Lica-206 Precast Concrete Adhesive
Lica-206A/B Precast concrete adhesive is a two-component modified epoxy adhesive developed
for concrete prefabricated component bonding. It meets the technical requirements of SBA
prefabricated segment splicing adhesive in FIP standard and passed the 90-day wet-thermal aging
durability test. Application include splicing and sealing of prefabricated concrete such as concrete
segmental beams, prefabricated piers, large pipe piles and segments.
