Seam Grip Urethane seam sealant creates a permanent, waterproof seal on hundreds of fabrics and materials. The unique patented formula easily penetrates stitching and seals gaps, leaving a thin, clear film that prevents water migration.
The resulting seal is extraordinarily flexible, elastic and resistant to temperature extremes and stretches over 100% with no loss of strength or adhesion.
Seam Grip is also a powerful adhesive, bonding materials and repairing tears and holes. Repairs made with a single application generally last the life of the item.
Seam Grip is ideal for thousands of sealing, repair and adhesion applications and is especially well suited to harsh environments.
