What Is A PolySealant?

This Spray Technology Has Tons Of Applications

What happens when you blend the efficiency of closed cell spray foam and the durability of sprayed polyurea? You get polysealants! Polysealants from Sealant Technologies, Inc expands during installation to fill cavities, gaps, cracks and penetrations throughout the building envelope. Polysealants help block air infiltration, enhance thermal performance and manage moisture on insulation jobs of all sizes. When these air sealants are sprayed, they create an airtight and moisture-resistant seal using two components that quickly bond to common building substrates for a flexible, long-lasting seal. Using a spray sealant to bridge the gaps in a building envelope or other structure can bring significant heating and cooling savings through reduced energy usage.

So what is an polyurethane sealant? A polyurethane sealant is an elastomeric material that allows for 25% – 50% movement. Sealants are used to fill gaps, to keep water and air at bay, to allow for expansion and contraction of building materials and to enhance aesthetics. Silicone and polyurethane are two popular types of sealants. Despite their common purpose, there are major differences between them.  The primary difference is at the chemical level. Polyurethane is an organic material. Silicone is an inorganic material. The effects of breakdown of silicone and polyurethane depend on the sealant’s chemical makeup.

Spraying A Brick Wall

Brick walls are sturdy structures that are not only functional in weight support, but ruggedly aesthetic. Brick walls can be found inside a residential dwelling, separating two rooms or as an exterior facade. However, brick is porous and is not easily sealed. Moisture can easily seep into a building through a brick. To prevent moisture, which can lead to mold and mildew growth, you’ll have find a way to seal air in order to stop the air transfer which is what a good air barrier will do.

Spraying A New Trailer

You don’t think about it much until you are about to purchase your next trailer or container and you begin to look at how they are constructed. The challenge is that in a lot of cases, most are built with cheap materials and the entire system leaks air. Like your house, if the trailer isn’t tight and if there isn’t any effort to make that trailer or container one solid envelope, then in the long run, it won’t work effectively.

Spraying An Old Wood Kiln

A conventional kiln is relatively simple to operate and maintain and it is a cost-effective technology for wood drying. The downside of this technology is energy efficiency. A conventional kiln consumes around 50% more energy than that required to evaporate the water. Energy consumption in a conventional kiln is required for moisture evaporation, heating the kiln and lumber, kiln ventilation, thermal losses, air leakage, and air humidification. Air barriers are effective ways to bring energy efficiency to any older wood kiln.

Spraying PVC Pipes

In the plumbing industry there’s been a way to prime and seal pvc pipe. It’s understood that “this is how you do it”. You purchase two cans of liquid; one primer and one cement, or plumbers’ glue. You open the primer and swab it on. You then open the cement and swab on the cement. AireBarrier does not work that way. A thin coat of this new sealant technology will create adhesion and block air and all of this can be done quickly at an affordable cost.

How Strong Is Your Sealant?

Adhesive Testing Can Give You That Answer

Adhesion is the bond strength measurement of a coating to a substrate. When an adhesive is bonded to an item or surface, numerous physical, mechanical and chemical forces come into play, which may have an effect on each other. These need to be tested before a product can be used. One of the primary features of closed cell polyurethane chemistry is the adhesion strength on almost any substrate.

Determination of the failure point can be critical for the final use of the material and the adhesive. There are a large number of different adhesive products, which require different testing methods to characterise the properties of the material. Some examples include substrates, glue, creams, gels, paints and varnishes and bonding of different materials together in layers, which all require a different adhesive test, some times called pull testing. We decided to test the Dry Wall Adhesive and the Black Can Foam to show you how strong these polyurethane foam sealants are.

Determination of the failure point can be critical for the final use of the materials, depending on the final product they have been designed for. Tests can also be done at different temperatures to simulate real world use for the materials. Material characteristics can change at high or low temperatures due to expansion and contraction. Hopefully this Spray Sealants Blog post can help you to determine which sealants you should choose when considering your next air sealing project.

TYTAN PRO Drywall Spray Adhesive

Drywall Nail Pops No Longer A Problem

We are pleased to announce our new partnership with Selena USA, maker of TYTAN brand foam’s, adhesives and sealants. They have some very exciting new chemistry which we will integrate into many of our spray platforms and we see a tremendous opportunity to bring a new way of air sealing to drywall installation.

Rudy Ruiz, owner of RR “Drywall and Painting” in Yorkville, Illinois, regarding his experience with TYTAN’s Drywall Spray Adhesive, and he says it has performed better than he could imagine. He’s been in the drywall and painting business for 40 years and has seen it all with drywall installation, taping and painting issues. He does a lot of drywall installation and painting work for D.R. Horton, one of the biggest residential builders in the country.”

There are two problems he’s had to deal with that are the most important quality issues on any drywall job: screw pops and visible seams. As he said “they can make or break a drywall company like mine.”

In the past, he was using a solvent-based adhesive that worked pretty well, and kept the screw pops and seams to a minimum. But when the VOC regulations changed, it forced drywall contractors to use latex-based drywall adhesives.

Moisture immediately became a problem and it meant screw pops and seams were a big problem as the latex-based glue just didn’t perform anywhere close to the solvent-based adhesive. He said “we were seeing up to 200 screw pops per house and visible seams everywhere. And this was happening after only a couple of weeks. It used to be six months, after the house had settled, before you would get the screw pops, but with the latex adhesive, we were seeing them before we had even finished painting. It was really affecting the bottom line.”

But the good news is once he started using TYTAN Drywall High Yield Adhesive, he found that it has eliminated his screw pop and seams problem. He says “I’m not easily impressed with the performance of any product I have to use, but I am very impressed with this TYTAN drywall adhesive.”

By using TYTAN Drywall High Yield Adhesive he has seen a reduction of screw pops from 200 per house to just 10! And he doesn’t blame the adhesive for those. And No Seams! He says this adhesive has eliminated the seams he used to see all the time.

He also says “we’ve done enough drywall installation now with TYTAN that it works very well, truly much better than any other adhesive I’ve tried since the EPA regulations came down.”

And, yes, it saves him money. It is less expensive than the solvent glue, and he doesn’t need to use nearly as many screws so he’s saving there as well. And, of course the call backs are way down. For this drywall contractor TYTAN Drywall High Yield Adhesive has been a game changer, and he’s even recommending it to others in the industry.
