JLTL BPO 280°C High Temperature Conductive Body Filler is a BPO-cured polyester repair putty developed for industrial powder coating, electrostatic powder spraying and high-temperature baking processes.
Unlike conventional automotive body filler intended primarily for normal automotive paint systems, this product is designed for industrial metal repair where the repaired surface may subsequently enter a high-temperature powder-coating oven.
It combines several requirements that are important for powder-coating preparation:
Typical defects that can be repaired include casting porosity, pinholes, small cavities, welding marks, scratches, dents and surface irregularities before powder coating.
BPO high-temperature conductive body filler is a two-component polyester repair material using a BPO curing system.
The product consists of:
Polyester Body Filler + Red BPO Hardener
Recommended mixing ratio:
Body Filler : Hardener = 100 : 2 by weight
After application, the material is allowed to cure at room temperature, followed by sanding and surface preparation before the workpiece enters the powder-coating process.
The conductive formulation is intended to make the repaired area more compatible with electrostatic powder-coating processes than a conventional non-conductive repair filler.
A typical industrial powder-coating workflow can involve:
Metal Workpiece
↓
Degreasing / Surface Treatment
↓
Defect Repair
↓
Sanding
↓
Electrostatic Powder Spraying
↓
High-Temperature Baking
The repair material therefore needs to remain sufficiently stable during the subsequent baking stage.
A conventional filler that is not designed for this process may experience problems such as:
JLTL BPO High Temperature Conductive Body Filler is developed specifically for applications requiring approximately 280°C short-term heat resistance during powder-coating baking.
280°C refers to short-term resistance during the powder-coating baking process.
It should not be interpreted as continuous long-term service at 280°C.
Applications involving continuous exposure above the rated temperature should be evaluated separately.
Electrostatic powder coating relies on electrostatic attraction between the charged powder and the workpiece.
When a repair filler is applied to a conductive metal surface, differences in electrical behavior between the repair area and surrounding substrate may affect powder deposition.
JLTL BPO High Temperature Conductive Body Filler uses a conductive formulation intended for powder-coating applications.
It can help make the repaired surface more suitable for subsequent electrostatic powder application and reduce concerns associated with a highly insulating repair area.
Actual powder deposition remains dependent on the complete coating process, including substrate preparation, grounding, powder system, spray parameters and oven conditions.
One of the key advantages of this product is its application across multiple industrial metal substrates.
Recommended substrate directions include:
This makes the product suitable for factories producing different types of metal components without requiring a separate conventional filler for every substrate.
Aluminum castings For casting porosity, pinholes and small surface defects.
Steel structures For welding marks, dents and surface irregularities.
Stainless steel components For equipment housings, cabinets and fabricated components after appropriate surface preparation.
Aluminum alloy parts For industrial components requiring repair before powder coating.
Aluminum castings frequently contain small surface defects that become more visible after powder coating.
Typical repair defects include:
The BPO high-temperature conductive filler can be used to fill and level these defects before sanding and subsequent powder coating.
Aluminum Casting
→ Degrease
→ Mechanically prepare surface
→ Apply BPO high-temperature conductive filler
→ Cure
→ Sand and level
→ Powder coating
→ High-temperature baking
For aluminum and other difficult substrates, thorough degreasing and mechanical surface preparation remain important for achieving reliable adhesion.
The product is suitable for surface preparation on industrial metal components such as:
It can help repair imperfections created during:
After curing and sanding, the repaired surface can proceed to the subsequent powder-coating process.
Industrial and commercial metal products often require a smooth surface before powder coating.
Potential applications include:
Welded joints, small dents and surface imperfections can be repaired before the final powder coating process.
This is especially useful when the final powder coating is intended to provide a uniform decorative and protective surface.
The product can also be considered for compatible metal components that will subsequently undergo powder coating, including:
The key application principle is that the repaired component must be suitable for the complete powder-coating process and the substrate must be properly prepared.
JLTL BPO 280°C High Temperature Conductive Body Filler can be used for filling and leveling defects such as:
| Defect | Application |
|---|---|
| Casting Porosity | Casting repair |
| Pinholes | Metal surface repair |
| Small Cavities | Surface filling |
| Weld Marks / Weld Areas | Fabricated metal |
| Scratches | Surface leveling |
| Small Dents / Dings | Panel repair |
| Casting Defects | Aluminum / metal castings |
| Surface Irregularities | Pre-powder-coating preparation |
High-temperature resistance alone is not sufficient for an industrial repair filler.
The material also needs to be practical during factory production.
JLTL BPO High Temperature Conductive Body Filler is designed to provide:
Suitable for filling small cavities, pinholes, scratches and other surface defects.
Designed for practical spreading and leveling during manual repair.
Allows the operator to build up and shape the repaired area before final sanding.
The cured filler can be sanded to obtain a smooth transition before powder coating.
For better process stability, multiple thin applications are recommended instead of applying one excessively thick layer.
Remove oil, grease, dirt and other contamination from the metal surface.
Remove active rust, loose coating and unstable surface material.
Sand the substrate adequately to create a suitable surface for filler adhesion.
Mix the body filler with the red BPO hardener at:
100 : 2 by weight
Mix thoroughly and evenly.
Apply to the prepared defect area.
For deeper defects, use multiple thin applications rather than one excessively thick layer.
Allow the filler to cure under appropriate ambient conditions.
Sand the repaired area until the required surface profile and smoothness are achieved.
Proceed with the compatible powder-coating system after confirming that the repaired surface is properly prepared.
The coated workpiece can enter the powder-coating baking process within the product's intended temperature and exposure conditions.
Even a high-temperature filler cannot compensate for poor substrate preparation.
Before application, the surface should be:
Clean + Dry + Degreased + Stable + Properly Roughened
Particular attention should be given to:
Remove oil and contamination and mechanically prepare the surface adequately.
Remove grease and contaminants and provide appropriate mechanical keying.
Remove rust, scale and loose material before application.
Ensure the phosphated surface is clean, dry and suitable for the selected repair process.

Different powder-coating production lines may use different curing conditions.
A lower-temperature industrial filler may be adequate when the subsequent process operates within its rated temperature range.
The BPO 280°C high-temperature conductive filler is intended for applications where customers require a higher temperature margin during the powder-coating baking process.
Standard / Lower-Temperature Powder Coating
→ Select a filler whose temperature rating matches the actual process.
Higher-Temperature Powder-Coating Process
→ Consider a product specifically designed for the required temperature range.
Electrostatic Powder Coating
→ A conductive filler is more appropriate than a conventional insulating repair filler when the repaired area needs to participate in the powder-coating process.
This product is not intended for every repair application.
If the repair only requires normal automotive painting or baking temperatures up to approximately 160°C, a conventional body filler may be more economical.
If electrostatic powder coating is not involved and conductivity provides no process benefit, a conductive filler may not be necessary.
The stated 280°C rating refers to short-term exposure during powder-coating baking, not continuous long-term operation at 280°C or higher.
Even a high-temperature filler should be applied in reasonable thicknesses. Deep defects should generally be repaired through multiple layers.
Oil, moisture, loose rust and unstable coatings can compromise adhesion.
