Scuff resistant and chip resistant architectural compositions

Solutions to the problems of scuffing and chipping of the paint films in high traffic areas and in tight spaces, such as dressing rooms in department stores, where multiple scrapings of the wall paints are created by consumers, clothes hangers, shoes, etc., and hallways and conference rooms in office and other commercial buildings are disclosed. Wax seeded latex polymers admixed with an added wax in architectural compositions and optionally with polyurethane resin are utilized to create paint films that are resistant to scuffing and chipping.

20230294346 · 2023-09-21 · ·

A maleimide-based copolymer having superior dispersibility during melt extrusion and kneading. A maleimide-based copolymer having an average particle diameter of 75 μm or larger and a cumulative oversize at 1000 μm of lower than 5 mass %.

Synthetically modified thermoplastic polymer composites having cellulose nanomaterials

A method of manufacturing a polymer coated cellulose nanocrystal composite material begins with an aqueous cellulose nanocrystal (CNC) suspension mixture. The aqueous CNC suspension mixture is dried to remove the liquid solvent from the aqueous CNC suspension mixture to form a dry CNC powder. Diethylenetriamine (DETA) is combined with melted Maleated-anhydride Polypropylene (MAPP) to form a DETA-functionalized MAPP (MA) mixture. The MA mixture is cooled and pelletized to form MA pellets. The MA pellets, the dry CNC powder, and a neat polypropylene (PP) are combined to form a CNC-PP mixture. The CNC-PP mixture is compounded by melting, subsequently cooled and pelletized to form CNC-PP pellets.
