摘要:
The present invention provides improved adhesion promoters for latex paints. The adhesion promoters are enamines of acetoacetate esters, or substituted acetoacetate esters. The invention also provides two new compounds which are useful as adhesion promoters: 2-butyl-2-ethyl-1,3-propanediol bis(3-amino-2-butenoate) and trimethyl propane tris(3-amino-2-butenoate), and which are stable to hydrolysis on prolonged storage.
摘要:
A hypoallergenic adhesive article employing a switchable pressure sensitive adhesive (PSA) composition comprising one or more amphiphilic polyesters in physical mixture with a humectant. When contacted with a liquid of low-ion content, the adhesive undergoes a reduction in peel strength, which allows for easy removal, but remains strongly adhered when contacted with ionic liquids, such as blood, sweat, and other bodily fluids. The adhesive composition can be employed in a variety of medical articles or in other similar applications.

摘要:
This invention provides esters of acetoacetic acid useful as adhesion promoters for waterborne coatings compositions applied to corroded or rusty metal substrates. The esters of acetoacetic acid also function as a coalescing aid in the coating composition.
