摘要:
A curable coating composition is prepared from two components; (1) a component having more than one epoxide group (an epoxy resin) and (2) a component having more than one group reactive with the epoxy groups of component (1) (i.e., a polyhydric phenol). Either component (1) or (2) is the reaction product of a compound containing at least one primary or secondary amino group and at least one aliphatic hydroxyl group with an epoxy resin and optionally a component reactive therewith. This reaction product containster- minal aliphatic hydroxyl groups and epoxy groups or groups reactive with epoxy groups. The components (1) and (2) are preferably normally solid materials and the coating composition is a powder coating composition.

Liants pouvant être dispersés dans l'eau pour laques électro-phorétiques cationiques à base de résines époxydes modifiées. Les liants sont des produits de réaction: A) de résines époxydes avec un poids moléculaire d'au moins 350, B) d'alcools polyfonctionnels, d'acides carboniques et/ou de liaisons SH avec un poids moléculaire se situant entre 500 et 5000 et C) d'aminoalcools portant au moins un atome d'azote primaire coiffé ou un atome d'azote tertiaire.

A curable composition comprising an epoxy resin or a monoepoxide and a curing agent comprising a metal salt complex of an adduct of an imidazole and a monofunctional epoxy compound.
摘要:
The present teachings contemplate relatively high glass transition temperature (Tg) polymers and/or other reaction products. A method may include reacting a diepoxide with a bisphenol in amounts and under conditions to produce a material that has a Tg as measured by differential scanning calorimetry according to ASTM E1358-08(2014) of at least about 90° C. at [east about 100° C. (at least about 110° C., or at least about 120° C.
