Nashua 361-11 Waterproofing Repair Tape

Printable View

Polyken/Nashua 361-11 Waterproofing Repair Tape is a tape with an aluminum foil backing/carrier which is coated on one side with a permanent butyl rubber adhesive. The tape forms a permanent seal with excellent adhesion to all surfaces. Nashua 361-11 is also extremely conformable and resistant to cold, heat, water, and sunlight. Its silver foil backing is paintable which helps match surfaces. Typically used for indoor & outdoor sealing and repair of gutters, roof alleys, eaves, hips and ridges. Can also repair seams and seal leaks, rips, and tears in pipes, hoses and in metal panels of trailers, shipping containers, and metal buildings.

We label the tape as Polyken/Nashua 361-11 in the product description because they are co-brands owned by Berry Plastics (the parent company of Nashua, Polyken, Ludlow, Patco, etc. tape brands). The core of the tape can be labelled as either Polyken or Nashua depending on the runs we get the cut rolls from. Made in the U.S.A.

* Multiple cases may be shipped per package in order to minimize the charge for shipping.
