Description: CCS Coating, Epoxy Healer Sealer is a very low viscosity, solvent-free, two-component epoxy resin system for topical application on porous and/or cracked concrete. Blended in the proper proportion, Epoxy Healer Sealer is converted to a hydrophobic polymer, resistant to water, deicing solutions and automotive fluids. Typical applications include gravity filling of fine cracks, reconsolidating distressed areas and strengthening of weak and porous surface layers. The product may also be used as primer in flooring applications. The low odor, low volatility and high flash point minimize job site risks and make possible application in congested urban areas.

Features: Low viscosity enhanced with surface active additives to lower surface tension and achieve deep penetration. Fast cure minimizes downtime and traffic disruption. Low odor and low volatility. High flash point. Resistant to water, salts and automotive chemicals. No VOC solvents.

Limitations: Concrete surfaces must be dry. Minimum installation and cure temperature is 500 F. Do not apply on concrete subject to hydrostatic pressure or at substrate temperatures above 1200 F. Do not change recommended proportions when blending the components of the product. The daily temperature cycle of the substrate may cause outgassing and resist penetration of the material.

Colors and Packaging: Clear, light amber. Standard package unit sizes are 5 and 50 gallons.

Shelf Life: 9 months minimum in unopened, original containers when stored between 40 and 900 F and away from direct sunlight.

Chemical Resistance: Resistant to a wide range of commonly used deicing and automotive chemicals. Limited resistance to alcohols and hydrocarbon solvents.

Surface Preparation: Substrate surfaces must be clean, dry, sound and free of all bond inhibiting substances. Prepare surfaces by abrasive blast removal of asphaltic and petroleum products, concrete curing seals and other coatings followed by by manual or power sweeping the entire surface to be treated. Blow loose material from visible cracks using oil free, high pressure air blast. Exposed steel should be cleaned to "white metal" according to SSPC SP 5-63.

Mixing: CCS Coating, Epoxy Healer Sealer is a two component system. The resin to hardener (Part A : Part B) ratio is 4:1 by volume. Wear safety glasses and clean Neoprene rubber gloves when handling the materials. Consult MSD sheet for recommendations on respiratory protection. Transfer appropriate quantities of Part A and Part B into a mixing container. Use smallest quantities feasible to maximize penetration after application before the potlife of the mixed material expires. Blend thoroughly for approximately 1 minute using a Jiffy mixer attached to a low speed (350 to 750 rpm) electric or pneumatic drill.

Installing: Pour the mixed material onto the substrate and distribute with a squeegee to a coverage rate of approximately 100 to 125 ft²/gal. Let the material penetrate for 10 minutes and then redistribute the excess with squeegees or a broom leaving the minimum amount of material possible on the surface. Repeat the process if the material is rapidly absorbed. Wait a minimum of 20 minutes and broadcast dry, #20 mesh blasting sand at a rate of approximately 2 lb/yd². Remove excess sand by vacuuming or sweeping prior to opening of traffic. Do not open to traffic until the treated surface is tack-free (non-oily)and sand cover adheres sufficiently to resist brushing by hand.
