7862746, Jan 4, 2011

Filed:

Feb 13, 2006

Appl. No.:

11/352873

Inventors:

Sarah R. Kaspers - Scarsdale NY, US
Christian Guckel - Bad Saeckingen, DE
Daniel Rogez - Mulhouse, FR
Christian M. Schaller - Basel, CH

Assignee:

BASF SE. - Ludwigschafen

International Classification:

B23B 15/08

US Classification:

252397, 524 13, 252401

Abstract:

The invention relates to a method of stabilizing natural composites against damage by heat and light by treating the wood derived fillers with a water based solution of a sterically hindered amine, drying the treated wood derived filler and then combining with plastic via compounding methods such as extrusion.

Appl. No.:

11/446843

Inventors:

Ashutosh Sharma - Wappingers Falls NY, US
Peter Solera - Suffern NY, US
Sarah Kaspers - Scarsdale NY, US

International Classification:

C08K 5/34
C08L 37/00

US Classification:

524098000, 524104000, 524549000

Abstract:

Polyolefin substrates, for example polypropylene, polyethylene or thermoplastic olefin molded parts, are made scratch resistant and heat and light stable by the incorporation therein of an additive combination of b) a carboxylic acid reagent functionalized olefin polymer or copolymer, c) a primary or secondary fatty acid amide and d) a combination of a low molecular weight and a high molecular weight hindered amine light stabilizer. The present polyolefins exhibit good weatherability, scratch resistance, good processability, good mechanical strength, good gloss retention and are non-sticky. The carboxylic acid reagent functionalized olefin polymer is for example maleic anhydride grafted polypropylene or polyethylene, or is a reaction product of maleic anhydride and an alpha-olefin, or is a tallow alcohol ester of said maleic anhydride products. The fatty acid amide is for example oleyl palmitamide or stearyl erucamide.

US Classification:

524115000, 524210000, 524236000

Abstract:

Polymer substrates, for example ABS, PBT, PVC, PET, nylon 6, nylon 6′6, ABS/PBT, PC/ABS or ionomers, are made scratch resistant by the incorporation therein of an additive combination of b) a carboxylic acid reagent functionalized olefin polymer or copolymer and c) a primary or secondary fatty acid amide. The present polymers exhibit good weatherability, scratch resistance, good processability, good mechanical strength, good gloss retention and are non-sticky.

US Classification:

524230000, 524529000

Abstract:

Coatings compositions, for example oil or water based coatings with alkyd, acrylic, acrylic alkyd, polyester, phenolic, melamine, epoxy or polyurethane resins, are made scratch resistant by the incorporation therein of an additive combination of b) a carboxylic acid reagent functionalized olefin polymer or copolymer and c) a primary or secondary fatty acid amide. The present coatings exhibit good weatherability, scratch resistance, good gloss retention and are non-sticky. The carboxylic acid reagent functionalized olefin polymer is for example maleic anhydride grafted polypropylene or polyethylene, or is a reaction product of maleic anhydride and an alpha-olefin, or is a tallow alcohol ester of said maleic anhydride products. The fatty acid amide is for example oleyl palmitamide or stearyl erucamide.
