| Stronger, better sealed windows and doors As residential and commercial construction reaches record levels in many parts of the world, window and door manufacturers of all sizes are turning to new glazing technology to keep pace with demand. Chemists at Dow Corning Corporation have developed a sealant that allows fabricators to manufacture stronger and better-sealed silicone-glazed windows and doors. In addition to improving the seal and strength of the windows, the technology reduces the time and cost associated with window and door manufacturing by as much as 33 percent. Glazing in the window and door manufacturing process is usually accomplished with adhesive tape or liquid sealants. Each has drawbacks: Glazing tape requires no expensive equipment and allows the sash to be processed immediately, but consistency and quality of application can be an issue and rework is time-consuming. Liquid sealants provide superior performance but they often squeeze out when glass is pressed into the frame, and requiring an additional clean-up step. More importantly, the windows must be set aside after glazing to allow the bedding material to cure, taking time and space. Dow Corning(R) InstantGlaze Window Assembly Sealant combines the best features of both techniques. InstantGlaze provides as much adhesive strength as tape, so windows can be finished and shipped. The window can be glazed up to 15 minutes after the InstantGlaze has been applied. High viscosity at room temperature virtually eliminates squeeze-out. The sealant then cures to its full strength. write your comments about the article :: © 2005 Construction News :: home page |
