Low viscosity for deeper penetration, high strength, two component epoxy adhesive binder. Multipurpose, solvent-free, moisture insensitive general purpose resin adhesive. HT-500 LV conforms to ASTM C-881, Types I and IV, Grade 1, Classes B & C for epoxy resin adhesive. It also meets USDA specifications for use in food processing areas. An excellent epoxy adhesive for use in crack grouting by pressure injection or gravity-feed, and as a general purpose binder for sealing many concrete slab conditions and for making epoxy patching mortars and grouts.

Data Sheet:

  • Pressure-injection for cracks in structural concrete, masonry, wood, etc.
  • Gravity-feed of cracks in horizontal concrete and masonry.
  • Epoxy resin binder for epoxy mortar patching and overlay of interior, horizontal surfaces.
  • Seal interior slabs and exterior above-grade slabs for water, chlorides, mild chemical attack and to improve performance.
  • Grouting bolts, dowels, pins, etc.

To gravity feed cracks:
Pour neat HT-500 LV into  vee-notched crack. Continue placement until completely filled. Seal underside of slab prior to filling if cracks reflect through.

To pressure-inject cracks:
Use automated injection equipment of manual methods. Set appropriate injection ports based on system used. Seal ports and cracks with HI-TECH Structural Gel or HI-TECH Structural Gel Fast. When the epoxy adhesive seal has cured, inject HT-500 LV with steady pressure. Consult Technical Service for additional information.

To seal slabs:
Spread neat HT-500 LV over slab. Allow penetration. Remove excess to prevent surface        film. Seal interior slabs and above grade exterior slabs only.

For use as an epoxy mortar:
Prime prepared surface with neat HT-500 LV. Place prepared epoxy mortar before primer becomes tack-free. Place the epoxy mortar using trowels. Compact and level with vibrating screed or trowels. Finish with finishing trowel. Exterior application may darken with ultra violet exposure.

 

  • Low viscosity.
