Maxkote M-CHEM 300 is a high-build, solvent free Epoxy Novolac Coating providing excellent resistance to a wide range of concentrated acids and industrial chemicals.

The material is suitable for a variety of applications including as a lining for bunding and secondary containment or as an internal lining for process equipment such as pressure vessels operating below 60°C.

M-CHEM 300 – Acid Resistant Epoxy Novolac Coating is proven to protect against Sulfuric Acid 98%, Hydrochloric Acid 36%, Phosphoric Acid 75% and Hydrobromic Acid 40%.

Typical Uses

• Acid Resistant lining for Process Columns
• As a Chemical Storage Tank Lining
• To protect Bunds & Containments from chemical attack

Application

Steel

• All oil and grease must be removed from the surface using an appropriate cleaner such as MEK or similar type solvent.
• All surfaces must be abrasive blasted to ISO 8501/4 Standard SA2.5 (SSPC SP10/ NACE 2) minimum blast profile of 75 microns using an angular.
• Once blast cleaned the surface must be degreased and cleaned using MEK or similar type solvent.
• All surfaces must be coated before gingering or oxidation

Concrete

Existing Concrete

• If the concrete surface is contaminated, pressure wash using clean water.
• Once the concrete is dry, lightly abrasive blast or scarify taking care not to expose the aggregate.
• Clean all dust and debris from the surface and take several moisture readings and prime with M-PRIME 100 – Low Viscosity Epoxy Concrete Primer or M-PRIME 104 – Damp Tolerant Concrete Primer dependant on moisture readings obtained.
• Apply M-PRIME 100 or M-PRIME 104 at a target wet film of 150 microns, allow to cure before overcoating.
• For very porous surfaces a second coat of primer may be required.

New Concrete

• Allow new concrete to cure for a minimum of 21 days. Lightly abrasive blast or scarify to remove any surface laitance.
• Clean all dust and debris from the surface and take several moisture readings and prime with M-PRIME 100 – Low Viscosity Epoxy Concrete Primer or M-PRIME 104 – Damp Tolerant Concrete Primer dependant on moisture readings obtained.
• Apply M-PRIME 100 or M-PRIME 104 at a target wet film of 150 microns, allow to cure before overcoating.
• For very porous surfaces a second coat of primer may be required.
