CIPP - Cured In-Place Pipe

CIPP (Cured In Place Pipe)clients start at the grass roots level with several thousands corporate and independent plumbers performing repairs on home size sewer lines using a no dig technology that forms a pipe within a pipe. Large, municipality and utility scale users are also taking advantage of this technology. CIPP now represents about 25% of the non-wind epoxy sale and is growing every day.

Rhino 1310T-Lt Blue Data Sheet


1310T-LT Blue - Product Description

Rhino 1310T-LT Blue is a 100% solids, non-draining, epoxy system for producing Cured In-Place Pipe. It is a single resin system with multiple choices of either 2:1 or 4:1 (by volume) curing agent hardeners. Rhino 1310T LT Blue epoxy resin is tinted transparent blue, and the hardeners are transparent yellow, so when the system is properly mixed a uniform green color is achieved. Rhino 1310T LT Blue Resin CIPP systems have a proven track record in conjunction with felt or fiberglass liner materials.


Features & Benefits

• Rehabilitates underground pipes
• Cures very fast with mild (120°F) heat
• Trenchless repair of pipes from 2" to 102" in diameter
• Effectively lines pipes and drain lines with a 90-degree bend
• ASTM F-1216 compliant, adding value and assuring quality in the CIPP process



• Applications requiring less invasive pipe system replacement procedures
• Municipal, residential, commercial markets (manholes and underground pipe systems
• Trenchless, less invasive sectional point structural repair without digging
• Lateral and sectional re-lining markets (homes, storm drains and sewer pipes)

Cure Schedule

Allow the composite to cure at the recommended temperature as listed in the physical properties chart (above). In the case of all listed hardeners, allow at least 6-8 hours at ambient (>65°F) or 2-3 hours at 130°F before attempting to return the composite to service. In colder weather (less than 65°F) allow additional time before returning the composite to service.  In all cases, an elevated temperature cure of 2-4 hours at 120°F - 140°F assures the highest quality end product.

Physical Properties

Cured In-Place Pipe (CIPP) applications demand a wide variety of Rhino hardeners which are available with the Rhino 1310T-LT Blue CIPP epoxy resin.

Hardener Recommendations

All hardeners reach sufficient strength for return to service after overnight ambient cure. The fastest Rhino hardener, Rhino 3102, is useful for winter applications, and in smaller applications requiring a fast return to service time. Rhino 3103 is the standard 30-minute system hardener used for 4:1 volume mixing applications. Rhino 3138 should be used in high temp applications (up to 240˚F) and is 4:1 by volume, which is also useful in hot weather and for long or large diameter pipe runs. Rhino 3191 is the standard 1 hour General Purpose curing agent used for 2:1 volume mixing applications.


Rhino CIPP hardeners, 3102, 3103 and 3191 are DOT not regulated / DOT non-corrosive, minimizing hazardous materials shipping issues.

Typical Mechanical Properties

Rhino 1310T-LT Blue resin post cured at 130°F for 4 hours with all listed hardeners are compliant to ASTM F-1216. Listed properties are for typical epoxy/felt liner CIPP applications. Certification to ASTM F-1216 adds value and assures quality for firms using the CIPP process.
