CT-500 coated die cast aluminum medical lab tanks (top) and 36" and 2" diameter die cast ductile iron valve components (bottom).

Advantages

• An ideal acid resistant lining for pumps, valves and pipe.
• As a release coating, provides the advantages of Teflon yet with increased durability.
• Ideal as a permanent mold release for rubber, urethane, epoxy and other materials.
• Complies with U.S. Food & Drug Administration regulation 121.2621 for food contact (CT-500, CT-510) and is approved for use as a food contact coating.
• Adaptable to thickness of 10 to 20 mils by the application of multiple coats and/or hot spraying of slurry.
• Ideal protective coating for metals exposed to aggressive environments.
• Excellent adhesion for ferrous and non-ferrous metals.
• Outstanding chemical resistance; one cured, there are no known solvents below 500°F.
• Outstanding thermal shock stability; maintains performance characteristics after repeated thermal cycling; no shrinkage, degradation of coated material.
• Superior resistance to impact and abrasion.
• Excellent salt spray and marine protection.
• Available in a range of formulations that permit wide spectrum of properties while retaining chemical resistance.
• Single or multiple coats: dry film coating thickness from 1 to 5 mils per coat.
• Applies readily with conventional spray equipment.
• Cleans up easily with water.
• Indefinite shelf life in sealed container.
• Cost-efficient: greater coverage, protection with less coating thickness.
• Electrically conductive coating CT-520 combines durability and corrosion resistance.
  
  
  

Applications

Unless other wise noted, all CT-500 coatings are suitable for the following applications:

• Pumps, valves, piping, tanks: ideal acid-resistant lining.
• Permanent mold release coating: for rubber, urethane, epoxy and other materials.
• Primer: (CT-500) in conjunction with CT-510 or other coatings/adhesives for additional corrosion-resistance performance.
• Food processing plants: suitable for meat packing, dairy and other food processing applications.
• Release coating for cookware: interior cooking surfaces of top-of-stove cookware and self-heated electrical appliances. Non stick performance of Teflon^®, but with greater durability and scratch resistance.
• Automotive: low friction, wear-resistant coating for fuel control cam rings.
• Mining: protects valves, expansion joints in pipes.
  
  
  
  

Technical Data

Packaging, Storage and Handling

• Packaging: Quart, gallon, five-gallon containers.
• Shelf Life: Indefinite in sealed container.
• Surface Preparation: Remove all oil, dirt, grease and other contaminants with appropriate solvent; prepare surface by grit blasting or heat oxidation.
• Application: Mix thoroughly and apply at room temperature with conventional spray equipment. Multiple coats of CT-500 or CT-520 may be applied; however, CT-510 must be applied in one coat.
• Primer: Steel: Not generally required. Aluminum: Not required. Copper, brass, some other metals: Inorganic aluminum primer.
• Curing:
  • CT-500: 1st coat @ 650°F for 20 minutes; 2nd coat @ 700°F for 30 minutes.
  • CT-510: 725°F for 10 minutes (Do not exceed one coat).
  • CT-520: Each coat @ 700°F for 30 minutes.
• Clean up: Excess uncured material may be removed from tools or other surfaces with water.
• Safety: Handle in accordance with materials safety handling instructions.
