MAX MCR 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.
It 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 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.

NOTE THE DIMENSIONAL STABILITY AND LOWERED DIMENSIONAL SHRINKAGE BY THE ADDITION OF THE CALCIUM CARBONATE.
BOTH SYRINGES WERE FILLED WITH MAX MCR.
THE BOTTOM SYRINGE WAS FILLED WITH TO A SOLUTION OF 25% CALCIUM CARBONATE AND 75% MIXED MAX MCR A/B.
BOTH SPECIMENS WERE VACUUM DEGASSED TO REMOVE ANY MIX BUBBLES OR MICRO AIR ENTRAPMENT PRIOR TO FILLING.
THE TOP SYRINGE WAS LEFT UNMODIFIED AND UNFILLED.
UPON CURE THE BOTTOM SYRINGE DEMONSTRATED LESS SHRINKAGE AS ILLUSTRATED BY THE PHOTOGRAPH
NOTE HOW THE UNMODIFIED FORMULATION (TOP) DEMOLDED FROM THE SYRINGE HOUSING, THIS INDICATES HIGHER VOLUMETRIC SHRINKAGE DURING POLYMERIZATION. A 0.3 T0 0.5 DIMENSIONAL SHRINKAGE IS TYPICAL IN ANY POLYMER CONVERTION FROM A LIQUID POLYMER TO A SOLID PLASTIC. SINCE LESS VOLUME OF RESIN IS USED ON THE BOTTOM SYRINGE, A LOWER AMOUNT OF SHRINKAGE IS ALSO OBSERVED. THE MODIFICATION ALSO IMPROVED HARDNESS OF THE RESIN BY 5 POINTS SHORE D HARDNESS SCALE,

Composite Fabricating Basics TYPES OF FABRIC WEAVE STYLE AND SURFACE FINISHINGFOR RESIN TYPE COMPATIBILITY
Satin Weave Style For Contoured Parts FabricatingThese styles of fabrics are one of the easiest fabrics to use and it is ideal for laying up cowls, fuselages, ducts and other contoured surfaces
with minimal distortions. The fabric is more pliable and can comply with complex contours and spherical shapes. Because of its tight weave style,
satin weaves are typically used as the surface ply for heavier and courser weaves. This technique helps reduce fabric print through and requires
less gel coat to create a smoother surface.
A POLYMER RESIN'S PHYSICAL PROPERTY SUCH AS ITS VISCOSITY AND CURE RATE ARE HIGHLY AFFECTED AND INFLUENCED BY TEMPERATURE.DURING THE COLDER SEASONS THE RESIN AND CURING AGENT SHOULD BE WARMED TO AT LEAST 75 F to 80 F (21 C to 27 C) PRIOR TO USE TO REDUCE ITS VISCOSITY TO REDUCE AIR BUBBLE ENTRAPMENT AND MAINTAIN ITS WORKING TIME AND PROPER CURE. THE HIGH PURITY EPOXY COMPONENT AND THE ABSENCE OF ANY ACCELERATORS IN ITS FORMULATION ARE SOME OF THE MANY KEY FACTORSTHAT CONTROLS ITS COLOR STABILITY. THE COLD TEMPERATURE WILL ALSO MAKE THE RESIN MUCH THICKER THAN THE STATED VISCOSITY AND WORKING TIME VALUES STATEDON THE PHYSICAL TABLES CHART. THIS WILL REDUCE THE POLYMER'S REACTION RATE AND EXTEND ITS CURE TIME.THIS CAN RECTIFIED BY USING THE MIXED RESIN IN A WARM ROOM AT TEMPERATURES NO LOWER THAN 70 F .
* PLACE THE BOTH CONTAINERS IN A HOT BOX OR A WARM ROOM AND ELEVATE THE AMBIENT CURE TEMPERATURE AT LEAST 80 TO 90 F.
* IF THE RESIN HAS SOLIDIFIED OR CRYSTALLIZED (AN INDICATION OF THE RESIN S HIGH GRADE PURITY), IT CAN EASILY BE REVERTED BACK TO A LOW VISCOSITY LIQUID EXPOSE BOTH RESIN AND CURING AGENT UNDER SOLAR, RADIANT HEAT OR HOT WATER (150 F TO 180 F) IMMERSION FOR SEVERAL AND ALLOW TO COOLBELOW 90 F BEFORE ADDITION OF THE CURING AGENT.
* UPON CURE TO THE TOUCH, A SHORT HEAT POST CURE USING INFRARED LAMPS (120 F TO 150 F FOR 2 HOURS) WILL ACCELERATE AND INSURE FULL CURE

Over saturation or starving the fiberglass or any composite fabric will yield poor mechanical performance.
COMPUTING FABRIC TO RESIN RATIO BY WEIGHT
AN ACCURATE DIGITAL SCALE IS HIGHLY RECOMENDED RATHER THAN GOING BY FABRIC
DATA AND VOLUMETRIC RESIN MEASURING AND PROPORTIONING.
WEIGH ALL FABRICS TO BE USED TO DETERMINE FABRIC TO RESIN RATIO
A good rule of thumb is to maintain a minimum of 30 to 35% resin content by weight, this is the optimum ratio used in high performance
prepreg (or pre-impregnated fabrics) typically used in aerospace and high performance structural application.

Apply the mixed resin unto the surface and
then lay the fabric and allow the resin to saturate the fabric.
Given enough time and the proper selection of the fabric's surface treatment (fabric to resin compatibility), a dry fabric will seek a state equilibrium and distribute
the applied resin and naturally release air bubbles entrapped within the laminant.

Some darkening or yellowing of the epoxy resin may occur if over exposed to high temperature (>250 F). This color darkening is mostly caused by thermal oxidation process in which FREE RADICAL compounds are created via thermal energy (heat).
The affinity of an amine compound (curing agent) to moisture and
carbon dioxide creates a carbonate compound and forms what is called amine blush.
