Based on polyurethane reactive hot melt technology, this specialty adhesive has passed AAMA(r) verification and has been subjected to an additional battery of tests including UV exposure, accelerated weathering, performance under wide temperatures and humidity, and air/water/structural testing. Unlike other wet glazing systems such as silicones and acrylics, PURFECT GLAZE adhesive results in handling strength within two minutes of applying the bead to the sash. The high green strength permits most manufacturers to package their windows within minutes and ship within the hour from bedding the glass, without causing quality complaints.
PURFECT GLAZE adhesives PG 38A and PG 69A develop strength (more than 200 psi for PG 69A) within 30 minutes of application. Under most conditions, users will notice the following:
- lower labor costs;
- increased productivity from existing assets;
- fewer field complaints from warped, bowed or leaky windows;
- less work in progress;
- less inventory; and
- increased ability to meet short-lead-time orders.
