What is Pressure Sensitive Adhesive?
Pressure Sensitive Adhesive, also called, “PSA” or “Self Stick adhesive” is a flexible adhesive that bonds to a variety of substrates when applied to clean and dry surfaces with pressure. Pressure Sensitive adhesive bonds are formed with Pressure – PSA’s Do Not Require solvent, water, or heat to activate the adhesive. The bond strength is directly influenced by the amount of pressure used to apply the adhesive to the surface. PSA’s are a great choice for difficult to bond, low energy substrates.
PSA’s are unique because they do not solidify to form a hard material; PSA’s remain permanently tacky and can “Wet-Out” substrates on contact. The bonds are formed by bringing the PSA adhesive in contact with the substrate and applying pressure to form a bond. PSA’s can be formulated for both – Permanent & Removable bonding Applications.
Benefits of Pressure Sensitive Water-Based Adhesives
Key Features
– Provides a smooth, quiet and magnetic-like peel.
– FDA compliant for direct food contact applications.
– Repositionable.
- water-based pressure formulated to provide a repositionable seal with little diminishment in seal strength provided there is no contamination of the PSA.
- FDA compliant for use in direct food contact applications. Seal strengths will vary with
specific coating, film treatment and processing. - Pressure Sensitive Water-Based Adhesives for Resealable Packaging.
- Reseal available.
- Slot and roll transfer coat.
- Permanent and removable pressure sensitivity.
- Cross-linkable to become stronger or removable.
Cattie Adhesives manufactures a full line of high performance Pressure Sensitives; available in several degrees of Color, Peel Strength, Tack, Shear Strength and Viscosity.
Our Pressure sensitives can be supplied in the form of a Water based Acrylic Adhesive, Solvent based Adhesive, Hot melt PSA or UV Radiation Cured PSA.
PSAs make up the largest market share of the adhesives business. Our PSA’s can be formulated as a Permanent or Removable grade adhesive and Bond to a wide variety of substrates. The primary raw materials used in formulating our PSA’s are Acrylics, Silicone, Rubber, SBS, Polyurethane, Vinyl Acetate and Epoxy.
We have the capability to Coat our Pressure Sensitives onto many different substrates including – felts, films, foams, release liners, magnet, papers, plastics, and textiles; for various Medical Tape and Industrial Tape applications.
