Coating compositions for coating fluid handling components, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of a fluid handling component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

The present invention is directed to the use as a reactive component in the curing of compositions based on epoxy resins of a functionalized α-angelica lactone (XOMAL) having the general formula: ##STR00001##
wherein: R.sup.a is a C.sub.1-C.sub.30 alkyl, C.sub.3-C.sub.30 cycloalkyl, C.sub.6-C.sub.18 aryl or C.sub.2-C.sub.12 alkenyl group.

An epoxy resin mixture which contains an epoxy resin represented by Formula (1) below and an epoxy resin represented by Formula (2) below at a weight ratio of 1:5 to 1:0.2. (In Formula (1), plural R1's each exist independently and represent a hydrogen atom or a C1-10 alkyl group, n represent a real number of 1 to 10, and G represents a substituted or unsubstituted glycidyl group.) (In Formula (2), plural R2's and R3's each exist independently and represent a hydrogen atom or a C1-10 alkyl group, n represents a real number of 1 to 10, and G represents a substituted or unsubstituted glycidyl group.)

This invention provides a polymer, which is preferably a polyether polymer. The polymer may be uses in coating compositions. Containers and other articles comprising the polymer and methods of making such containers and other articles are also provided. The invention further provides compositions including the polymer (e.g., powder coatings), which have utility in a variety of coating end uses, including, for example, valve and pipe coatings.

A rubber composition exhibiting an improved processability/stiffness compromise is based on at least a diene elastomer, a reinforcing filler, a crosslinking system, between 1 and 30 parts by weight per hundred parts by weight of elastomer, phr, of an epoxy resin and between 1 and 15 phr of a specific amine-comprising hardener comprising in particular at least two primary amine functional groups located on at least one six-membered aromatic ring and at least two Ri radicals, which are identical or different, selected from the group consisting of linear or branched C.sub.1-C.sub.6 alkyl radicals, halogens, and ethers, tertiary amines, thioethers, ketones, esters and amides, substituted by linear or branched C.sub.1-C.sub.6 alkyl radicals, the said ring not comprising a hydrogen atom located in the ortho position with respect to the primary amine functional groups.

A bonding material including a phenoxy resin thermoplastic component, and a carbon black filler component. The carbon black filler component is present in an amount greater than 1 wt. %. The carbon black filler converts the phenoxy resin thermoplastic component from a material that transmits infra-red (IR) wavelengths to a material that absorbs a substantial portion of infra-red (IR) wavelengths.

A curable resin represented by General Formula (1). In General Formula (1), R.sub.1 each independently represent a monovalent substituent (an alkyl group, an alkoxy group, a fluorine atom, and the like), m is 0 to 4, n is 0 to 40, and R.sup.2's are each independently a monovalent group including a polymerizable functional group.
