Use of a polyamine stream as curing agent in epoxy adhesive and flooring applications

摘要

An epoxy composition comprising the contact product of a filler, an epoxy resin and an amine component comprising a mixture of mono-, di-, tri- and tetra-substituted amines of structure 1; ;where R₁ is CH2CH2CH2NH2; R₂, R₃ and R₄ independently are H or CH2CH2CH2NH2; and X is CH2CH2 or CH2CH2CH2, in parts by weight (pbw) of 0-20 pbw mono-substituted amine, 60-95 pbw di-substituted amine, 0-20 pbw tri-substituted amine, and 0-10% tetra-substituted amine. The compositions are useful to produce coatings, adhesives, floorings, composites and other articles.
