Product Description
Nashua 357 is a premium-grade duct tape built for tough contractor and industrial jobs. It uses a PE-coated cloth backing with an aggressive natural rubber adhesive for strong stick on a wide range of surfaces—including challenging/rough materials—and it’s designed for durability with abrasion and puncture resistance plus a crisp, straight tear for fast application. Ideal for seaming/sealing heavy PE sheeting, waterproof repairs, heavy-duty packaging/bundling, securing underlayment materials, tarps, and media-blast protection
