  • Does Tremco have a “100% Silicone Glazing Sealant”?
    The term 100% silicone sealant indicates that the sealant is a RTV (room temperature vulcanized) silicone sealant and is not a hybrid such as a MS (polyether silyated) or SPUR (silyated polyurethane) sealant. Tremco’s silicone sealants are 100% silicone or RTV silicone sealants.
  • What type of glazing materials does Tremco provide to the glazing market?
    Tremco manufactures and sells a variety of silicone sealants such as Spectrem 1, Spectrem 2, Proglaze SSG, Proglaze II. In addition, Tremco offers a wide variety of standard and custom extruded rubber products (EPDM, neoprene, silicone and thermoplastics), shimmed and unshimmed butyl tapes, and foamed urethane tapes.
  • What are the requirements for a structural silicone sealant?
    A structural silicone sealant must, as a minimum, meet ASTM C1184 in order to qualify as a tensile or weatherseal sealant in Structural Glazing Applications. Spectrem 2, Proglaze SSG and Proglaze II meet the minimum performance criteria as listed in this specification.
