Seal Design Launches Nitrogen-Infused Sealant

December 13, 2011 by · Comments Off on Seal Design Launches Nitrogen-Infused Sealant 

Seal Design LLC recently introduced its Seal-Tite hot melt sealant for RV windows, doors and hatches that can “reduce manufacturers’ sealant cost by 30%,” according to a press release.

Nitrogen gas is infused into the sealant material, volumizing it and enabling the material to spread farther and seep more effectively into small gaps to create an impervious seal. Seal Design, a subsidiary of Dicor Corp., said that because of the deeper penetration, manufacturers save on material costs.

The new closed-cell, gas-sealant mixture is easier to compress when solid and also less likely to over-compress, retaining good rebound or reflexive qualities. It also reduces sagging to maintain uniform thickness while still offering a seal that is as durable as the non-infused material.

The caulk and putty replacement is a highly stable sealant that can be applied by the manufacturer quickly and accurately with a hot-gun or robotic process that keeps bleed waste and cleanup to a minimum, according to the release.

Also, unlike caulk and putty tape, Seal-Tite does not crack, shrink or deteriorate over time, maintaining a solid, worry-free seal. In addition, it is a green product manufactured in accordance with Energy Star and American Architectural Manufacturers Association specifications.

The volumized product will let RV manufacturers do more with less material, and take advantage of a newly developed robotic application option that applies the sealant with consistent automotive quality faster than ever, said Greg Kelly, general manager of Seal Design.

“We’re talking a fraction of the time it would take for an assembler to seal a fixture with standard caulking. It can replace the manufacturer’s inventory of several different kinds of caulks and sealants,” Kelly noted. “With nitrogen infused Seal-Tite applied robotically, you get a consistent, automotive quality result — a precisely placed, solid, durable seal that’s going to stand the test of time and weather,” he said.

The infused sealant also sets up faster for increased line speeds and production rates.

Seal Design’s New Sealants Treat Entire RV

Simpler is better. This is the message Seal Design has been sending out to the RV industry since it introduced a trio of breakthrough sealant products at the National RV Trade Show this past December. A number of RV manufacturers are now integrating the new RV sealants into prototype units and assembly processes. Seal Design is an affiliate of Dicor Corp.

The three sealants are Perma-Fit extrusions, Seal-Tite hot melt sealant, and Touch-N-Seal spray foam insulation. “These three component products can literally seal and insulate every single application in a recreational vehicle,” said Greg Kelly, general manager of Seal Design. “They can replace most all of the SKUs now used by manufacturers. We’re aiming for nothing less than a simple but complete solution for water leaks and other sealant failures.”

All three sealants are tested and proven performers in other industries but have never been used for RVs.

So far, prototype work for Seal-Tite and Touch-N-Seal has gone well with several manufacturers, said Kelly. Seal Design is also working closely with manufacturers to efficiently integrate these products into their production processes. “We’ve always been a leader in not only finding innovative products for the industry, but in working closely with manufacturers on the best way to integrate our products into their production processes,” said Kelly. “We don’t just drop them off at the loading dock and disappear. If we sell it to you, we’re going to make it work for you.”

Seal-Tite comes from the architectural glazing industry as a hot melt application that replaces putty, rubber, tapes and other such sealants. It is made of 97% solid cross-link polymer to create a long-lasting seal that does not bleed, sag or shrink. Applied with a hot gun, manually or robotically, it cures quickly and can significantly reduce application time and waste for the manufacturer.

Touch-N-Seal is from the construction industry as a spray-in foam insulation that replaces fiberglass to provide better R-Value (7.12 per inch vs. 3.2) and a tighter seal against water infiltration, while also improving the unit’s structural integrity. Additionally, it takes up little storage space compared to the rolls of fiberglass material needed for the same job.

Perma-Fit is a non-cellular extrusion from the automotive industry that is a much more durable extrusion seal for baggage-utility doors, slide-outs, moldings and molding substrates than the foam rubber that’s used today.  It is a solid thermoplastic that will not shrink, become brittle or loose its elasticity and shape over time. So it will seal as well 10 years from now as it does on day one.

“These products are prime examples of the way Dicor companies seek out innovative solutions from other markets to help build a better RV — in this case more energy efficient and leak-proof units — while also working with manufacturers to create better production processes,” said Kelly. “Our work with these products has confirmed that they can provide a new level of RV quality that the RV consumer will appreciate. That bodes well for all of us in the industry. It’s as simple as one two three.”
