ChemShield 1643

ChemShield 1643 is an internal lining designed for corrosion control and abrasion resistance in chemical plants, and any other areas requiring excellent chemical resistance in immersion conditions. It can be spray applied at 20-125 mils depending on the extent of corrosion.

TECHNICAL DESCRIPTION

ChemShield 1643 is a thick-film, 100% solids, internally reinforced, proprietary formulated lining designed for corrosion control and abrasion resistance in chemical plants, and any other areas requiring excellent chemical and abrasion resistance in immersion conditions. ChemShield 1643 may also be used for restoration and leak prevention of storage tank bottoms and pipelines. ChemShield 1643 is spray-applied from 20–125 mils DFT depending on the extent of corrosion, and is flexibilized to reduce coating stress resulting from mechanical and physical forces exerted on the substrate. ChemShield 1643 is a two-component system; Resin and Hardener. ChemShield 1643 is available in a 30 mil, 60 mil, or 125 mil formulation and will hang on vertical surfaces at those application thicknesses in a single multi-pass coat.

TYPICAL USES

• Steel and fiberglass storage tank bottoms or pipelines
• Pipe internals carrying slurries & abrasive mixtures
• Pipe externals (protection for buried pipelines and directional drilling operations)
• Chemical process floors & concrete containment areas
• Pulp and Paper Services

BENEFITS

• Fast Turnaround time (Cures in 12-14 hours at ambient temperature)
• Superior wide range chemical resistance
• High abrasion resistance
• Flexible to reduce coating stress caused by “oil canning” effects
• High-build, easy to install monolithic application process (20-125 mils DFT)
• Excellent adhesion to steel, concrete and fiberglass substrates
• Low cured shrinkage
• VOC compliant

APPLICATION DATA SUMMARY

See Application Instructions for complete information on surface preparation, equipment, environmental conditions, application procedures, and safety precautions. For conditions outside the specifications or limitations described, contact Wolverine Coatings Corporation for details.

SURFACE PREPARATION

Coating performance is directly related to the quality and degree of surface preparation. Prior to overcoating, all surfaces must be clean, dry, undamaged, and free of all contaminants. For more specific information, consult the surface preparation section contained in the Application instructions.

SAFETY PRECAUTIONS

Read the Safety Data Sheet carefully before use. Safety precautions in the SDS should be carefully followed during storage, handling and use. Improper use and handling can be hazardous to health and cause fire or explosion.
