Description
MAX MCR BLACK A/B is an unfilled medium working time casting resin that offers a good balance of performance and cost, making it an excellent resin for electrical insulating applications. It cures to a hard but tough compound that is suitable for small 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.
MAX MCR BLACK A/B is low in viscosity and offers a very high gloss finish blemish free surface.
The 2 to 1 mix ratio offers ease of use and easily poured in place or can be adapted for mix meter equipment.
It is suitable for silicone, polyurethane, steel, and wood molds for casting applications.
MAX MCR A/B can also be utilized in many different applications where epoxy resins are typically employed.
It bonds very well to wood, metal, concrete and other composite and plastic substrates.
Other Uses:
