D734 Room Temp Debulking / Edge Dam

Printable Data: TDS Sheet

SKU: D734. Category: .

This product is a 100% solid black Butyl tape. The product has applications as a composite DeBulking Vacuum Bag Tape as well as for Transparency formation. It is also recommended for tape glazing of windows for a variety of applications. This product provides resistance to high load squeeze-out.

FDA STATUS: A letter is available upon request.

Physical properties are tentative pending production history.

LIMITATIONS

When channel glazing is over 100 united inches, or when there is excessive wind load, spacing shims are required to be placed on the perimeter of the fixed stop on 18″ centers to compensate for excessive forces. These spacing shims transfer wind loads safely from glass to sash and prevent glass-to-metal contact. Installation must provide adequate tape compression.

COMPOSITION AND MATERIALS

This product is made from a specially formulated compound of 100% solids in a base of cross-linked butyl rubber. Due to the balanced properties of adhesion, cohesion, and elasticity, it does not harden or lose flexibility, adhesion, or elongation after prolonged exposure to high temperatures and ultra-violet light.

Special order versions of this product incorporate a continuous spacer rod within the tape to transfer wind loads from glass to sash and eliminate the need for spacing shims. The continuous spacer is centered throughout each roll. The rod is slightly smaller than tape thickness, i.e., 125″ tape size/.100″ rod size.
