Product Data Sheet Composite resin system □ Specially for applications at higher processing Product Benefits ■ Hardener for processing at increased temperature ■ Because of low mixed viscosity at processing temperature (60°C) fast infiltration of dry fabrics □ Glass transition temperatures up to 170°C dependent on curing conditions Basis Two-component-epoxy-system Resin Biresin® CR170, epoxy resin, colourless to yellowish Hardener Biresin®CH170-3, amine, water clear to brownish

■ The material and processing temperatures should be at least 40°C. ■ Before demoulding precuring of at least 3 h at 60°C is recommended. ■ To obtain mechanical and thermical values post curing of 4 h at 160°C (heating rate 10 grd/h) is necessary. ■ To clean brushes or tools immediately Sika Reinigungsmittel 5 is recommended. ■ Additional informations are available in "Processing Instructions for Composite Resins".
