Johns Manville Roofing Systems Debuts DynaSet 1K Moisture-curing Adhesive and 1-Part PermaFlash Liquid-applied Flashing
Johns Manville announced that DynaSet 1K, a moisture-curing adhesive, and 1-Part PermaFlash, a liquid-applied flashing, are now available for shipment. With over three decades of experience producing modified bitumen, the team at Johns Manville understands the science of formulating commercial roofing systems that last and has released the new products for bituminous systems to help improve productivity on the roof.
“DynaSet 1K and 1-Part PermaFlash are designed to complement our extensive line of bituminous membranes," said Product Manager Jacob Heaps. "DynaSet 1K is a great adhesive option when there are concerns about solvents or odors on a job site, and the moisture-cure properties means adhesion isn’t impacted by moisture that may be present in concrete roof decks. Using it to adhere a SBS vapor retarder is a great option to help alleviate concerns of moisture entering the roof assembly from underneath. The 1-Part PermaFlash product will eliminate the need to mix components on site, allowing for a more efficient install around flashings.”
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 pounds). 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.
1-Part PermaFlash
1-Part PermaFlash is a 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 pounds each) or a 5-gallon pail (45 pounds). 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 Johns Manville's low-slope commercial roofing products with various reinforcements and installation options to fit your project’s needs. With the new offering of DynaSet 1K moisture-curing adhesive and 1-Part PermaFlash liquid-applied flashing, Johns Manville continues its commitment to offering high-quality products and services that can assist customers in completing the roof system efficiently.
