Rhino epoxy composites for infrastructure retrofit are used for seismic upgrade, blast protection and composite repair of conventional concrete/rebar structures that are failing. The infrastructure market segment has grown nearly 100% per year and now represents about 35% of non-wind epoxy sales. An added bonus in this market is that many of its existing epoxy clients can use Rhino Linings urethane formulations.
1310T RESIN FOR COMPOSITE INFRASTRUCTURE
Rhino 1310T epoxy composites are non-draining, 100% solids systems that provide maximum flexibility for a variety of reinforced composites. Whether performing fiberglass infrastructure reinforcement, seismic retrofits, or the repair of failing conventional concrete/rebar structures, Rhino 1310T forms a matrix in which carbon or glass fiber is saturated then woven together to add structural reinforcement.
Rhino fiberglass infrastructure reinforcement and seismic retrofits last longer and incur a fraction of the cost and time it takes to achieve the same results using conventional materials and techniques. Carbon fiber wrap and blast mitigation solutions are currently being used in numerous concrete, masonry, steel, and wood structures to increase strength and durability.
FEATURES AND BENEFITS
- Fast wet-out of fiberglass reinforcements with minimal drainage from lamination
- Greater fatigue resistance, strength and reinforcement
- Flexible carbon fiber wrap conforms to any shape
- Less weight and lower thermal expansion
- Reduced installation time
- Infrastructure seismic upgardes (concrete beams, columns, pipes)
- Carbon fiber or glass filiment winding (pressure tanks, vessels)
- Fatigue resistant FRP manufactured parts
- Composite tooling
- Blast Mitigation
- Construction Equipment
- Bridges and piers
- Fuel tank sealers
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 for the composite to cure.
After the recommended elevated temperature cure, all systems may be exposed to the listed service temperatures. In all cases, an elevated temperature cure of 2-4 hours at 120°F - 140°F assures the highest quality end product.
Liquid and cured physical properties of 1310T with Rhino hardeners:
|RHINO 1310T Composite Resin with:||Hardeners|
|Parts Hardener by Weight||22||22||22||43||20|
|Mix Ratio by Volume||4:1||4:1||4:1||2:1||5:1|
|Gel Time Min (150gr)||12-15||30-35||50-60||60-70||25-30|
|Set Time, Hrs @ 77°F||2||4||5||4||3|
|Cure Time, Hrs @ 130°F||2||3||4||3-4||3-4|
|Shore D Hardness (24 hr room temp cure)||80||78||80||75||85|
All listed hardeners cure very rapidly with the addition of heat, via hot water or hot air at a temperature of 120°F-140°F.
All hardeners reach sufficient strength for return to service or demolding after an overnight ambient cure. The fastest Rhino hardener, Rhino 3102, is useful for winter applications, or for mixing in smaller batches. 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 or for large areas. Rhino 3191 is our standard 1 hour General Purpose hardener, and may be certified to NSF Standard 61 for potable water.
Rhino 3136R-1 is used for composite tooling. Rhino hardeners, 3102, 3103 and 3191 are DOT not regulated / DOT non-corrosive, minimizing hazardous materials shipping issues.
