Consumer and industrial products succeed in the marketplace because their performance meets expectations; adhesive and sealant materials are no exception. Ease of handling and use, ability to fasten together and seal, straightforward cleanup after application, and longevity for reliable performance are all points of evaluation that distinguish top performers from average products.
Viscosity measurement has long served as a simple quality control check for quantifying flow behavior of material during placement. More recently, compression/tension testing has become an important way to assess tack and hardness. Tension evaluates effectiveness of fastening materials together by pulling them apart after bonding, while compression quantifies protection against penetration by measuring the force needed to puncture the material.
