Finished Adhesives and Sealants

RSS

Pressure-sensitive adhesives (PSAs) are a combination of several materials that come together to form a "construction." A PSA construction is a combination of layers including a facestock (label) or backing (tape), an optional primer coat, an adhesive, and a silicone release coating on a protective liner. The PSA construction—whether a label, tape or transfer adhesive—is manufactured through several coating and laminating steps, including liner-release coating, adhesive coating/drying/curing, optional facestock or backing primer coating, and lamination of the facestock or backing to the liner.

With ongoing advances in structural adhesive formulation, designers in every industry have increasing alternatives to mechanical fasteners for assembly of metal, composites, plastics, rubber, glass and more.

The harsh conditions of space place a set of constraints on the technologies that take us there. Of primary concern when it comes to space system design is the adhesive chosen to hold everything together. What does it take to perform in the vacuum of space, and why do silicone adhesives continue to be the adhesive of choice in many aerospace applications?

Standards are an important aspect of your business. If you manufacture, purchase, or use sealants or if you supply raw materials for sealants, your company relies on standards every day. R&D uses test methods and specifications to characterize, compare and develop products. Marketing and Sales use these same standards to advertise and promote products. When materials or sealants are purchased, they must comply with specifications.
