3 Core Challenges Your Business Faces with Metal Coatings
🔥 High Costs
Traditional coatings (e.g., PTFE, powder) require multi-layer applications, driving up labor and material costs by 40-60%. Liquid silicone reduces this with single-step curing.
⚡ Poor Durability
Conventional coatings crack under thermal cycling. Liquid silicone maintains elasticity from -60°C to 250°C, per Grand View Research.
🛠️ Limited Customization
Rigid coating processes can’t handle complex geometries. Our OEM/ODM liquid silicone molding adapts to any metal substrate with ±0.01mm precision.
