About Permatite

Permatite is a brand of Edge Adhesives with more than 50 years of experience formulating and refining high-performance sealing products. Trusted across a broad range of industries — from on- and off-highway vehicles and equipment to sheet metal fabrication, architectural building products, and HVAC systems — Permatite has built a reputation for consistent quality, low minimums, and short lead times that professionals and manufacturers rely on.

What Permatite Makes

Permatite's core product lineup covers three closely related families: sealants, tapes, and sponges. Each product is custom-formulated and engineered to excel in specific applications, with a focus on maximum performance and longer product life.

• Sealants: Permatite offers a comprehensive range of sealant chemistries, including acrylic latex, acrylic, butyl rubber, co-polymer sealant/adhesive, fire-retardant, and self-leveling single-component elastomeric formulations. Whether a job calls for sealing ductwork, glazing, or vehicle assemblies, there is a Permatite formulation designed for the task.
• Tapes: The tape lineup includes ultra-durable butyl rubber tapes, sealing and patching tapes, and cork insulation tapes — all engineered to bond to a wide range of substrates including metal, glass, plastic, wood, and masonry. Key product lines include the 250-H Butyl, 4-Bolt Flange, Insta-Seal, and Cork Insulation tapes.
• Sponges: Permatite's Dortite and Dortite Xtra sponge products are formulated for excellent memory and long-term performance, making them easy to use and highly reliable in demanding sealing and gasketing applications.
