摘要:
The present invention is directed to benzoxazine-containing adhesives having high adhesive strength at high temperature. These materials are especially useful in automotive applications, in particular, as adhesives for brake components. Methods of their use are also described.
摘要:
Disclosed is a release on demand type corrosion inhibitor composition for a metal substrate formed from only non-electrically conductive film forming copolymer(s); a nitrogen containing functional group X, where the group X comprises a pyridine, a dihydropyridine, a pyrrole, an imidazole, or a mixtures thereof; and a metallate anion. The metallate anion binds to a nitrogen in the functional group X by ion pairing. A localized rise in pH is believed to cause release of the anion via a protonation/deprotonation reaction and the released anion suppresses the corrosion formation. The coating composition includes no electrically conductive polymers.

A curable coating composition is described comprising (A) a carbamate- or urea-functional compound that is the reaction product of a mixture comprising (1) a compound comprising a carbamate or urea group or a group that can be converted to carbamate or urea, and a hydroxyl functional group that is the reaction product of (a) a compound comprising a carbamate or urea group or a group that can be converted to a carbamate or urea group, and an active hydrogen group that is reactive with a lactone ring or a hydroxy carboxylic acid, and (b) a lactone or a hydroxy carboxylic acid, and (2) a compound that is reactive with hydroxyl groups on a plurality of molecules of compound (A)(1), but that is not reactive with the carbamate or urea groups on compound (A)(1), (B) a compound comprising a plurality of groups that are reactive with carbamate or urea.
摘要:
A coating composition including a first component comprising a compound having appended thereto more than one carbamate functional group, and further including a second component reactive with said carbamate groups, which is a substituted acrylamide compound. The composition is useful as a clearcoating composition in a color-plus-clear composite coating.

The invention consists of a plurality of hinged panels including side rails where the panels on each end are shorter in length than the panels between them. The panel on one end is shorter in length than the panel on the other end. Both end panels are tapered in thickness and in with. The top surface is covered with projects forming rectangular cavities with the top of the long sides higher at the ends than in the mid-section. The bottom surface includes fasteners for removably attaching cleats for gripping slippery surfaces. A variety of cleats are proposed for securing the mat under different conditions. Bracing arms are provided to support the mat in an upright position when it is used as a highway warning marker. The mat is brightly colored for daytime use and the side rails and bracing arms are covered with light reflective material for use during the hours of darkness. The panels are so hinged that one half will fold over the remaining half without interference for storage.
摘要:
Plasticizing resins, aqueous dispersions of cationic resins, and methods of making the same for use in cathodic electrodeposition are disclosed. The resins are formed from reacting a polyoxyalkylenepolyamine, a phenol, and a formaldehyde. The reactants may further include a block building unit derived from a polyepoxide. When used in combination with other conventional electrodepositable resins, deposited films with improved mechanical properties and descreased tendency toward cratering are obtained.
摘要:
What is disclosed is a water-based adhesive composition that is an aqueous dispersion or emulsion of a polymer component having functional groups that are inactive in a reversible manner in the adhesive composition as prepared; and a water-soluble, or water emulsion, or dispersion of a cross linker component having functional groups wherein the functional groups are inactive in a reversible manner in the adhesive composition as prepared. Preferably the adhesive composition has a pH of from 7 to 11 and a volatile stabilizing base component is used to inactivate the functional groups and to provide the pH. The functional groups in the polymer component and the cross linker component are activated when the volatile base is removed during lamination heat treatment. The adhesive composition can be used to adhere a variety of plastic films to metal substrates without reliance on non-water-based adhesives.

Environmental etch resistant coatings are described. The coatings are derived from aqueous, curable coating compositions comprising:(a) a carbamate-functional grafted acrylic polymer that comprises the reaction product of a first acrylic polymer and a second acrylic polymer, with at least one of the first and second acrylic polymers having groups that impart water dispersibility to the grafted acrylic polymer, and at least one of the first and second acrylic polymers having carbamate functionality; and(b) a second component comprising a compound having a plurality of functional groups that are reactive with the carbamate functionality.
