What is Strength?
Tensile strength simply measures the degree to which a substance can be stretched before it ultimately breaks. Tensile strength is one of the most critical categories for roof coatings, since it determines how durable the coating will be. Roofs tend to expand and contract in response to the outside temperature, so the coating needs to be strong enough to respond to those changes without being undermined. When you’re searching for a durable roof coating, it’s important not to neglect the importance of tensile strength.
