HyKote™ SEBS Mastic
HyKote™ SEBS Mastic is a flexible, high performance, watertight, puncture-resistant ready-to-use single component fluid applied styrene ethylene butylene styrene (SEBS) reinforced liquid resin. HyKote™ SEBS Mastic is used in various restoration and waterproofing liquid applied membrane applications.
When combined with a spun-laced high performance polyester fleece scrim, SEBS Mastic will form a monolithic, self-flashing and self-adhering reinforced waterproofing membrane for a variety of roofing restoration applications, such as: EPDM, Granular surfaced SBS modified bitumen, Hypalon™, APP, KEE (Elvaloy®), PVC, Smooth Surfaced Asphalt BUR, Galvanized metal, Kynar®, Plywood, TPO, Smooth Surfaced Coal Tar Pitch BUR, Spray Polyurethane Foam, and Concrete.
HyKote™ SEBS Mastic can be utilized in the following applications where it may or may not be used in concert with polyester reinforcement. Reinforced (R) Non-Reinforced (NR).
- Metal roofs preparation process at horizontal seams (R), vertical seams (NR), penetrations (R), flashings (R), and fastener heads (NR)
- Restoration repair and reinforcement of expansion joints, transitions, and curbs (R)
- Repairs (reinforced as necessary)
- Flashings (R) (use SEBS Mastic for angles less than 90˚) (use SEBS Mastic and Reinforcement for 90˚ angles)
- Seam repair (R)
- Vertical flashing seams (R) HyKote™ SEBS Mastic is available in white or silver in 5–gallon re-sealable pails.
HyKote™ SEBS Mastic is manufactured in our ISO 9001:2008 Registered facility located in Seville, Ohio.
