ASTM C570-00 PDF Download

ASTM C570-00 is a standard specification that outlines the properties of a one-component oil- or resin-base caulking compound for use in building construction. This specification distinguishes between the drying and non-drying types of caulking compounds, with a focus on the former. The drying type refers to compounds that oxidize and form a surface skin upon application, while the non-drying type is designed for use on concealed surfaces.

The purpose of this standard is to provide guidelines for the composition and performance of oil- and resin-base caulking compounds used in construction applications. It ensures that the compounds meet certain minimum requirements, including properties related to adhesion, workability, curing time, and resistance to weathering and aging. By specifying the necessary properties, this standard aims to provide a consistent and reliable caulking compound that can effectively seal and fill joints and gaps in building structures.
