UST Awning/Sign Sealant Tape


Installation Guidelines

Available in many sizes.
If this tape size does not return the results you desire in your specific application, ask for other size options.

Tape must be kept compressed to a sealing density level appropriate to the application and desired level of sealing (see compression chart).

1. Storage and Surface Preparation
Tape should be stored in a warm dry interior location. Ideal application temperature is approx. 75°F (24°C). Expansion will be faster at higher temperatures and slower at lower temperatures.

Tip: For faster expansion in cold conditions keep the material warm before use and, if desired, apply heat from a hair dryer to installed material to accelerate expansion. Joint faces should be dry and cleaned of dirt, oils, grease, etc. There should exist sufficient depth to receive full width of the sealant.

IMPORTANT: Reels must be stored FLAT and kept compact. Should material expand in package it can still be used. Unroll material, allow it to expand, then recompress it between surfaces to be sealed.

2. Opening Reels
Only open materials that will be immediately used. Remove shrink wrap. Cut through outer liner at colored marking tape to start.

3. Square Off Ends
Start and finish ends must be cut square. For easier cutting spray knife or scissors with mist of water.

4. Peel Off Liner
Remove release liner to expose adhesive face of tape.

5. Adhere/Align to Surfaces
Press adhesive face to one surface. Align other surface with tape. Secure surfaces together.
Tip: If needed cut and fit small filler pieces of tape to fill panel corrugation or voids.

6. Join Lengths with Miters
To form a continuous strip overlap tapes and miter with a moist knife at 45° angle. Pinch mitered faces together.

Product Innovation:
EMSEAL UST Awning/Sign Sealant Tape features a breakthrough in sealant technology. The innovation comes in the composition of the acrylic adhesive infused into the cellular foam base material.
This new proprietary chemistry incorporates a hydrophobic component never before available in a sealant formulation. The result is a material that features sealing performance significantly greater than any acrylic-impregnated predecessor. In addition, it is odorless, clean handling, UV stable, non-staining, and highly versatile.
 
Product Description:
EMSEAL UST Awning/Sign Sealant Tape is a preformed expanding tape seal. UST is made of a resilient cellular foam infused with a hydrophobic, modified- acrylic, liquid adhesive sealant which is then compressed to a sealing density level appropriate to the application. The result is a hybrid sealant that features the best characteristics of foam and liquid sealants while eliminating their respective weaknesses.

UST compresses uniformly without overspill to provide a lasting seal. UST is available in a wide variety of configurations.

Users determine the size of UST suited to their specific application and performance needs.

Typically, higher compression levels are required for watertightness in standing water or water run-off applications; lower compression can be used, for example, in drier applications (see compression chart below).

UST replaces and outperforms liquid and butyl-tape sealants as well as closedcell and unimpregnated open-cell foam closures.

EMSEAL UST is packaged precompressed in rolls. The material contains a pressure sensitive mounting-adhesive on one face to facilitate installation.

Product Uses:
UST sealant tape is used to seal out dust, air, wind-driven snow, and moisture at the awning to building-face junction.

UST is suitable for use against metal, plastic, wood, concrete, and other materials common in building structures. It is also effective in preventing the leakage of light between installation bars and building surfaces.

Product Features:

• Clean handling, non-staining, odorless, UV-stable
• Will not extrude from between joints like caulk or butyl tapes
• Conforms to contours and fills gaps
• Maintains a seal during thermal expansion and contraction of building components
• Provides a long-term seal
• UV-stable
• Excellent compressibility and recovery (minimal compression set)
• No shrinkage or failure due to cell breakage as in closed-cell types
• Maintenance free – doesn't need recaulking
 
Compression Levels

Higher levels of compression offer greater protection

* Watertight up to 5 PSF per ASTM E-331 modified to run 24 hours instead of standard 15 minutes. This equates to a 1-inch standing head of water for 24 hours without leakage.

Tape Selection Guide
Use the Compression Levels chart to select a size that ensures the proper degree of sealing to suit the application. The following is a general guide to tape selection:
 
Stucco, block, brick
Split block
Commercial grade corrugated metal
UST-15-15-08
UST-35-20-04
UST-30-20-04

Limitations

• UST will not adhere to components that are dirty or dust covered or to surfaces coated with oils or other release agents.
• UST will expand to follow and fill irregular substrates within reason. Sharp corners and acute angles may need to be filled with additional filler pieces of UST in order to ensure a proper seal.
• Substrate must be capable of resisting, without deflection, approximately 1.5 to 2.5 lb/in2 (10 to 17 kPa) back pressure from the UST.
