Chemically resistant epoxy coatings are used in industrial settings to protect surfaces from damage caused by chemicals, acids and solvents. These types of chemically resistant epoxy systems can withstand prolonged immersion in 98% sulfuric acid and 36% hydrochloric acid as well as many other harsh chemicals and solvents. Chemically resistant epoxy flooring is used in warehouses, garages, factories and plants where corrosive chemicals are stored or handled on a regular basis.
The chemical resistance of epoxy resins is primarily dependent on the crosslinking density of the epoxy matrix. This characteristic is influenced by the resin and curing agent selection as well as by the chemistry of the polymer network. The higher the crosslinking density, the better the chemical resistance of the epoxy. The reactivity of functional groups within the epoxy resin and curing agent is also a key factor.

Epoxy systems that use secondary raw materials as fillers have lower production costs and save primary raw material consumption as well as waste disposal. The most common raw materials used as fillers include recycled sand, pit waste (jute fibre and abaca straw), metal chips, egg shells, wood sawdust, vermiculite, fly ash cenospheres, glass shards and electric arc furnace slag.
A clear, two-component Novalac epoxy primer that offers some chemical resistance. This product is ideal for priming concrete and cement substrates prior to application of a high build chemical-resistant epoxy topcoat. It is low odor and provides excellent adhesion to the substrate.
