Master Bond formulations are available in a wide range of hardnesses. Compounds are designed to optimize performance and productivity.
Master Bond hardness testing is based on ASTM D 2240. Commonly used hardness scales are A and D. Shore A is used for softer materials, whereas shore D is used for harder materials. In order to measure the hardness, the sample is first placed on a flat surface, and the indenter is pressed into the sample. This test is usually repeated a few times at different locations on the sample, and the average reading is then used as the hardness.
The chart below offers an overview of the hardness range (Shore A and Shore D) available in our vast product line:
