LEVELLING AGENT HL505

Levelling Agent HL505 is a polyacrylate-based flow additive designed to improve surface smoothness and film uniformity in powder coating systems.
Levelling Agent HL505 helps reduce common coating defects such as craters, fish-eyes, orange peel, and poor wetting by lowering surface tension during curing.
Levelling Agent HL505's use in epoxy, polyester, hybrid, polyurethane, and other powder coatings supports better gloss, improved substrate wetting, and a more professional final coating appearance.

Levelling Agent HL505 is a polyacrylate with silica carrier.
Levelling Agent HL505 acts as a leveling agent.

Levelling Agent HL505 eliminates the fish-eye & crater and reduces surface tension of film.
Levelling Agent HL505 improves wettability to base substrate and reduces the cost.

Levelling Agent HL505 is used in epoxy, hybrid, pure polyester, polyester, polyurethane and other thermosetting, thermoplastic powder coatings.
Levelling Agent HL505 recommended dosage is 2-3% of the total weight.

Levelling Agent HL505 is a flow and leveling additive used in thermosetting powder coating formulations.
Levelling Agent HL505 helps reduce surface tension during melting and curing, allowing the coating film to spread more evenly and form a smoother surface.

Levelling Agent HL505 is used to minimize common surface defects such as orange peel, craters, pinholes, fisheyes, poor wetting, and uneven film formation.
Levelling Agent HL505 is suitable for powder coating systems where better flow, improved gloss, smoother appearance, and more uniform surface quality are required.

Uses of Levelling Agent HL505:
Levelling Agent HL505 is used as a flow and leveling additive in thermosetting powder coating formulations.
Levelling Agent HL505 helps the melted coating spread evenly during curing, reduces surface tension differences, and supports the formation of a smoother, more uniform coating film.

Levelling Agent HL505 is mainly used to reduce orange peel, craters, pinholes, fisheyes, poor wetting, and uneven surface appearance.
Levelling Agent HL505 is suitable for smooth powder coatings based on epoxy, polyester, hybrid epoxy-polyester, polyurethane, and acrylic systems, and it is typically added during the premix stage before extrusion.
General powder-coating leveling additives are commonly used at low dosage levels to improve gloss, film fullness, substrate wetting, flow, and final surface quality.

Stability and Reactivity of Levelling Agent HL505:

Chemical stability:
Levelling Agent HL505 is stable under normal recommended handling and storage conditions.

Reactivity:
No dangerous reaction is expected when the product is used and stored properly.

Conditions to avoid:
Excessive heat, open flames, sparks, ignition sources, dust formation, moisture exposure, and poor ventilation should be avoided.

Incompatible materials:
Strong oxidizing agents, strong acids, strong bases, and highly reactive chemicals should be avoided.

Hazardous decomposition products:
Thermal decomposition or fire may produce carbon oxides, irritating smoke, and organic decomposition fumes.

Dust hazard:
Fine powder may form airborne dust during weighing, mixing, transfer, or powder-coating production.

Handling and Storage of Levelling Agent HL505:

Handling:
Levelling Agent HL505 should be handled using good industrial hygiene and safety practices.

Safe handling:
Avoid breathing dust and avoid direct contact with skin, eyes, and clothing.

Ventilation:
Use adequate general ventilation or local exhaust ventilation when dust may be generated.

Processing note:
Add the leveling agent during the premix stage and mix it well with other raw materials before extrusion in smooth powder-coating formulations.

Storage:
Store in a cool, dry, and well-ventilated area.

Storage protection:
Keep the container tightly closed and protect it from moisture, heat, direct sunlight, ignition sources, and incompatible materials.

First Aid Measures of Levelling Agent HL505:

Inhalation:
Move the affected person to fresh air and keep them comfortable for breathing.

Skin contact:
Wash the affected area with soap and plenty of water.

Eye contact:
Rinse cautiously with water for several minutes and remove contact lenses if present and easy to do.

Ingestion:
Rinse mouth with water.

Do not induce vomiting unless instructed by medical personnel.

Medical attention:
Seek medical advice if irritation, coughing, breathing discomfort, or other symptoms continue.

Firefighting Measures of Levelling Agent HL505:

Suitable extinguishing media:
Use water spray, foam, dry chemical powder, or carbon dioxide.

Specific hazards:
Levelling Agent HL505 is an organic powder-coating additive, and burning may produce irritating smoke and carbon oxides.

Dust hazard:
Avoid creating dust clouds because fine organic powders may present a combustible dust risk in air.

Protective equipment:
Firefighters should wear full protective clothing and self-contained breathing apparatus.

Firefighting precautions:
Cool exposed containers with water spray and prevent contaminated firefighting water from entering drains or waterways.

Accidental Release Measures of Levelling Agent HL505:

Personal precautions:
Avoid dust formation and avoid breathing dust.

Protective equipment:
Wear suitable gloves, eye protection, protective clothing, and a dust mask if airborne dust may occur.

Environmental precautions:
Prevent large quantities from entering drains, soil, surface water, or groundwater.

Cleaning method:
Sweep or vacuum the spilled powder carefully using dust-control methods.

Disposal:
Place collected material into a suitable closed container and dispose of it according to local, regional, and national regulations.

Exposure Controls / Personal Protection of Levelling Agent HL505:

Engineering controls:
Use adequate ventilation, especially during premixing, weighing, transfer, extrusion preparation, or other dust-generating operations.

Respiratory protection:
Use a suitable dust mask or respirator if ventilation is insufficient.

Eye protection:
Wear safety glasses or chemical safety goggles.

Skin protection:
Wear protective gloves and suitable work clothing.

Hygiene measures:
Wash hands after handling and before eating, drinking, smoking, or leaving the work area.
