DowAksa CarbonBond™ 300 Fast Cure Saturant Epoxy Resin System
Categories: Polymer; Thermoset; Epoxy

Material Notes: DowAksa CarbonBond™ 300 Saturant Resin System (Fast Cure System) provides a balance of properties most suitable for saturating carbon fiber fabrics predominantly applied to concrete structures as supplemental reinforcement or for the remediation of damaged structures. The low viscosity and thixotropic nature allows for fast and thorough wetting of the carbon fiber fabrics without drainage or sagging on vertical and overhead surfaces. The pot life and cure speed is balanced to allow for multiple applications or layers in a single day. Depending on temperature conditions, the system develops >95% of full properties in as few as 7 days. The system is designed with a user-friendly 2:1 by volume mix ratio, with a colored hardener that makes it easy to identify and assess the thoroughness of the mixing process.
