UV Cure Platforms from Bayer

Waterborne UV coating systems -

Bayer's toolbox of Bayhydrol® UV curing polyurethane dispersions

The characteristic properties of UV cure coating systems within waterborne coating technology are:

• Chemical crosslinking 1C — systems
• Have no pot life
• Yield high level of chemical and physical resistance
• Have a good recyclability
• Use no dangerous crosslinkers

The characteristic properties of waterborne coating systems within UV cure coating systems are:

• Easy to matt
• Superior in adhesion
• Simple and easy application by spraying

Waterborne UV cure coating systems can be used in a variety of applications:

• Decorative film and sheeting
• Doors
• Flooring, including parquet flooring and PVC flooring (industrial)
• Furniture (bedroom, chairs, kitchen, living room, tables)
• Leather
• Overprint varnishes
• Plastics
• Profile

UV curing polyurethane dispersions offer the following benefits to coating formulators:

• High-grade polyurethane chemistry with all possible variations
• No mixtures with
  • Polyester acrylate (PAC), PU-PAC dispersions
  • Reactive thinners
• Molecular weights
  • Emulsions: > 10,000 g/mol
  • Dispersions: > 200,000 g/mol

Technologies for formulating waterborne UV cure coating systems

• Polyester acrylate emulsions
  • Emulsions of polyester acrylate using emulsifiers or protective colloids
• Unsaturated polyester resin emulsions
  • Self-emulsifying allyl polyester resin
• Unsaturated polyurethane resin emulsions
  • Polyurethane emulsions, medium molecular weight
• mixtures
  • emulsifying of reactive thinners in polyester acrylate (PAC) or PU-PAC dispersions
  • mixtures of UV curing polyurethane dispersions with PAC dispersions
• polyurethane dispersions (PUD)
  • polyurethane dispersions, high molecular weight
  • polyurethane dispersions, medium molecular weight
