The specific gravity of a product can be found on the material safety sheet how do you know if a product will flow in water?

You can determine if a product will float or sink in water based on its specific gravity compared to that of water. If a product's specific gravity is less than 1, it will float in water. If it is greater than 1, it will sink. You can find this information on the material safety data sheet (MSDS) for the product.
