PRODUCT 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:
Electronic Potting and Encapsulating Compound
Structural Adhesive
Protective Coating
Fiber Glass/Carbon Impregnating And Laminating Resin
Base Binder Resin

DON'T FORGET OUR EPOXY MIXING KIT!
Our Epoxy Mixing Kit comes with all the necessary utensils and protective gloves needed for mixing, dispensing or applying any of our
MAX EPOXY SYSTEM in one convenient kit.
- Avoid Cross Contamination
- Save Time
- Measure Mix Ratio Accurately By Volume
- Reusable
- Safely Handle Chemicals
Use the included measuring cups to accurately measure the proper amount of Resin and Curing Agent.
The plastic mixing tubs are made from High-Density Polyethylene which can withstand the tenacity of the epoxy resin and curing agent. The paper cups are wax-free and the plastic tub comes with air-tight lids that make it an excellent temporary storage container.
Upon cure, any residue demolds easily from the plastic tubs and can be reused.
As a general practice, protective gloves should be worn at all times when handling chemicals.
Our MAX EPOXY MIXING KIT comes with 5 pairs of Powder Free Latex Gloves to protect the user from direct contact with the epoxy resin system that will reduce sensitization or contact dermatitis
