RVS–Recreational Vehicle Sealant Tape

Product Innovation:
EMSEAL RVS RV 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/hydrophilic 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 RVS Sealant Tape is a preformed expanding tape seal. RVS 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. RVS compresses uniformly without overspill to provide a lasting seal.

Available in a wide variety of configurations, recreational vehicle manufacturers determine the size of RVS suited to their specific applications and performance needs.

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

Uses and Applications:
RVS is an effective seal against water, vapor, air, sound, dust, allergens and vibration.
RVS is suitable for use on painted or unpainted metal, plastic, glass, wood, or other surfaces, as well as between dissimilar materials.

For applications requiring high temperature stability.

Ideal as a gasket tightly squeezed between joint faces that are mechanically fastened together such as in window and trim applications.

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

As a secondary seal behind liquid sealant.

RVS precompressed, self-expanding foam sealant fills corrugations and seals window, door, vent, and hatch penetrations.

RVS precompressed sealant tape conforms to corrugated coach sides. It only compresses into itself. The sides of the tape stay flat even when installed under compression from fasteners.

A failed or non-functioning perimeter sealant can cause severe damage. Low cost butyl sealants extrude out leaving gaps in corrugated coach panels.

Damage from failed sealants is far more costly to repair than that of a higher functioning sealant.

Features

• Does not dry out.
• Does not extrude out.
• Tolerant of joint face irregularities.
• Ideal as secondary seal to wet sealants.
• Handles jarring, vibration, thermal, and torsional movements of body and chassis.
• Odorless, clean handling and non-staining
• Exposed face remains virtually flat regardless of variation and changes in joint width and compression.
• User friendly—no masking, mixing, priming, tooling, curing, clean-up or special tools required.

Sealing Levels & Compression

The following indicates levels of sealing at respective installed compression levels:

The Choice: AST or MST?

AST Hi-Acrylic is by volume the most widely used. Black in color as the result of it’s advanced acrylic-modified asphaltic impregnation, AST affords economy without sacrificing performance.

MST features the latest in acrylic chemistry and is grey in color. Choice of MST over AST is really a preference of the user for color and chemistry.

Installation

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 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
Overlap one piece of tape with another. Cut through both pieces at a 45-degree angle with a long-bladed knife. Reposition mitered faces over each other and pinch them firmly together to make a join.

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

Limitations

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