In the paint, the polycaprolactone polyol can be used as reactive diluent and modifier in polyurethane, acrylic, polyester, epoxy and vinyl coatings. When polycaprolactone polyol is used as reactive diluent, can be used in baking-type melamine and room temperature curing isocyanate cross-linking agent coating. When as a solvent modifier in paint, in addition to reducing VOC, it also can get the necessary balance of hardness and flexibility and does not affect the film properties.
Benefits
Highly functional liquid polyols produce flexible
Low-viscosity polyols and pre-polymers reduce/eliminate solvent and VOCs
Very good hydrolysis resistance compared with other polyesters
Polyester gives excellent solvent, chemical and UV resistance
Low Tg (-60°C) gives good low-temperature flex properties
provides good bonding to substrates
High-clarity, light stable coatings
Consistent, controlled reactivity
Stable pre-polymers
