PRODUCT DESCRIPTION
MAX MCR  A/B is an unfilled medium working time, low viscosity potting compound resin system for embedding or encapsulating printed circuit boards (PCB), relays, coils, and other electronic components and circuitry.
MAX MCR A/B is low in viscosity and it is room temperature cured (50°F to 90°F). It is mixed 2:1 by weight or by volume and provides a 30 minute working time (200-gram mass).
The mixed consistency is similar to that of mineral oil and it is poured in place, injected or it is adaptable for mix meter dispensing equipment.
MAX MCR is completely non-electrically conductive that prevents direct physical contact with the circuitry. It cures to a hard and tough compound that is suitable potting small to medium parts up to 6 ounces (180 grams) in mass without excessive exothermic heat generation. It provides a 30-minute working time when mixed up to 200-gram mass.
MAX MCR A/B bonds to PVC, PP, ABS, plastisol, aluminum, steel, copper, brass and other materials typically used in electrical assembly and printed circuits boards.
Upon cure, MAX MCR A/B is hard and waterproof suitable for continuous water immersion and exposure to harsh environments that protects electrical connections from c.
Its opaque black color permanently masks proprietary
circuit
and electronic components from.

THIS KIT INCLUDES A SET OF YORKER CAPS FOR CONTROLLED DISPENSING.
Use these Yorker caps to dispense the material with ease and minimize over pouring and reduce spills. C
ut the tapered tip to meter the orifice of the tip for accurate dispensing.  When done, just replace the tip cap and it will exclude ambient moisture and air and keep the resin system viable for years.
We do not recommend using dispensing pumps. The curing agent or part B of any epoxy resin system is sensitive to moisture and carbon dioxide, which will react with the curing agent and form carbamate crystals (salt-like crystals that form on the tip of the pump) and reduce reactivity.
Unless the kit is used continuously and within a short period of time, using dispensing pumps will cause more problems than ease-of-use.

EPOXY RESIN MIXING AND USAGE APPLICATIONS
The use of a weighing scale is highly recommended for proportioning the 2:1 mix ratio. Using volumetric measuring is fine, however, weighing the resin and curing agent yields better-cured mechanical properties, batch repeatability, and less waste from mixing over-sized batch. Use this digital scale to precisely weigh the resin and curing agent and ensure full polymerization of the resin and curing agent and prevent leaching.
Purchase this scale with any of product offering and the shipping cost of the scale is free.
Please request a total before paying for combined shipping savings.

EVERYTHING YOU NEED TO MEASURE, MIX, DISPENSE OR APPLY
Proportioning the correct amount is equally as important to attain the intended cured properties of the resin system.
T
he container in which the epoxy and curing agent is mixed is an important consideration when mixing an epoxy resin system.
The container must withstand the tenacity of the chemical and must be free of contamination.
Most epoxy curing agent has a degree of corrosivity, as a general practice, protective gloves should be worn when handling chemicals of the same nature.
