ARADUR® 2965-1 - Gel Time, Curing Speed and Viscosity - 1

Features & Benefits

Product Features
  • In combination with liquid epoxy resins and suitable fillers for tough and hard mortars or mastics. In formulations with a high binder content a degree of residual tackiness may remain, and smearing may occur, particularly at low working temperatures. Under these conditions we recommend the proportional use of rapid hardeners such as Aradur 10, 14, 16.
  • Low viscosity PAA for mortars, adhesives, mastics.
  • General purpose high viscosity unmodified basic liquid epoxy resin based on bisphenol-A.
