PRODUCT DESCRIPTION
MAX MCR BLACK 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 or electrical circuitry.
MAX MCR A/B is 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 non electrically conductive offers a very high gloss finish blemish free surface.
It cures to a hard but tough compound that is suitable for small to medium parts (up to 200 grams/6 fluid ounces).
The 2 to 1 mix ratio offers ease of use and easily poured in place or can be adapted for mix meter equipment.
MAX MCR A/B bonds to PVC, PP, ABS, aluminum, steel, copper, brass and other materials typically used in electrical circuits.
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.

EPOXY RESIN MIXING AND USAGE APPLICATIONS
RESIN CRYSTALLIZATION FROM PROLONGED STORAGE OR COLD WEATHER EXPOSURE
The resin component or PART A may crystallize due to cold temperature exposure, especially after prolonged storage.
Before using inspect the resin component for any solidified crystals which will as solid solid mass or grainy solids that collects at bottom of the PART A bottle.
View the following video for heat processing the bottle before use.
Do Not Use Unless Processed To Revert Any Crystallized Resin Back To A Liquid State And Avoid Poor Cured Results.
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.

Please View The Following Video For The Proper Mixing Of Epoxy Resins.
It Demonstrates The Proper Technique Of Mixing Any Type Of Epoxy Resin.
The Proper Cure And Final Performance Of Any Epoxy Resin System Is Highly Dependent On The Quality And Thoroughness Of The Mix.
The Resin And Curing Agent Must Be Mixed To Homogeneous Consistency.
EVIDENCE OF POOR MIXING
The proper cure and final performance of an epoxy resin system are highly dependent on the quality and thoroughness of the mixing quality.
The resin and curing agent must be mixed to homogeneous consistency to achieve proper cure and tack-free results.

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.
The 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. MIXING KIT CONTENTS 1 Each Digital Scale -Durable, Accurate Up To 2000.0 Grams
