Varese, Italy -- A three-company collaboration has led to the development of a coalescent-free polyurethane wood coating with traditional performance properties, they claim.
In a press release, Sapici, Liberty Chemicals and Galactic said the PU's performance is aligned to traditional coating formulations yet it has a “high environmental compatibility.”
Made from biological/renewable sources, the cooperation between the companies brought “outstanding results even at low concentrations of green-coalescent” said the release.
The new coating comprises Sapici’s coalescent-free PUD resin Bluepur 2937, Galactic’s Galaster series lactic-acid esters to enable the filming effect with water-based products and a Liberty Chemicals solvent derived from 'fermented natural molecules.'
“These products allow for finishing values of 90 gloss” and increased “sustainability due to low raw material consumption” said the companies.
Sapici develops and manufactures waterborne polyurethane dispersions, Liberty Chemicals produce bio molecule solvents while Galactic's specialty is in lactic acid derivatives.
