2300 - Coating/Broadcast System
Rhino™ 2300 is a 100% solids epoxy coating / broadcast system. Rhino™ 2300 has good chemical resistance properties and applies easily over concrete substrate by brush, roller or squeegee.
It is easily mixed using the industry standard 2:1 by volume ratio of resin to hardener. Rhino™ 2300 dries quickly, usually tack free within 4 – 6 hours, and dries to a high gloss with greater color stability than conventional epoxies.
Features and Benifits
• Easy to mix, easy to use & low odor
• 2:1 mixture - resin to hardener by volume
• Working time 25-30 minutes
• Highly resistant to cratering or blush
• Applies over concrete with a brush, roller, trowel or squeegee
• Recommended for chip or quartz broadcast, clear coats, aggregate filled or slurry binder applications
Applications
• For clear or pigmented concrete floor coatings and epoxy/aggregate filled systems
• When pigmented, it is an excellent usages as a binder for “chip” or aggregate filled thick film coatings
• Highly versatile, medium duty, chemically resistant concrete coating or flooring system curing to a high gloss with excellent cosmetic appearance
• Mineral filled and used as a “flood” coat or squeegee applied system. Also used as a binder for highly filled, trowel applied epoxy mortars
• May be used as a moisture tolerant new to old concrete adhesive

Mixing
A thorough and complete mix is critical. First mix each component separately. Carefully proportion each component at the ratio of 2 parts A (resin) to 1 part B (hardener) by volume and mix for 3 – 5 minutes. No stripes or color variation should be visible in the mix. When used as a neat coating or chip/aggregate broadcast system, mix no more material than may be applied in 20 minutes.
