PRESSURE SENSITIVE ADHESIVES
Pressure sensitive adhesives can be supplied dissolved in organic solvents, as an aqueous dispersion, as a hot melt, or coated on release liner as tape. Liquid applied (solvent or water based, hot melt) pressure sensitive adhesives can be applied in bead or ribbon, sprayed, or roll coated. After coating (and drying of solvent or water based systems), parts can be bonded or the adhesive covered with release liner for bonding later. The adhesive can be coated in a pattern to provide bonded and unbonded areas, e.g. assembly of membrane switches, filter frames. Pressure sensitive adhesives are often used to temporarily hold components like gaskets in position during assembly.
The special feature of pressure sensitive adhesives is that they do not solidify to form a solid material, but remain viscous. As a result, they remain permanently tacky and have the ability to wet surfaces on contact. Bonds are made by bringing the adhesive film in contact with the substrate and applying pressure. If inadequate pressure is applied or the processing temperature is too low, bonding faults such as bubbles or detachment can occur. Since these adhesives are not true solids, the strength of pressure sensitive adhesives decreases when the temperature is increased. Pressure sensitive adhesives also exhibit a tendency to undergo creep when subjected to loads. They are typically formulated from natural rubber, certain synthetic rubbers, and polyacrylates.Astro Packaging is a leading supplier of pressure-sensitive adhesive technologies to the tape and label industry. Our market-focused customer service and technical consultants are problem solvers who have years of experience with tapes and labels. We work with you to assure that you achieve the best adhesive technology for your product, along with optimized operating efficiencies.Pressure sensitive adhesive (PSA, self adhesive, self stick adhesive) is adhesive which forms a bond when pressure is applied to marry the adhesive with the adherend. No solvent, water, or heat is needed to activate the adhesive. It is used in pressure sensitive tapes, labels, note pads, automobile trim, and a wide variety of other products.
As the name "pressure sensitive" indicates, the degree of bond is influenced by the amount of pressure which is used to apply the adhesive to the surface.
Surface factors such as smoothness, surface energy, removal of contaminants, etc. are also important to proper bonding.
PSAs are usually designed to form a bond and hold properly at room temperatures. PSAs typically reduce or lose their tack at cold temperatures and reduce their shear holding ability at high temperatures; special adhesives are made to function at high or low temperatures. It is important to choose an adhesive formulation which is designed for its intended use conditions.
