Thixotropic Epoxy Segmental Bridge Adhesive
Estobond PCA is a two component, solvent free epoxy resin system consisting of a white resin and black hardener in pre- measured quantities for easy on-site mixing. Estobond PCA has been specially formulated to meet the requirements for bonding prefabricated concrete bridge segments.
Estobond PCA is used for bonding prefabricated concrete bridge segments to provide a structural and water resistant joint. Estobond PCA is also suitable as a gap filling paste, grouting of starter bars, holding down bolts, etc, where a paste consistency materials is required.
All surfaces to be treated must be firm, dust-free and clean.
