MAX MCR A/B
POTTING RESIN FOR ELECTRONICCIRCUITBOARDS
48- FLUID OUNCES COMBINED VOLUME
1 Quart Of Resin (32 Fluid Ounces)
And
1 Pint Of Curing Agent (16 Fluid Ounces)
PRODUCT DESCRIPTION
MAXMCR BLACK A/Bis an unfilled medium working time, low viscosity potting compound resin system for embedding or encapsulating printed circuit boards (PCB), relays, coils, and other electronic or electrical circuitry. MAX MCR A/Bis low in viscosity and is room temperature cured. It is mixed 2:1 by weight or by volume and provides a 30 minute working time (200-gram mass @ Upon cure, MAX MCR is completely noon electrically conductive offers a very high gloss finish blemish free surface. It cures to a hard but tough compound that is suitable forsmall to medium parts without excessive exothermic heat generation (up to 1 pound). It has a 30-minute working time when mixed up to 200-gram mass.
The2 to 1 mix ratio offers ease of useand easily poured in place or can be adapted for mix meter equipment.
MAX MCR A/B bonds to PVC, PP, ABS, Plastisol, aluminum, steel, copper, brass and other materials typically used in electrical circuits.
