Ultra-Guard® TB 158 is a two-component, high-strength, low-viscosity structural epoxy designed to be used as a waterproofing membrane in the most challenging negative side applications. The low viscosity makes this an ideal product for crack penetration, gravity feed, or patching. It can be used as a liquid binder for sand, aggregate, or other mineral fillers to form cost-effective material to fill annular spaces. The resin cures in the presence of moisture, making it suitable for repair of the most challenging water penetration failures. The high compressive and tensile strength of this epoxy provide structural strength and can be combined with either Ultra-Guard® Carbon Wrap or Ultra-Guard® Glass Wrap for reinforced systems. The resin also provides excellent durability and chemical resistance. The convenient 2:1 volumetric mix ratio is user friendly. Ultra-Guard® TB 158 is a 100% solids formulation with low toxicity and low odor during cure.
Uses:
• As a waterproof coating for negative side applications on CMU and concrete substrates
• As a binder mixed with sand or pea gravel to fill annular spaces for repair
• In conjunction with glass and carbon scrims to make reinforced systems and crack repairs on walls
• Can be thickened with silica (Cabosil, Aerosil) to make mastics for crack fill and heavy coats for vertical hang strength
Advantages:
• High strength, high modulus, low-viscosity structural adhesive and impervious coating
• Moisture insensitive – it cures in the presence of water
• Convenient easy mix ratio, 2:1 by volume
• Can be thickened to apply heavy coats using silica
• 100% solids, VOC free and Butyl Glycidyl Ether (BGE) free
• Nearly odor-free
