What is the Initial Tack? 


One of the important properties of a pressure-sensitive adhesive is the initial tack

When talking about initial tack, we refer to the strength of a material’s stickiness when it first comes in contact with an adhesive to a surface to which it is to be glued to. Tack helps us measure how fast a bond is formed when first adhering to a material or a surface. Adhesives, coatings, and printing inks and toners all have an initial tack level.

 The initial tack is like many little hands from the glue grab the substrate.  It defines the ability of a wet adhesive to hold materials in place while the adhesive cures, without the material, slipping or moving. More force is needed to be exerted when removing from a high initial tack adhesive.
