INSULCAST 7285
SELF-EXTINGUISHING EPOXY COMPOUND FLAME CLASS 94V-0

DESCRIPTION

INSULCAST 7285 is a low viscosity, self-extinguishing, general purpose epoxy potting/casting compound which will cure at room temperature to a semi-rigid, thermoset polymer. It has excellent physical and electrical properties. This product is similar to INSULCAST 333 with slightly different flame retardants. When used with INSULCURE 121 provides good leveling characteristics with superior flame resistance. U.L. Recognized 94V-0.

USE INSTRUCTIONS:

  1. Premix INSULCAST 7285 in original container being certain to reincorporate any fillers that may have settled.
  2. Weigh out required amount of INSULCAST 7285.
  3. Weigh into INSULCAST 7285, the proper amount of curing agent according to the ratios indicated.
  4. Mix thoroughly, being careful to scrape sides and bottom of container to ensure proper blending.
  5. Evacuate for 2-5 minutes if void-free castings are required.
  6. Pour into cavity or mold.

CURE SCHEDULE:
Insulcure 121:40-50 gram mass : 45 mins. at 38°C or 15-20 mins. at 100°C.
100-200 gram mass: 45-60 mins at room temperature then 1 hr at 100°C
Larger than 200 grams: 12 hours at room temperature then 1 hr at 100°C or 24 hours at room temperature.
Insulcure 11B:2 hours at 100°C, (212°F) for masses less than 1/2 lb.
For masses above 1/2 lb. cure 2 hours at 80°C, (177°F)plus 2 hours at 100°C (212°F).
For optimum high temperature properties, post cure 1 hour at 150°C (302°F).

STORAGE REQUIREMENTS:
