PROBOND 1100PS

structural-grade, high-strength epoxy paste

High-performance, two-component epoxy adhesive for crack repair, concrete bonding, anchoring, and membrane termination detailing.

PROBOND 1100PS is a premium-grade, two-component epoxy adhesive formulated for structural bonding, crack repair, and anchoring applications. It creates durable, long-lasting bonds between freshly mixed and hardened concrete, masonry, and other substrates. It can also be used as an injection adhesive, binder for epoxy mortars, anchoring compound, or as a membrane termination sealant.
With a 1:1 mix ratio, PROBOND 1100PS delivers a non-sag, high-viscosity consistency ideal for vertical and horizontal applications. Once cured, it forms a dense, impermeable bond with excellent tensile and compressive strength. Compliant with AS/NZS 4020 for contact with potable water, it is suitable for infrastructure, civil, and waterproofing applications requiring high structural integrity.
