Temperature will affect the viscosity of most materials, these estimated numbers are based on measurements at 73☏ / 23☌Ĭlick here to download a pdf of the Viscosity Scale Reference Guide. Please check Technical Bulletins for specific mixed viscosity of products. These are general averages and NOT specifics, not all products fit neatly in this chart. If the mixed viscosity of the casting resin you are using is higher than 7,500 cps, you may want to consider vacuum degassing or pressure casting the resin.ĮVERYDAY CONSUMABLE GOODS IN RELATION TO GENERAL PRODUCT VISCOSITY IN CENTIPOISE (CPS) Water 70☏ / 21☌ This is especially true if the resin has high viscosity and short pot life. Air bubbles may then be reflected in a finished casting. What does viscosity mean to you when selecting a casting resin? If you are using a casting resin with a high viscosity, there is a chance the casting will entrap air. Oils of lower or higher viscosities (than the optimum viscosity) will typically increase the oils stabilized temperature due to either churning losses (too. You can think of water (low viscosity) and honey (high viscosity). Thin, low viscosity oils flow easier to protect engine parts at. If the mixed viscosity of the mold rubber you are using is higher than 15,000 cps, you may want to consider vacuum degassing the liquid mold rubber. Viscosity is often referred to as the thickness of a fluid. This is important, as engine oils naturally thicken as they cool and thin as they are heated. What does viscosity mean to you when selecting a mold rubber? If you are using a mold rubber with a high viscosity, there is a chance the rubber will cure with air bubbles that may then be reflected in a finished casting. These high quality dental diamond burs are sold in different sized packs (1, 5, or 50) for your convenience. Temperature will affect the viscosity of most materials. The higher the viscosity of a liquid, the thicker it is and the greater the resistance to flow. In layman’s terms, viscosity defines a fluid’s resistance to flow.
