life ( at various temp.) |
: |
2 Hours ( below 25 0C ),1.5 Hours ( upto 40 0C )
1 Hour ( above 40 0C ) |
| Method of Application |
: |
The paint can be applied by any method e.g. brush, Air spray, Airless Spray, Roller, Dipping Flow coating, Curtain coating, Tumbling etc. |
| Film Thickness |
: |
The wet film thickness ( WFT ) should not be less than 50 microns. |
| Thinner |
: |
Use G-Tech Thinner for thinning the paint. Do not thin more than required. |
Passes following standards
(1) IS 13183:1991 for Grade-1
Aluminium Heat resistant paint
(2) BS-476-Part 5-1979
Test for ignitibility (Fire test on building materials)
(3) ANSI/IEEE Standard 383-1974
Test for Class IE Electric Cables, Field Splices and connections for Nuclear Power Generating Stations
(4) BS- 476- Part 7
Test for Surface spread of flame
(5) IS 12777 : 1989
Test for flame spread of product
Surface Preparation
- All surfaces to be coated must be perfectly cleaned. The presence of oil grease, dust, rust, etc. on the surface will not give satisfactory result.
- Oil grease should be removed by either wipe out method or solvent/emulsion degreasing method
- Rust, scales and other deposites on the metal surface should be cleaned by abrasive blast cleaning method or by using wire brushes or abrasion tools.
- DO NOT APPLY ANY TYPE OF PRIMER OR SEALER ON THE SURFACE
- The paint should be applied directly on the surface. It can be recoated any number of times to increase the film thickness.
- The hard dry time (Air dry) of the paint is 24 hours but it can be dried hard within one hour by stoving at 120 0C.
