Sikadur-330 — Thixotropic Epoxy Impregnating Resin for SikaWrap Structural Fabrics
Sikadur-330 is a 2-part, thixotropic, epoxy-based impregnating and laminating resin designed specifically for SikaWrap structural strengthening fabrics. It serves as impregnating resin (dry application method), substrate primer (wet method), and structural adhesive for bonding Sika CarboDur plates, NSM profiles and SikaWrap FX anchorage cord.
Key Features
Easy to mix
Application by trowel and impregnation roller
Formulated for manual saturation methods
Thixotropic — good application properties for vertical and overhead surfaces
Good adhesion to many substrates
High mechanical properties
No separate primer required
Applications
SikaWrap fabric impregnation and laminating (dry application method)
Substrate primer for wet application method
Structural adhesive for Sika CarboDur plates
