Simpson CILPL3KT CI-LPL Long Pot Life Structural Injection Epoxy (3-gal. Kit) by Simpson Strong-Tie is a two-component, high-modulus, high-solids, moisture-tolerant epoxy specially designed for pressure injection, gravity feeding, and flood coat filling of concrete cracks when substrate temperatures are between 60 deg.F (16 deg.C) and 110 deg.F (43 deg.C). This 3-gallon bulk kit delivers a structural-grade repair that chemically bonds with concrete, seals cracks from moisture intrusion, and protects embedded rebar from corrosion - making it an essential solution for demanding structural concrete repair applications.

Key Features

• Meets the requirements of ASTM C881 & AASHTO M235, Type I/IV, Grade 1, Class C
• Chemically bonds with the concrete to provide a structural repair; CI-LPL seals the crack from moisture, protecting rebar in the concrete from corrosion
• Moisture-tolerant, can be used on dry and damp surfaces
• Low surface tension at elevated temperatures allows the material to effectively penetrate narrow cracks
• Formulated for maximum penetration under pressure
• Suitable for pressure injection or gravity-feed applications
• Can be used with metered pressure-injection equipment
• Formulated for use in hot environments to 110 deg.F
• Non-shrink, resistant to oils, salts and mild chemicals, and freeze-thaw resistant
• 3-gal. kit

Frequently Asked Questions

What temperature range is CI-LPL Long Pot Life Structural Injection Epoxy rated for?

CI-LPL is formulated for use when substrate temperatures are between 60 deg.F (16 deg.C) and 110 deg.F (43 deg.C), making it well-suited for hot-weather structural repair applications where standard epoxies may not perform adequately.

Can CI-LPL be used on wet or damp concrete surfaces?

Yes. CI-LPL is moisture-tolerant and can be used on both dry and damp surfaces, as well as for underwater pressure-injection applications, without compromising bonding performance.

What crack widths is CI-LPL designed to repair?

CI-LPL is formulated as a low-viscosity epoxy (2,000 cP) capable of repairing fine to medium width cracks ranging from 1/64" to 1/4" (0.4-6 mm) in width. Its low surface tension at elevated temperatures allows effective penetration into narrow cracks.

What is included in the 3-gallon bulk kit?

The 3-gallon bulk kit (CILPL3KT) includes two 1 US gallon (3.8 L) cans of Component "A" (CILPL1A) and one 1 US gallon (3.8 L) can of Component "B" (CILPL1B), providing a complete two-component epoxy system ready for use with metered pressure-injection or gravity-feed equipment.
