SR3602-28 – Aromatic Polyamide-imide

SR3602-28 is an aqueous version of the 3602 series (NMP solvent) of aromatic polyamide-imide resins, enabling further dilutions with water.

Coatings produced from SR3602-28 provide:

  • Excellent thermal stability (polymer will typically withstand temperature excursions up to 240ºC)
  • High level of chemical resistance
  • Good abrasion resistance
  • FDA compliance

SR3602-28 Product Data

Appearance Viscous Clear Red / Brown Liquid
Viscosity 5,000 – 7,500 mPas @ 25°C
Non-volatiles 27 – 29%
Density ~1.05 g/mL @ 23°C
pH 9-10

These figures are given as a guide. Full specifications available on request.

Applications

SR3602-28 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, “non-stick” cookware, electronics, and other areas. Coatings can be produced from SR3602-28 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

SR3602-28 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.

Storage

In the original sealed container these products have a shelf life of 18 months when stored below 35°C. Solution viscosity may change over time from the value reported on COA. The rate of change depends upon solvent, % solids and storage conditions. The change in viscosity does not affect polymer performance and the material can be used with no performance loss.

Handling

Information on the safe handling of this material is available on the relevant Safety Data Sheet (SDS). Further information is available on request.

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 preregistered as substances. The material, or components, is either on the TSCA inventory list or is exempt from the requirement to be listed.

Committed

The foundation for all partnerships is the relationships we develop and foster with our customers. The customer’s success is our primary objective, and that success is built on a deeply-rooted commitment, at all levels of the company, to safety, quality and success in all aspects of our work.
