Analytical Testing of Pressure Sensitive Adhesive Constructions - What Can It Reveal?

From Chemsultants International Network, Inc.

When a problem arises with a pressure sensitive adhesive (PSA) label or tape, often the first testing that is done is for physical properties, such as peel, tack, static shear and release. Depending on these results and other factors, the question that often comes up next is "Why?" This can lead to testing more chemical and structural in nature.

Industrial Adhesives
Industrial adhesives consist of hot melt adhesives, epoxy adhesives, polyurethane adhesives, sealants, thermoset adhesives, UV curing adhesives, silicon adhesives, acrylic adhesives and other related industrial products.
Epoxy Adhesives
Epoxy adhesives are chemical compounds for joining components. They require clean surfaces and are valued for their toughness and resistance to chemical and environmental damage.
Hot Melt Adhesives
Hot melt adhesives are solvent-free chemical compounds that are used to join materials. They can be repeatedly softened by heat and hardened or set by cooling, allowing parts to be removed or repositioned during assembly.
Acrylic Adhesives and Acrylate Adhesives
Acrylic adhesives and acrylate adhesives provide excellent environmental resistance and fast-setting times when compared to other resins systems. They are created by polymerizing acrylic or methylacrylic acids through a reaction with a suitable catalyst.
Pressure Sensitive Adhesives (PSA) and Contact Adhesives
Pressure sensitive adhesives (PSA) and contact adhesives adhere to most surfaces with very slight pressure. They are available in solvent and latex or water-based forms.
