Why Shelter-Rite® Brite™ with Kynar®
The Shelter-Rite Difference
Shelter-Rite® fabrics for the architectural structure market are manufactured by Seaman Corporation, a world leader in the innovation and manufacturing of high-performance coated fabrics since 1949. A vertically integrated company, Seaman Corporation develops proprietary formulations, knits, weaves, coats and inspects all of its materials in two U.S.-based plants. Since the company patented and introduced the first Portomod framed structure to the market in the mid-1960's, Shelter-Rite architectural fabrics have been preferred by architects, designers and fabricators for commercial and military projects throughout the world.
Shelter-Rite fabrics are engineered to ceate a variety of unique structures:
- Air-Supported
- Pre-Engineered Frame
- Custom Engineered Tension
- Rental Tents
45 Years of Proven Performance
Kynar was introduced in 1965 as a paint additive for standing-seam metal roofs and many other applications. Standing seam metal roofs with the Kynar finish have earned a reputation of maintaining their "like new" appearance for well over 20 years. Now, this technology is available on a coated fabric, providing far superior performance compared to standard PVDF and Acrylic coatings, and at least, comparable performance compared to PVF films:
- Retention of color
- Retention of gloss
- Stain resistance
- Dirt pick-up
- Mildew resistance
- Chemical resistance
- Water repellant
- Film erosion
- Chalking
- Flexibility
- Cleanability
- Transmittance
Advanced Formula
Twice the Fluorine Content for Superior Performance vs. PVF
Kynar's superior protection is due to simple chemistry. Scientists incorporate a high level of fluorine into its chemical structure; actually, twice the content vs. PVF. Given fluorine provides one of the strongest chemical bonds known to man, the Kynar polymer is highly resistant to breaking down.
Proven Technology - Superior Flexibility

Thicker Top Finish
Kynar vs. Standard PVDF, Acrylic and PVF (white)
Conclusion: In addition to being a superior formula, ounce per ounce, Kynar is also thicker; together providing extended life.
Superior Retention of Gloss

Conclusion: The Shelter-Rite Brite with Kynar maintains its gloss during the test period, while the PVF film has a downard trend after 1000 hours.

Less Color Change
Shelter-Rite Brite with Kynar vs. Standard PVDF, Acrylic and PVF (white)
Conclusion: Shelter-Rite Brite with Kynar has minimal color change over the equivalent of 26 years, and that level remains constant. PVF has a more significant color change at year 3, and then decreases due to chalking and as polymeric changes occur for the next ten years. After which, the color change shows a consistent increase given this polymer degradation. Both Acrylic and PVDF depict an increasing trend line as the top finishes degrade.
