  • Publication number: 20240052639
    Abstract: A roof system comprising a substrate and thermoplastic membrane adhered to the substrate, where the thermoplastic membrane is characterized, prior to being adhered to the substrate, by a stiffness represented by a flexural modulus of less than 90 MPa, or by a Taber stiffness of less than 15, or by a Shore D hardness of less than 40, or by a combination of a flexural modulus of less than 90 MPa, a Taber stiffness of less than 15, and a Shore D hardness of less than 40.

  • Patent number: 10221290
    Abstract: A method for making a cured rubber sheet, the method comprising providing an uncured rubber sheet, where the uncured rubber sheet includes opposing planar surfaces, applying a curable coating composition to one planar surface of the sheet to form a layer of curable coating composition, subjecting the curable coating composition to curing conditions that cure the coating composition and thereby form a cured coating layer on the uncured rubber sheet, rolling the uncured rubber sheet having a cured coating layer onto itself to form a roll, and subjecting the roll to curing conditions that cure the uncured rubber sheet and thereby forms a roll of cured rubber sheet.
