CRL Tremco® POLYshim™ II Tape is a 100 percent solids, highly adhesive and elastic, cross linked preformed butyl tape. Use it in compression glazing systems wherever the design calls for high performance glazing of curtain wall, unitized curtain walls, punched and ribbon window systems, and sloped glazing applications.

The continuous rubber shim works to prevent sealant squeeze-out because it is resilient to pressure exerted by building and glass expansion or contraction. It also helps prevent glass breakage by eliminating pressure points created by improper shimming. The continuous shim eliminates the need for preshimming the lite before installing the tape. Tremco® Pre-Shimmed tape has good adhesion, heat resistance, sealant compatibility, and resistance to weathering. It can be used in conjunction with many glazing systems.

Typical Physical Properties
Base Polymer: cross linked butyl rubber (polyisobutylene); Solids Content: 100% by weight. Hardness: 57 durometer Shore "00". Temperature Range: Application 20°F (-7°C) to 120°F (49°C); Service -65°F (-54°C) to 200°F (93°C). Weathering: Unaffected by Ultraviolet through glass. Remains flexible at low temperatures.

Applicable Standards
POLYshim™ II Tape meets the requirements of AAMA 800-92 Specifications 804.3, 806.3, and 807.3.

Limitations
Not for use in joints subjected to continuous water immersion or temperatures exceeding 200°F (93°C). Do not compression glaze glass with POLYshim™ II Tape having less than an 1/8" (3 mm) shim.
