Manufacturers must designate sealants using this four-part system to specify exactly where and how a product should be used: : Indicates the number of components.

Durable enough for pedestrian or vehicular traffic areas like plazas or walkways. These sealants are designed to provide a flexible

Elastomeric joint sealants are widely used in construction to seal joints and gaps in various building components, such as windows, doors, and concrete slabs. These sealants are designed to provide a flexible and watertight barrier against environmental elements, while also accommodating movement and stress caused by thermal expansion and contraction. The American Society for Testing and Materials (ASTM) has developed a standard specification for elastomeric joint sealants, known as ASTM C920. This paper provides a summary of the key requirements and testing methods outlined in the ASTM C920 standard. such as windows
