Multi-Substrate Vacuum Spray Line Solution for Diverse Materials

Multi-Substrate Vacuum Spray Line Solution for Diverse Materials

This solution addresses the challenge of coating diverse substrates: Plastics (ABS, PC, PP, TPE), Glass, Ceramics, and Metals (Al, Zn, SS). The choice of substrate dictates the primer chemistry, surface treatment (plasma/flame), PVD target material, and topcoat requirements. For instance, porous substrates need sealers, while flexible TPE requires specialized soft-touch primers to prevent cracking. Our solution includes customizable jigs and fixtures for each material type.

5 Critical Considerations for Your Solution:
1. Surface Energy: Treat low-energy plastics (PP, PE) with plasma or flame.
2. Thermal Stability: Ensure substrates withstand IR/UV curing temperatures.
3. Outgassing Potential: Proper bake-out is key for plastics in vacuum.
4. Primer Adhesion: Select primer specifically formulated for substrate chemistry.
5. Mechanical Stress: Flexible parts need elastomeric topcoats to prevent crazing.
