Application Procedure HJ-1138
1. Flush all equipment with recommended cleaner before use.
2. Stir the product thoroughly with a power mixer.
3. For air spray, thin with no more than 5% of recommended
thinner for workability.
4. Apply a wet coat by parallel passes. Overlap each pass 50%
to avoid bare areas, pinholes or holidays.
5. Preceding coat: can be used directly on blast – cleaned steel .
for maximum protection a primer coat of one of the following
paints is recommended (40 micron /1.6 mil dry film thickness:
HJ-732 or HJ-7311
This will lower the heat resistance to approx 400° C / 750° F.
6. Film thickness: it is recommended to avoid to high thickness
of the paint as this will give a risk of blistering at later heating.
Thinner HJ-71 must be added at application to secure the low
dry film thickness.
7. Recoating: May be recoated when thorough dry (24 hrs at
° C ) or after being heated for one hour to approximately
0° C/392° F.
Before recoating after exposure in contaminated environment
clean surface thoroughly by high pressure fresh water hosing
and allow to dry.
6. Double coat all welds, rough spots, sharp edges, rivets,
bolts, etc. to ensure proper thickness.
8. Random pinholes, holidays and small damaged or bare areas
can be touched up by brush when the film is dry to touch.
Larger areas should be resprayed.
9. In confined areas ventilate with clean air during application
and drying until all solvents are removed.
10. Clean all equipment with recommended cleaner
immediately after use.
Heat curing and baking
Baking causes all the hydroxyl group still present in silicon
resins to condense. When this has been achieved the resultant
paint film will have maximum resistance to heat, corrosion and
chemicals. To achieve fast & complete curing of the paint film
it should be heated for one hour at 230°C. It is preferable to
raise the temperature gradually. Although lower temperature or
shorter baking times can produce hard paint films, the films
may not be fully cured.
Surface temperature must be at least 3°c above dew point.
Relative humidity during application should be less than 80%.
Do not apply coatings under reverse environmental conditions.
This product is flammable. Keep away from heat
and open flame. Keep container closed. Avoid
prolonged and repeated contact with skin.
Since improper use and handling can be hazardous
to health and cause fire or explosion, safety
precautions included with application instructions
must be observed during all storage, handling, use
and drying periods.
If used in confined areas:
- circulate adequate fresh air continuously during
application and drying.
- Use fresh air masks and explosion proof
- Prohibit all flames, sparks, welding and smoking
- Take precautionary measures against static
Keep away from food products.
Storage and Handling
The products must be stored in accordance with
national regulations.
The products should be kept in a cool and well
ventilated place protected from heat and direct
sunlight. Containers must be kept tightly closed.
