The global pandemic has accelerated demand for manufactured goods of many types, as consumers stay home and manufacturers continue to operate as essential businesses.
A range of rheological equipment is available with a variety of spindle geometries to properly perform quality control analyses of various adhesives and sealants.
Formulators are constantly updating their adhesive and sealant formulations; consequently, manufacturers of the equipment used to measure the adhesives’ and sealants’ flow behavior properties must keep current with these new formulations.
The new TA-LTT loop tack tester can be used with this company’s CT3 tester. The tester is designed for testing the adhesive strength of materials per ASTM D 2979.
Adhesive nasal strips were first created in the early 20th century not for people but for racing horses. Horse trainers found that their horses raced better with the strips in place.
For many years, the adhesives and sealants industry has used a range of standardized test methods to ensure the quality of products for industrial applications.
Testing pressure-sensitive adhesives under standard conditions of temperature and relative humidity is always a preferred means to compare data from lab to lab and from lot to lot, but it is sometimes necessary to evaluate the performance of an adhesive under conditions that it would encounter in the field.

Many adhesives exhibit different properties when subjected to variations in temperature. Some of these adhesives are thermoplastic. They soften when heated and become more brittle when cooled. [In the case of pressure-sensitive adhesives (PSAs), the nature of the bond is nearly always thermoplastic.] If for the sake of this discussion we limit our testing to tack, peel and shear, we can develop a series of observations that can be applied to most testing situations.
