METHOD OF BONDING SUBSTRATES OF GLASS FIBER-REINFORCED POLYESTER RESIN

The present invention relates to a process for bonding substrates of glass-fibre reinforced polyester resin (SMC or BMC) at room temperature without pretreatment, using adhesives which contain an isocyanate prepolymer a), an isocyanate-reactive component b) and a catalyst for the reaction of a) and...

Beschreibung
Zusammenfassung:	The present invention relates to a process for bonding substrates of glass-fibre reinforced polyester resin (SMC or BMC) at room temperature without pretreatment, using adhesives which contain an isocyanate prepolymer a), an isocyanate-reactive component b) and a catalyst for the reaction of a) and b), a compound of the formula being contained as catalyst, in which R , R , which are identical or different, represent alkyl with 1 to 4 C atoms, especially methyl and ethyl, R represents a CHO radical or H, or alkyl with 1 to 4 C atoms, if required substituted with a CHO radical, n represents an integer from 2 to 4, o represents 1 or 2, p represents 0 or 1, o + p = 2.
