Solvent-Free PU Synthetic Leather Coating Solution
Build a reactive solvent-free PU coating workflow from component preparation through web coating, cure and finishing.
Build the Process Around Your Product
Build a reactive solvent-free PU coating workflow from component preparation through web coating, cure and finishing.
Product and material first
Start with the finished-product drawing, material system and acceptance requirements. The process route and equipment configuration are assessed together.
Capacity across the whole process
Define output with preparation, forming/reaction, curing, handling and inspection included. The slowest stage and product changes determine practical line capacity.
Haifeng metering/mixing/coating equipment interfaces with agreed web handling, curing, lamination and finishing. The existing solvent-free leather project is retained as a project-specific reference.
From Preparation to Qualified Product
A planning sequence for the specified route. Final settings and acceptance conditions are established through material and part review.
Define the leather construction
Confirm substrate, layers, texture, width and final property requirements.
Prepare reactive components
Condition components and additives within the specified viscosity and reaction window.
Meter and mix
Control component ratios and synchronize shot or continuous delivery with the coating demand.
Information Needed to Configure the Line
Provide these inputs so the equipment range, interfaces and validation plan can be defined.
| Design input | Information required |
|---|---|
| Leather construction | Substrate, layer stack, coating weight and working width |
| Reactive system | Component count, ratios, viscosity and reaction time |
| Web output | Speed, roll changeovers and cure residence |
| Quality targets | Adhesion, appearance, physical properties and test methods |
Core Equipment and Integrated Interfaces
Haifeng metering/mixing/coating equipment interfaces with agreed web handling, curing, lamination and finishing. The existing solvent-free leather project is retained as a project-specific reference.
Coordinate the Equipment With the Process
Evaluate repeatability, handling and acceptance across the full workflow.
Material-specific configuration
Component circuits, thermal control, mixing and receiving equipment are matched to the approved chemistry and processing window.
Defined interfaces
Haifeng metering/mixing/coating equipment interfaces with agreed web handling, curing, lamination and finishing. The existing solvent-free leather project is retained as a project-specific reference.
Documented acceptance
The proposal defines trials, process records, inspection responsibilities and product-specific acceptance conditions.
Related Project Records and Industry References
Review the evidence type on each record. Haifeng project figures describe their own configuration; public industry references identify third-party sources and are not Haifeng deliveries.
