405 - Structural Gel

Rhino™ 405 Structural Epoxy Gel is a highly versatile, 100% solids high build system. Its wide variety of uses on concrete substrate include structural restoration, patching, and adhesive repairs. The long working life of Rhino 405 is ideal for repairing large concrete floors, and restoration of deteriorated concrete structures.

Description

Rhino 405 applications are tack free within 8 – 10 hours, and may be recoated with a variety of Rhino Epoxy products at that time. When mixed at a ratio of 2:1 by volume (yellow resin and blue hardener), the material cures to a light green color, which also ensures a proper mix. Rhino 405 provides excellent chemical resistance and is highly moisture tolerant. These features make Rhino 405 ideal for wastewater applications.

Features & Benefits

Easy to use 2:1 by volume mixing

Surface Preperation

Surfaces must be structurally sound and free from contaminants such as dust, oil or dirt. Sand or sweep blasting, by other means of mechanically abrading achieves the best bond. All freestanding water must be removed. General surface preparation and application procedures specified in ACI 503.1-4 should be followed.

Mixing

A thorough and complete mix is important. Due to the gel consistency of Rhino 405, the use of a slow turning and heavy duty Jiffy or mixing paddle is recommended. Carefully proportion each component at the ratio of 2 parts A (yellow resin) to 1 part B (blue hardener) by volume and mix until a consistent light green color with no stripes or color variation visible in the mix. It is recommended that Rhino 405 be mixed in smaller batches, and used within 45 minutes from time of mix. Due to the product’s gel characteristics, the individual components should be conditioned to a controlled temperature between a minimum of 65˚F and a maximum of 90˚F for best results.

How To Apply / Tips

Mixed material should be applied by trowel, squeegee or putty knife, and feathered at the edges to blend with existing sound concrete substrates.

Temperature and humidity conditions affect the cure and tack free times of this material. Warm, dry conditions speed the cure and cool, damp conditions will lengthen the cure time. Each component should be stirred prior to mixing.
