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.

Pressure-sensitive adhesives (PSAs) are versatile and commonly used adhesives that offer quick and easy bonding. They are called “pressure-sensitive” because they form a bond when pressure is applied, and they are ideal for applications where permanent or temporary bonding is required.
PSAs are formulated with a combination of synthetic rubber, acrylic, or silicone-based materials. These materials are chosen for their unique properties such as tack, peel strength, shear strength, and adhesion. The choice of material depends on the application and the required level of adhesion.
PSAs have many advantages over other adhesives. They are easy to use and require no additional curing time or heat to activate. They offer excellent adhesion to a wide range of surfaces, including plastics, metals, paper, and fabrics. They also offer good resistance to water, chemicals, and UV light.
At Cattie Adhesives, we offer a wide range of PSAs that can be customized to meet specific requirements. Our products are designed to provide the highest level of bonding strength, durability, and reliability. We have PSAs for both permanent and temporary bonding applications, as well as for use in high-temperature environments.
Our team of experts can help you choose the right PSA for your application and provide technical support throughout the bonding process. We also offer custom adhesive formulations and toll coating services to meet your specific needs.
Whether you need a PSA for automotive, construction, packaging, or any other application, Cattie Adhesives has the solution for you. Contact us today to learn more about our pressure-sensitive adhesives and how they can benefit your business.
