Calcium Carbonate Resin Filler, Improve Mechanical, Dimensional, Stabilty Heat

Description: Calcium Carbonate Powder Marble Dust 325 MESH CaC03 -99% Powder 3 Pounds Net Weight One Quart Net Volume HIGH-EFFICIENCY EPOXY RESIN FILLER Marble Dust or Calcium Carbonate is a mined mineral that has undergone metamorphosis under high pressure and high temperatures treatment. This process results in re-crystallization with the separation out of impurities in the form of characteristic veins known as "marbling". As a metamorphic rock, marble has a dense crystalline structure of high chemical purity and high whiteness.

Calcium carbonate is a dense when blending with an epoxy resin.The density of the filler and the amounts added may vary and affect mix ratio proportioning by volume and cause curing problems. Using weight measurements with a scale will ensure proper mix ratio proportioning (for example, 1:1 and 2:1 mix ratios) THE USE OF A WEIGHING SCALE IS HIGHLY RECOMMENDED TO ENSURE PROPER CUREPurchase This Scale With Any Of Our eBay Offering And Shipping Cost For The Scale Is Free https://www.ebay.com/itm/222630300203Resin System Used: MAX CLR A/B Available Kit Sizes24 OUNCE KIThttps://www.ebay.com/itm/22262396319448 OUNCE KIThttps://www.ebay.com/itm/31194732010196 OUNCE KIThttps://www.ebay.com/itm/22262532906896 OUNCE KIThttps://www.ebay.com/itm/2226253382301.5 GALLON KIThttps://www.ebay.com/itm/222626972426PROCEDURE The amount of calcium carbonate will vary upon the intended application. High filler loading >50% is possible but will affect the viscosity and cured mechanical properties. A 'ladder study should be done to determine the optimum filler loading. For general use as a filler for an epoxy resin system, use 30% by weight as a starting point addition has shown a dramatic and balanced improvement in both physical and mechanical properties. The addition of the calcium carbonate was incorporated in the resin component only. Since the resin will not cure without the curing agent, adding the calcium carbonate to the resin component, air bubbles can be allowed to outgas from the mixture by allowing it to stand for an extended period. Gently stir in the calcium carbonate to reduce air entrapment. It is highly recommended that it be added to the resin component or 'PART A' only since the curing agent or PART B is hygroscopic and will absorb and react with moisture that is imbued in the calcium carbonate. The resin component (PART A) is very hydrophilic which will displace the entrapped water molecules from the filler. Water is 10% less dense than epoxy so the displaced water will float to the surface and evaporate, creating an anhydrous solution. In the pictures below 50% by weight of calcium carbonate was added to the Resin or PART A component (50% by weight).The sample on the left was allowed to rest and degas for 24 hours at room temperature and remixed to redistribute the calcium carbonate. Gentle stirring will pop the surfaced air bubbles and also re-disperse the calcium carbonate uniformly.Faster degassing performance can be achieved by heating the mixture our using a vacuum chamber.

Allow the mixed resin to de-gas at room temperature or soak the container in a warm water bath and then allow to cool before adding the curing agent. Add Curing Agent and mix as described above. Note that the ratio between the base resin and base curing agent is kept at the original 2:1 mix ratio. Part BMAX CLR Curing Agent50 grams NOTE THE DIMENSIONAL STABILITY AND LOWERED DIMENSIONAL SHRINKAGE BY THE ADDITION OF THE CALCIUM CARBONATE.Both syringes were filled with MAX MCR A/B as the base resin.The top syringe was left unmodified and the bottom syringe contains 25% calcium carbonate and 75% mixed resin. Upon cure the bottom syringe demonstrated less shrinkage as illustrated by the photograph, note how the unmodified formulation (top) demolded from the syringe body. This indicates higher volumetric shrinkage during polymerization. The Calcium Carbonate filled sample also demonstrates improved hardness of the resin by 5 points Shore D Hardness ScaleCalcium Carbonate Filled Casting Resin For Thermoform Tooling Mold Calcium Carbonate With Color Addition DemonstrationMAX ACR With Calcium Carbonate Addition For Color Opacity And Buoyancy MAX ACR A/B: https://www.ebay.com/itm/223829993471 Use this filler to improve dimensional stability, thermal conductivity, and electrical insulating properties of an epoxy resin. It is also used to increase color opacity when added to of any of our MAX EPOXY RESIN SYSTEM with MAX EPOXY COLORANTS for color pigmentation.MAX COLOR PIGMENT CONCENTRATESThese are color concentrates only and must be dispersed an epoxy resin or PART A component.
