Gear Aid Seam Grip + Sil Silicone Tent Sealant ( Silnet ) 28g Tube

Seam sealing with Seam Grip SIL is the best way to keep moisture out when using a silnylon (silicone-nylon) tent. Previously known as SIL Net, this clear sealant dries to a flexible rubber that works on all silicone treated gear including nylon tarps and ultralight backpacks.

Silnylon cannot be factory taped like PU Nylon due to its physical properties, it requires you to seal it outdoors with silicone.

Why would we use this fabric with seemingly obvious flaws in the more advanced Lanshan PRO?

It was a decision we made in terms of fabric aging time, tear strength. We think the places that professional hikers reached will be harsher and have stronger UV rays, which puts higher demands on the aging and strength of the fabric.

The aging performance of Silicon-PU Nylon in this data is based on our years of repairing tents in the Chinese market, including PU Nylon of brands such as MSR\BigAgnes\3FULGEAR, etc.

Since we haven’t repaired the aging SilNylon tent, the aging performance of SilNylon is based on feedback from our customers and users of backpackinglight.com

This data is derived from our experiment on one-way tearing of single-ply fabrics with incisions.

SilNylon will not be torn apart like paper under the force that exceeds its tearing strength. The slippy fibers will go together and lines up into a strong anti-tear force, and although the tent is damaged at this point, it will not collapse and can continue to provide protection for the user.

This data is derived from our test using the WX Air PowerPressure device, tested at 25 degrees Celsius. The video of the experiment is published on our Youtube channel.

The water proof that can effectively prevent raindrops piercing through is 1000-2000mm, which is why we try our best to make SilNylon to this value. The water resistance pressure of PU Nylon is far beyond the actual use requirement because we found in our study that only by increasing the thickness of PU layer to this value, it is possible for PU tent to reach 5 years of life.
