摘要:
Waterborne sanitary can coating composition, derived from at least (a) epoxy resin, derived from phenol derivatives and epichlorohydrin, which has been converted into a cationic NH2 containing form by reaction with amine, an amine adduct or ammonia and subsequently has been converted into corresponding ammonium salt by addition of organic acid, (b) a phenol-formaldehyde resin as curing agent, (c) polyketone resin, having a number average molecular weight Mn of at least 500, and (d) water, containing minor amounts of organic solvents. Coated tin plate coils on which said waterborne sanitary compositions have been applied and coated cans, obtained from the coated tin plate coil.
摘要:
The invention relates to thermosetting resinous binder compositions comprising a cationic resin (1) and a cross-linking agent (2), wherein the cationic resin (1) is an epoxy resin/amine adduct with on average more than one primary amine group, and the cross-linking agent (2) is a polyketone with on average more than one 1,4-dioxobutylene groups in the backbone. The invention also relates to the preparation of these compositions, and their use in general and in CED more particularly.
摘要:
The invention relates to re-mouldable cross-linked resins and methods for preparing them. Provided is, inter alia, a re-mouldable cross-linked resin comprising polymer chains which are connected to one another via Diels-Alder adducts obtainable from a dienophile and a substituted furan wherein the substituted furan is obtainable by reacting an amino furan compound with a copolymer of carbon monoxide and an olefinically unsaturated compound.
摘要:
Polymeric amines are provided that have N-substituted 2,5-pyrrolediyl groups incorporated in the backbone wherein the N-substituted 2,5-pyrrolediyl group may be represented by the general formula (I) ##STR1## wherein R independently represents a hydrogen atom or a hydrocarbyl group and wherein B represents the substituent containing at least one primary amino group.
