Benefits of a Heat Cured Coating

The resin systems of a heat cured coating will typically yield greater performance properties (e.g., Operating Temperature Range, Corrosion Protection, Wear Life, Load Carry, Chemical and Fluid Resistance) than an air dry coating.

General Tips and Cautions:

None of our coatings should be baked in anything other than a Class A oven, which is specially designed for flammable or combustible materials. Use of any other type of oven could result in serious bodily injury or property damage. Ensure the oven is properly vented before starting.
We offer coatings that can be heat cured at temperatures ranging from 250°F to 480°F.  Do NOT choose a coating that will subject metals or other substrates to temperatures that may adversely affect the substrate’s inherent properties.
Start timing when the part reaches temperature, not when the part is placed into the Class A oven, unless otherwise instructed.
Prior to application of the coatings, determine the best surface preparation (phosphate, anodize, etc.) for the substrate and the desired performance characteristics.
Permanent coatings should not be used in conjunction with oils or greases unless field use instructs otherwise.
Sandstrom Dry Film Lubricants are not suitable for surfaces that may contact food or on food-processing or food-handling equipment.

  • 9A

Designed in tandem with the Rock Island Arsenal during the early 1960s, 9A was originally developed for use in weapons support. However, its exceptional wear life, corrosion protection and chemical & fluid resistance properties have earned it widespread use in the industrial market as well. 9A should be used only on substrates that can withstand the necessary high baking temperatures.

9A is listed on PRI’s aerospace QPL for SAE AS5272 Type II, Formerly MIL-L-46010 Type II.

Cure Time: 1 Hour          Cure Temp: @ 400°

  • #099

When stringent environmental regulations or substrate temperature limitations preclude the use of other Sandstrom Dry Film Lubricants, use #099 as a lead-free, low-VOC waterborne, low curing temperature coating option. Offering wear life, corrosion protection and chemical & fluid resistance properties comparable to those of 9A and LC-300, #099 is known to be applied even to components of advanced multi-role fighter aircraft designed for all-weather climates.

#099 is listed on PRI’s aerospace QPL for SAE AS5272 Type III, Formerly MIL-L-46010 Type III.

#099 is listed on the United States’ Dept. of Defense QPL for MIL-PRF-46010 Color 1, NATO Code S-1738. A qualified MIL-PRF-46010 Color 2 is not currently available from Sandstrom or any other manufacturer. Please see our FAQs for more information on Color 2.

  • LC-300

The advanced resin system in Sandstrom’s LC-300 is proven to offer superior corrosion protection, longer endurance life and a broader operating temperature range over comparable competitor products, which is likely why it was chosen for application on the landing gear of the space shuttle fleet. LC-300 should be used when the substrate cannot withstand the baking temperatures of 9A.

LC-300 is listed on PRI’s aerospace QPL for SAE AS5272 Type I, Formerly MIL-L-46010 Type I, Formerly MIL-L-8937.

  • Hi-T 650

Providing a broader operating temperature range than our other stock Dry Film Lubricants, Hi-T 650 can withstand temps up to 750°F and intermittently to 1200°F. Hi-T 650 offers curing versatility – it can be either air dried or heat cured at numerous time/temp combinations; however, heat curing at the time/temp listed above offers maximum cure for highest performance to reduce galling and wear.

Each batch of Hi-T 650 is tested in accordance with and qualified to PWA 550.

  • 9A-XF

Similar to 9A in its performance properties, 9A-XF’s altered makeup provides higher viscosity and extra fine particles of molybdenum disulfide. Sandstrom 9A-XF is specially designed to be used as a protective coating for heavy machinery or other components that require a sacrificial break-in coating for operational startup and excessive wear early in the life of the components. Users of this product like that it quickly develops a burnished film due to the small particles of MoS2, which assist in reducing the coefficient of friction between contact areas in the early life of the application.

  • PTFE AND MOLY / PTFE BLEND COATINGS

  • Poxylube® #887

One of the most recent additions to the Sandstrom Dry Film Lubricant line, Poxylube® #887 provides a unique satin texture with a highly attractive smooth finish achieved in an accelerated cure time of only 20 minutes. The handsome finish on this PTFE product does not deter from its strong performance characteristics in adhesion, hardness, slip resistance and chemical resistance (including resistance to Skydrol).

Potential applications for Poxylube® #887 include latch mechanisms, fasteners, magazines, conveyor belt chutes, easily cleanable paneling for computer cases or office equipment, permanent mold release, air pump pistons, laboratory equipment, tools, brake caliper assemblies, motorcycle foot peg assemblies, air filter enclosures, fan blades and boxes, clip boards, air hockey tables and parts containers.
