6.2 Aesthetic Value in Polyamide Based Polyurethane Coatings (Room 240-242)

10 Apr 18
9:30 AM - 10:00 AM

Tracks: Session 6: Polyurethanes I

We developed a novel type of polyurethane technology based on polyamide soft segments. Recently we showed that these materials can be used to make high performance coatings and commercialized the first polyurethane dispersions for metal and wood applications. In this paper we demonstrate how polyamide-based urethane coatings not only provide high quality finishes, they also conform to specific aesthetic expectations: high clarity matte finishes (gloss <10) without added flattening agents, dispersions matching solvent borne aesthetic qualities (gloss and DOI), and coatings with other surface effects can be designed. Application specific properties and the role of the polyamide soft segment in obtaining these unique properties will be discussed for wood, metal and plastic coatings.
