Concresive® Paste SPL (Short Pot Life)

Description: A 2-component, 100% solids, non-sag paste epoxy adhesive used for vertical and overhead applications and for horizontal anchoring. Because of its excellent workability, it is recommended where applied loads are short term or of moderate intensity, and for application when the ambient temperature and/or concrete surface temperature is 32–50° F range. It will cure down to 25° F. Because this product provides quick curing in moderate temperatures, it may also be used between 50–70° F when rapid curing is required. It also can be used when bonding to damp surfaces. At temperatures of 32° F or less, care must be taken to assure that all ice has been removed from the surface to be bonded.

Application: Recommended for sealing surfaces prior to epoxy injection. Pinning loose or broken materials, bonding of rigid materials, fairing uneven surfaces and filling gaps and joints, grouting bolts, dowels and rebar into concrete, and for pick-proof security sealant uses.

Applicable Standards: ASTM C-881, Type I & IV, Grade 3, Class A & B.
