Abstract
A corrosion resistant seaming tape includes a metal layer capable of blocking selected frequencies of electromagnetic radiation arranged on a polymeric substrate and covered with adhesive that protects the metal layer and prevents it from corroding. Also disclosed is a method of sealing a seam between adjacent edges of two adjacent pieces of window film including an internal metal layer by applying a polymeric film to the seam.
Claims6
A corrosion resistant seaming tape including a metal layer capable of blocking selected frequencies of electromagnetic radiation, comprising:
- (a) a polymeric substrate having opposed first and second major surfaces, and opposed first and second side edges;
- (b) a metal layer arranged on the substrate first major surface, the metal layer having first and second side edges arranged in spaced relation with the substrate first and second side edges, whereby the substrate first major surface includes a central surface portion covered by the metal layer and further includes a pair of side surface portions adjacent each side of the central surface portion that are not covered by the metal layer;
- and
- (c) adhesive arranged on the substrate first major surface over the metal layer and arranged over the substrate side surface portions, whereby the metal layer, the metal layer first and second side edges, and at least a portion of the substrate side surface portions are coated with adhesive, wherein the tape is optically clear.
