Production Process

The Production Process Production Stage covers the application of the polymer resin to the substrate material. The following process options are available:

  • Wet and dry process is the default process and should be used unless another process is applicable. In this process, the substrate is coated with a resin, which is then coagulated in baths of dimethylformamide and water. At the same time, a layer of resin is applied to one side of the material using a release paper to create an additional layer for further function and aesthetic.
  • Wet process only should be selected when the substrate is only coated with a resin, which is then coagulated in baths of dimethylformamide and water.
  • Synthetic leather production, dry process only should be selected when the substrate is only coated with a layer of resin using a release paper, essentially laminating a polymer layer to the surface of the substrate.
  • Dry process, Haptex non-solvent 2K PU synthetic leather (solvent based top coat) {BASF} should be selected when using the PU type Haptex non-solvent 2K PU (solvent based top coat) from BASF. 
  • Dry process, Haptex non-solvent 2K PU synthetic leather (water based top coat) {BASF} should be selected when using the PU type Haptex non-solvent 2K PU (water based top coat) from BASF.
  • Wet and dry process, solvent-based PU synthetic leather {BASF} should be selected when using generic solvent based PU synthetic leather.
  • Wet and dry process, water-based PU synthetic leather {BASF} should be selected when using generic water based PU synthetic leather.
