Abstract: The present invention is a combination of sodium hydroxide, borax, boric acid and potassium hydroxide forming a liquid that can be added to pearl starch and water in a single step to form an adhesive with proper viscosity, gel point and tack for manufacturing corrugated paperboard. This combination eliminates the danger associated with handling the sodium hydroxide independently, as the borax, boric acid, and potassium hydroxide act to buffer the sodium hydroxide to reduce exposure risks. The additive comprises by weight: a) from about 40% to about 85% sodium hydroxide; b) from about 10% to about 30% borax; c) up to about 25% boric acid; and, d) up to about 25% potassium hydroxide.

Abstract: Methods for providing a cable closure enclosing a cable splice include wrapping a flexible wrap including a gel layer and a flexible support layer around the cable splice with the gel layer adjacent the cable splice. The gel layer may have an adhesion-reducing substance applied on at least part of a surface of the gel layer facing away from the flexible support layer and a removable cover layer may be applied to a surface of the gel layer facing away from the flexible support layer on which the adhesion-reducing substance is not applied. The wrap is gathered into overlapping wrinkles around at least one longitudinal end of the cable splice without applying heat, other external energy source or catalytic agent to allow the gel layer to seal the at least one longitudinal end of the cable splice.
