Applications

SR3604-28A is typically used in the following applications:

  • Temperature resistant coatings.
  • Binder for high temperature resistant fiber reinforced plastics.
  • Bonding agent for high temperature applications up to 240°C.
  • FDA compliant coatings.

The excellent chemical resistance of these polymers leads to applications in container coatings, “nonstick” cookware, electronics, and other areas.

Coatings can be produced from SR3604-28A that meet requirements of FDA regulations 177.2450 and can therefore be used in the manufacture of cookware coatings.

Further Dilution

Use de-mineralized or distilled water.

Processing

SR3604-28A is supplied as a solution; care must be taken to enable the solvent to be removed slowly to avoid blistering of the film. During curing, the temperature of the object should be increased slowly up to the final cure temperature to avoid blistering of the coating due to final release of solvent. Final cure temperature of >220°C is required.

It is advised not to mix used material with unused product for storage, although topping-off the process tank with fresh material is acceptable.

Regulatory Information

Specific local inquiries should be directed to Cymer-Dayton, LLC. To the best of our knowledge this product meets the definition of a polymer under REACH, and its components are registered as substances. The material, or components, is either on the TSCA inventory list or is exempt from the requirement to be listed.

Storage & Handling

Shelf Life
18 months
Storage

In the original sealed container these products have a shelf life of 18 months when stored below 35°C. Solution viscosity will increase over time. The rate of increase depends upon solvent, % solids and storage conditions. The increase in viscosity does not effect polymer performance. The viscosity can be adjusted with water or additional solvent and the material can be used with no performance loss.
