Chemical & Pharmaceutical
Coatings with proven chemical resistance for environments where acids, bases and solvents coexist with strict regulatory requirements.
Environments that destroy the wrong coatings
Chemical and pharmaceutical plants combine continuous exposure to mineral and organic acids, concentrated bases, solvents and oxidizing agents with regulatory requirements that define which materials may contact the product. A coating without adequate chemical resistance does not just fail prematurely - it can contaminate the process, cause non-conformance with ANVISA or FDA and compromise asset integrity. Sherwin-Williams P&M specifies systems with the right combination of chemical barrier, substrate adhesion and regulatory compliance.
Applications by environment type
Tanks and reactors - strong acids
Epo-Phen® phenolic or novolac epoxy for immersion in HCl, H₂SO₄, HNO₃ and acid blends - with minimum DFT specified per acid type and concentration.
Tanks and reactors - bases and alkalis
High-solids epoxy systems with alkaline resistance - for NaOH, Ca(OH)₂ and hot CIP cleaning solutions.
Chemical process room floors
Resuflor™ or Poly-Crete® depending on product type and service temperature. Expansion joints and drains specified with compatible material.
Pharmaceutical environments - cleanrooms
Smooth, semi-gloss epoxy finish with no texture - easy cleaning and disinfection with isopropyl alcohol, quaternaries and vaporized H₂O₂.
Facades and external structures
Macropoxy® + Sher-Loxane® to protect structures in environments with acid mist, solvent emissions and C3/C4 weather exposure.
Containment dikes and bunds
Systems resistant to hazardous chemical spills - assessed according to the product's chemical composition and containment volume.
Key products
Epo-Phen®
A leading chemical barrier for immersion in organic and inorganic acids, solvents, alcohols and alkaline solutions - verified in extended immersion testing.
