ChemEpoxy
Quick Overview
ChemEpoxy is a versatile fast low-temperature curing Novalac epoxy with excellent chemical resistance such as resistance to 98% sulfuric and 37% HCL acids. It provides superior resistance to water spotting, even under adverse conditions, and is DOT noncorrosive. This material is used in industrial flooring, chemically resistant tank linings, chemical handling equipment, chemical storage vessels and marine environments. It is used on metal, wood, fiberglass, concrete, masonry and other difficult to coat low temperature surfaces requiring a tough chemical resistant coating.
ChemEpoxy is 2-component mixture which may be applied using roller, brush or low-pressure pot spray. This material is to be used directly on clean dry contaminant-free surfaces and becomes tack free within 1 hour depending on ambient humidity and temperature. Full cure is achieved under normal drying humidity in 7 days at ambient temperature.
Please contact our technical support group for specific substrate application procedures, equipment, safety gear and clean-up kits. Refer to MSDS for material and safety standard procedures.
Technical Application Data
Application substrates must be dry and clean from contaminates; free of loose rust, paint, moisture, dirt, oils, etc. This material is to be applied within 50°F to 100°F. Mix 1A hardener: 2B resin thoroughly with a hand drill jiffy mixer, sit a couple minutes then remix. Coating may be applied by roller, brush or pressure-pot sprayer. Spraying may require up to 10% solvent such as aromatic 100 or xylene. Working time (gel time) at 75°F is 40 min unless altered by solvent dilution, ambient temperatures and substrate temperature. Recommended max wet per coat application film thickness is 16 mils. Coverage at 16 mils is 100 sq. ft./ mixed gal.

Substrate Surface Preparation
Preparation of substrate surface prior to the application of a SuperSkinSystem is extremely important to achieve proper system bonding.
Concrete must be fully cured and should be prepared with a sandblasting, diamond grinding or machine sanding depending on the severity of the concrete surface condition. Similar proper preparation must be performed for metals. Primers also require this proper preparation. Always power clean using mild detergent prior to sanding, etc. Call TechSupport Group for assistance with selecting SSS application system. Also read the Application Page on this website. If patching concrete, use mineral filled fast-set Acrylic Modified Epoxy applied by trowel. For expansion joints, use Joist Seal applied by hand cartridge dispensing gun. It is always best to perform a test within a small section of the application area prior to full scale engagement.
