E2U Epoxy 6150RC (Rapid Cure) is a 100% solids epoxy primer and basecoat in one. Ideal for One Day flake systems. E2U 6150RC is fast curing despite its epoxy chemistry, 0 VOC, and designed as a base coat for colour flake (chip) and other broadcast media. 
 It can be applied to new and existing concrete and has a low viscosity. 6150RC provides excellent adhesion and hide to concrete in a single coat application.

E2U 6150RC withstands up to 9 lbs of Moisture Vapor Emissions. Reducing the need for additional moisture barriers. Full Broadcast of media, such as flake (chips), is required to apply for the adhesion warranty. E2U 6150RC adheres to damp or dry concrete and gives ample open time for broadcasting flakes (chips) and other media.

6150RC Key Features:

Preparation 

Concrete

Concrete should be at least 28 days old before coating. Remove all laitance, release agents, curing compounds, oil, grease, failing coatings, dust, dirt and other surface contaminants. Fill any large cracks or voids using Epoxy2U Polyurea Crack Repair or other suitable approved filler. The surface should be profiled via diamond grinding or shot blasting to ensure maximum adhesion. Moisture content of the slab should be below 5.1% (not RH), otherwise a moisture vapor barrier, such as Epoxy2U MVB15 should be applied prior to 6150RC.
Note: Mechanical preparation is the preferred method of preparing concrete for coating application. Shot-blasting, diamond grinding, scarifying and scrabbling are all acceptable methods. DO NOT ACID ETCH. EPOXY2U Australia, and its sales agents, will not be responsible for coating failures due to undetected moisture vapor emissions.

Coating performance is directly proportional to the comprehensiveness of surface preparation. 

Mixing and Application

The ratio of E2U Epoxy 6150RC is 2 to 1. That is, two parts A (resin) to one part B (hardener) by volume. Mix these with a drill and mixing paddle. Note: If using a drill mixer, use a low speed (aim not to exceed 300 rpm) to prevent air entrapment.
1. Premix 1.33 gallon of Part A for 30-45 seconds.
2. Add 0.67 gallon of Part B into 2gal pail (Part A) and mix for another 60-90 seconds. Be sure to stop briefly to scrape the sides of the mixing container to ensure components are completely mixed together. 
3. E2U 6150RC is designed to be immediately poured on the floor.
The Pot life is less than 5 minutes. Once poured out on the floor, 15-20 minutes of working time can generally be expected.

Application:
Application of 6150RC for a one coat primer/base for broadcast is typically applied at 8 mils (200microns). For estimation purposes, use 40 - 45 m2 per 2 gallon kit. 
NOTE: This product is designed to be used at a Primer/Broadcast coat. Ideally must be broadcast to refusal, or top coated with another coat of pigmented 100% solids epoxy or other pigmented top coat.
1. Always aim to apply in descending temperatures, where possible. Concrete is porous and traps air. In ascending temperatures (generally mornings) the air expands and can cause out gassing in the coating. It is safer to apply coatings in the late afternoon, especially for exterior applications.
2. Optimum ambient temperature should be between 13-33°C during application. Note: Cure times are affected by ambient and slab temperatures. Temperatures of 13°C and lower can slow cure times. Temperatures of 33°C and higher will speed up working and times.
3. Mix 2gal kit of Epoxy 6150RC using above mixing instructions.
4. Apply approximately 20 m2 per gallon by immediately pouring out on surface in a ribbon, while walking and pouring at the same time until bucket is empty.
5. Using a squeegee on a pole, pull the 6150RC over the substrate. As a coat over bare concrete, squeegee and back roll aiming to no exceed 20 m2 per gallon (approx 5.3 m2 per litre).
6. Be sure to use an 460mm, 11mm NAP, non-shedding phenolic (plastic) core paint roller cover when back rolling the product from side to side to ensure 100% coverage and evening out of product.

Broadcasting:
Flake:
1. Following Step 6 above. Broadcast Flakes/Chips (at 2-2.2 kg per m2) by tossing them into the air and allowing them to gently rain down into the wet resin.
2. For a partial broadcast DO NOT use 6150 Epoxy, use pigmented polyaspartic85/RC instead and broadcast approx 500g of chips per 10m2.  Contact E2U AU for more detail.
3. Allow to cure (walking). Then scrape the basecoat with a drywall scraper in all directions, typically at least two (N to S, E to W). Vacuum to remove broken and small pieces of flake and any dust.

Silica Sand or Quartz Broadcast: 
1. Following Step 6 above, gently throw the silica sand up into the air, allowing it to fall without lumping in one spot or moving the resin. Do this until the floor is totally saturated with the silica sand and the resin will not accept any more. This generally requires 2 to 2.5kg  per m2. Allow to dry for 2- 4 hours.
4. Sweep floor and stone any high spots.

Following either method, apply a seal coat of E2U Polyaspartic 85/RC or WB Urethane. Allow for up to 30% greater clear coat consumption than over flake when applying over sand / quartz.
