Twisting resin properties: Pplycaprolactones, a versatile tool ti modify coating formulations

摘要

Polycaprolactones are aliphatic, liquid, solvent-free polyols suitable as reactive diluents in many types of crosslinked coatings. Even though 2K PUR is such a well-established technology there is a constant pressure to improve and fine-tune technical properties such as abrasion resistance, scratch resistance and outdoor durability. Regulations also force formulators tofurther reduce VOCs in high solid (HS) formulations to meet further demands or as another option look at waterborne(WB) solutions. Very low viscosity polycaprolactones can influence both VOC and technical properties to give lower emissions and prolong the life-cycles of coating systems, important criteria for improved sustainability.
