I received my material, but one of my containers was only ½ full. Is this a mistake?

Materials are packed by weight – don’t judge by appearances.

Our rubbers, plastics and foams are dispensed into the above containers by weight. Depending on the density of the material that you buy, the volume of the material in theses containers may be less or more. For example, a gallon unit of Vytaflex 20 urethane mold rubber contains 16 lbs. of liquid in both sides (A + B) and is 7/8 full by volume. A gallon unit of Brush-On 40 contains 18 lbs. of material – liquid in the Part A side and a heavy paste in the Part B side. Due to the density of the paste material, the Part B will only fill a gallon bucket ½ full volumetrically.

Don’t estimate the amount of material needed for your application by volume. Correlating the cubic inch per pound yield of the material with the cubic inches of your original (and possibly your mold box) is a more accurate determination for your material requirement.



The FAQ list is offered as a guideline and offers possible solutions to problems encountered during mold making and casting. No warranty is implied and it is up to the end user to determine suitability for any specific application. Always refer to the provided Technical Bulletins (TB) & Material Safety Data Sheets (MSDS) before using any material. A small scale test is suggested to determine suitability of any recommendation before trying on a larger scale for any application.
