What ingredients can be sprayed by electrostatic powder spraying?
Electrostatic powder spraying can be used to apply a variety of ingredients, primarily powder coatings. These coatings are made up of several key components that contribute to their overall performance and application properties. The main ingredients include:
1. **Resins**:
– **Epoxy Resins**: Provide strong adhesion, chemical resistance, and mechanical properties.
– **Polyester Resins**: Offer excellent weather resistance, flexibility, and UV stability.
– **Hybrid Resins (Epoxy-Polyester)**: Blend the properties of epoxy and polyester resins for a balance of performance.
– **Acrylic Resins**: Known for their durability, color retention, and weatherability.
2. **Curing Agents**:
– These are chemicals that react with the resins during the curing process to form a hard, durable coating. Common curing agents include:
– **Polyamines** for epoxy systems.
– **Triglycidyl isocyanurate (TGIC)** for polyester systems.
– **Blocked isocyanates** for hybrid and polyurethane systems.
3. **Pigments**:
– Provide color and opacity to the coating. Pigments can be organic (for vibrant colors) or inorganic (for durability and heat resistance).
4. **Fillers**:
– Used to enhance specific properties like mechanical strength, thermal stability, and cost reduction. Common fillers include:
– **Calcium carbonate**
– **Silica**
– **Barium sulfate**
5. **Additives**:
– Improve various properties like flow, leveling, surface finish, and performance. Typical additives include:
– **Flow modifiers** (e.g., acrylic or silicone-based additives)
– **Degassing agents** to prevent pinholes.
– **Antimicrobial agents** for hygiene-sensitive applications.
6. **Plasticizers**:
– Occasionally added to improve flexibility and reduce brittleness, especially in thermoplastic powders.
These ingredients are finely ground and mixed to form a homogenous powder, which is then applied using electrostatic spraying equipment. The electrostatic charge helps the powder adhere uniformly to the substrate, which is then cured by heat to form a hard, durable coating.
