SilverThane SA-2100: What is it and Why did we develop it?

With new SA-2100 as your designated urethane sealant/adhesive every drop is usable. No half-used tubes in the trash like you might get with other moisture cure urethane products.

SilverThane SA-2100 is a new two-part urethane sealant/adhesive.

SilverThane SA-2100 Adhesive/Sealant
We developed SA-2100 simply because we recognized that our mainstay epoxy resin products had limitations that made them impossible to use effectively as sealants and because they are poor bonders to many different types of plastics.  Furthermore, there is no way to make an epoxy resistant to UV (ultraviolet) degradation. 

To create SA-2100 we had to become knowledgeable in the art and science of formulating urethanes.  SA-2100 was designed to be superior to the one part moisture cured urethanes commonly used by boat owners and builders.  We spent almost four years acquiring the knowledge and overcoming the hurdles before SA-2100 became a viable product.  There was no roadmap and most urethane chemistry knowledge is closely held by those who possess it.     

What makes SilverThane SA-2100 unique is its ability to cure without the presence of moisture.  This two-part technology enables it to act as a sealant of any thickness and to cure uniformly across a glue joint film of any size.  This combined with its superior UV resistance and ability to stretch and rebound under load, makes it ideal for bonding dissimilar materials in outdoor, sun-drenched applications.

Unlike moisture-cured urethanes (3M 5200/4200, Sika 291 and West Marine 8200), SA-2100 does not cure in the cartridge after opening.  Users of these products appreciate the fact that a $14 tube of sealant becomes a $28 tube when you have to throw half of it away.

Finally, when formulating SilverThane SA-2100 we had the choice of using either petroleum or naturally derived (sustainable) products for some of the raw materials.  We chose to use natural products wherever possible so that about 20% of the mass of SA-2100 is made from bio-sourced materials.
