DESCRIPCIÓN
Preformed butyl tapes have unique properties which allow their use in a diverse spectrum of applications. When choosing a butyl tape as a sealant for a given application, one should understand the properties of the tape and its limitations:
 
LIMITATIONS:
 
• Tremco tape sealants adhere to surfaces by means of their inherent tack. For proper performance, they must be com- pressed between surfaces. Preformed tape sealants should not be used as mounting tapes.
 
• Tremco butyl tape sealants are considered compatible and acceptable for glazing acrylic and polycarbonate sheet. However, the severe thermal movement that is characteristic of such applications can cause permanent deformation and squeeze-out of the tape. Glazing plastic sheet with tape sealants should be restricted to small lites, with a maximum dimension of approximately 36 inches (914mm).
 
• In solar collector applications, butyl tape sealants are subject to out-gassing at relatively low stagnation temperatures. The resulting condensation can reduce the efficiency of the collectors. The use of tapes in solar collectors should be restricted to low-performance collector systems.
Tremco offers two glazing tapes to the commercial construction industry. One of the most important steps in any tape glazed project is to insure that the correct tape has been selected for the application.
