UST Literature Sheet

Installation Sheet

Innovative Technology:

This preformed expanding tape seal features a major breakthrough in sealant technology. EMSEAL UST Sealant Tape is composed of a cellular-modified acrylic adhesive  material never before available in a sealant tape infused into a cellular foam base. This creates sealing performance significantly greater than any earlier impregnated product.

In addition, it is odorless, clean handling, UV stable, non-staining, and highly versatile.
 

Product Features:
• Clean handling, non-staining, odorless, UV-stable
• Resistant to bugs and vermin
• 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
• Does not dry out
• Compatible with and adheres to most wet sealants
• No shrinkage or blow-out due to closed-cell breakage
• User friendly – no masking, mixing, priming, tooling, curing or clean-up required
 


UST tape compresses without overspill and expands to fill voids.
Available in a wide variety of configurations, users determine the size of MST suited to their specific applications and performance needs.

A Wide Range of Uses:
UST sealant tape can be used to seal out moisture, dust, air, wind-driven snow, between metal surfaces, concrete, plastic, wood and other substrates. UST is ideal as a filler in expansion/compression joints subject to movement from thermal expansion and contraction, and as a gasket in mechanically fastened, non-moving applications.

Water, vapor, air, sound and dust seal Applications requiring high temperature stability.

Ideal as a gasket tightly squeezed between joint faces that are mechanically fastened together such as lap seams.

Filling preformed openings between components and where joint opening size varies due to seasonal temperature changes.

In applications where damping vibration and noise is as important as weather sealing.

Sealing between the UST and the substrates is a result of the foam's cell structure, the impregnation, and the appropriate degree of compression. EMSEAL UST is packaged precompressed in rolls. The material contains a pressure sensitive mounting-adhesive on one face to facilitate installation.
 

Product Description:
UST is made of 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 featuring the best characteristics of foam and liquid sealants while eliminating their weaknesses. UST replaces and outperforms liquid and butyl tape sealants, closed-cell and unimpregnated open-cell foam closures.

UST is available in a wide variety of configurations. Simply determine the size of UST suited to the specific application and performance needs. Typically, higher compression levels are required for watertightness in standing water or water run-off; lower compression can be used for temperature and sound barriers or other fill-in applications. (see compression chart).
 


Installation Guidelines

1. Storage and Surface Preparation
Tape should be stored in a warm dry interior location. Ideal application temperature is approx. 75F (24C). 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 in front of colored marking tape and pull back release liner to expose mounting adhesive.

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 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. Joining Lengths

Work in one direction towards the previously installed length or end of joint. Do not stretch material.
Leave the end to be joined to the previous length sticking proud of the joint. Push the joining faces together. Push hard on the foam length to compress joins firmly together. Ensure there are no voids at joins.
Once the full length is installed, push the protruding
join into the joint.

Available in many sizes.

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






 


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.

Standard and Custom Sizes
EMSEAL products are available in numerous standard and custom configurations and are available for shipment internationally. The product range is continually being developed. EMSEAL reserves the right to modify or withdraw any product without prior notice.
