Performance

  • Wetting and levelling

PRO21536 is a wetting additive that yields superb even films, free from surface defects

- high gloss
- save on additives

 

  • Hydrophobicity

A cured film containing PRO21536 will demonstrate
- very high hydrophobicity
- increased water resistance
- adhesion in outdoor applications, humid environments or where pasteurization or sterilization are required
- enhanced stain and chemical resistance

 

  • Slip and anti-blocking

The use of PRO21536 in UV coating formulations
- prevents blocking in re-reeled applications (e.g. coil coatings or film coatings)
- provides protection against scuffing, marring and scratching
