What is DynaSet 1K? 
DynaSet 1K is a one-part, solvent-free, moisture-curing adhesive designed to install JM SBS membranes.
DynaSet 1K is available in a 5-gallon pail (45 LBS).
It can be installed using traditional, cold adhesive application methods or can be applied in a ribbon application to allow for venting moisture below SBS vapor retarders in bituminous and single-ply systems.
The moisture-cure properties provide excellent green strength and a quick set-up during install, and potential ambient moisture in concrete decks will not adversely impact the adhesive's properties. This allows the contractor to better set schedules with a lower risk of variable measurements of moisture in the concrete that can cause project delays.
What is 1-Part PermaFlash?
1-Part PermaFlash is a unique one-part, elastomeric, liquid-applied flashing material designed for flashing penetrations on granulated JM bituminous membranes.
1-Part PermaFlash is available in a box with two 1-gallon pails (9 LBS each) or a 5-gallon pail (45 LBS).
It requires no mixing of components on-site, reducing the risk of operator mixing errors and helping to ensure the correct installation of the product. 1-Part PermaFlash cures to a durable elastomeric film with exceptional bonding to a variety of penetrating materials.
The bituminous SBS system is the most customizable of our low-slope commercial roofing products with various reinforcements and installation options to fit your project's needs.
