International Classification:

C08F 2/14

US Classification:

526213, 526 89, 526194, 526204, 526217

Abstract:

The present process is directed to preparation of addition polymers in diluents that are subsequently reactive in coatings during cure, instead of in traditional hydrocarbon solvents. The polymers so prepared can be used as the main film-forming polymer in high solids coating compositions, especially those useful for finishing automobiles and truck exteriors.

International Classification:

C08K003/00
C08K003/04

US Classification:

524/589000, 524/495000

Abstract:

The present invention provides for a one-pack primer-sealer composition for molded SMC parts such as automotive body panels that significantly reduces paint defects (such as paint pop and cracking defects) in the sealing and automotive OEM finishing operations. The coating composition includes silane and melamine components. The composition is sufficiently stable to be formulated as a one-pack coating composition.

International Classification:

B05D003/02
B32B009/04

US Classification:

428447000, 427372200

Abstract:

The present invention provides for a primer-surfacer composition for use over sealed SMC parts such as automotive body panels that significantly reduces paint defects (such as paint pop and cracking defects) from appearing in the subsequently applied automotive topcoat finish. The coating composition includes silane and melamine components. The composition is sufficiently stable to be formulated as a one-pack coating composition.

Inventors:

Ayumu Yokoyama - Clarkston MI, US
Basil Gregorovich - Wilmington DE, US
Robert Matheson - West Bloomfield MI, US
Li Lin - Wallingford PA, US

International Classification:

B05D 3/02
B05D 1/36

US Classification:

427372200, 427402000

Abstract:

This invention relates to a method for maximizing the stone chipping resistance and scratch resistance of a multi-layer finish on an automotive substrate. A colored basecoat is applied to the substrate and directly on top of the basecoat is applied a protective clearcoat having a fracture resistance about equal to or above 26 mN and a plastic deformation resistance about equal to or above 30 mN/μm. The resultant coating in addition to being durable to the elements and having excellent appearance produces a finish with an outstanding balance of scratch and stone chip resistance after application.

Inventors:

Delson Jayme Trindade - Rochester Hills MI, US
Robert R. Matheson - West Bloomfield MI, US

International Classification:

B05D 3/02
C08K 3/36

US Classification:

427387, 524450

Abstract:

The present invention is a coating composition containing a mixture of at least one diurea compound and at least one layered silicate mineral. The composition is particularly useful for a basecoat composition in a wet-on-wet basecoat/clearcoat application and is useful as a basecoat in a wet-on-wet-on-wet primer/basecoat/clearcoat application process.
