Abstract
A resin which may be cured to form a polymeric resin which is diffcultly inflammable and resistant to high temperatures, said resin being a mixture of (a) a resin component comprising at least one thermically curable 1-oxa-3-aza tetraline group containing compound and optionally a curable epoxy compound; and of (b) a second component comprising at least one flame retardant selected from the group consisting of: aluminum hydroxide; hydrated calcium magnesium carbonate; magnesium hydroxide; element red phosphorus, oxygen acids of phosphorus; inorganic salts of oxygen acids of phosphorus; organic salts of oxygen acids of phsophorus; polyphosphates; boric acid; salts of boric acid.
