Assignee:

BASF Corporation - Southfield MI

International Classification:

B05C 1300

US Classification:

118500, 118503

Appl. No.:

10/420046

Inventors:

William H. Merritt - Ferndale MI, US
Craig S. Schang - Brighton MI, US

Assignee:

BASF Corporation - Southfield MI

International Classification:

B32B025/08
B05D003/02
C08L023/28
C08L053/00
C08L033/14

US Classification:

525 91, 4273935, 428483, 524505, 525 90, 525 92 C, 525 92 F, 525 92 H, 525 92 K

Abstract:

The composition is an adhesion promoter that includes a chlorinated polyolefin and an olefin-based block copolymer that has an olefin block that is substantially saturated and at least one (poly)ester or (poly)ether block. The olefin-based block copolymer can be prepared by reacting an hydroxyl-functional, saturated or substantially saturated olefin polymer with a chain-extension reagent that is reactive with hydroxyl groups and will polymerize in a head-to-tail arrangement of monomer units. The composition provides excellent adhesion to olefinic substrates like TPO. A method of making the adhesion promoter composition includes forming the olefin-based block copolymer, providing the copolymer at temperatures between 85 C. and 50 C. and adding, with agitation, chlorinated polyolefin to the copolymer at these temperatures.

Assignee:

BASF Coatings GmbH - Muenster

International Classification:

C08L 53/00

US Classification:

525 91

Abstract:

The present invention is an adhesion promoter, a coating composition containing the adhesion promoter and a method for preparing the adhesion promoter and coating. The adhesion promoter of the present invention is an olefin based polymer prepared by reacting a hydroxy functional olefin polymer with a compound reactive with hydroxy functionality to provide functionality on the olefin polymer that is inert to reaction with a principal resin or crosslinking resin in a coating composition.

International Classification:

C08L 33/14

US Classification:

525208, 525207

Abstract:

A coating composition comprises a first copolymer and a second copolymer. The first copolymer has at least one linear polymer strand having a weight average molecular weight of at least 1,500 Daltons and functionality X with an equivalent weight of no more than 500. The second copolymer has at least one linear polymer strand having a weight average molecular weight of at least 1,500 Daltons and functionality X′ with an equivalent weight of no more than 1,500. The coating composition is free of gloss flattening agents, yet still produces a cured film having a low gloss of less than 70 gloss units at an angle of incidence of 60, as measured according to ASTM D 2457.

International Classification:

C08L 65/00
C08F 110/00

US Classification:

525416, 526348

Abstract:

A method of making an organic solution of a chlorinated polyolefin that produces a storage-stable solution, a chlorinated polyolefin resin is dissolved in a hydrocarbon solvent that is predominantly aliphatic hydrocarbon, aromatic hydrocarbons other than toluene and xylene, or mixtures of these, held at a temperature from 118 to 125 C., for an adequate time for complete dissolution, then cooled and a cosolvent is added at a temperature below the boiling point of the cosolvent but at a temperature at which the chlorinated polyolefin solution is still clear or has little haziness. The solution can be used to prepare coatings, primers, inks, and adhesives, particularly for plastic substrates such as thermoplastic polyolefin.
