The second sheet lining is also a fluorocarbon—Halar , but made entirely of this basic material. Though quite expensive, this material has probably the best overall chemical resistance of any of the generally available sheet linings. It is adhered to the substrate with a rubber-type adhesive, and though Halar can accept surface temperatures of 300°F and above without damage, the use of the sheet must be limited to the 220°F range due to the thermal limit of the elastomer adhesive. Joints are butted, tooled to accept a weld strip, and then a narrow strip is heat-sealed over the joint. Full data on the material, its installation and chemical resistance is available from the manufacturer.

The classic test for tack of a pressure-sensitive adhesive film is the rolling ball tack test. Here a ball is rolled down an inclined plane onto a film of the adhesive. The length the ball travels across the film before stopping is a measure of the tack of the film. This test gives a good indication of tack with elastomer adhesives but is unreliable with water-based systems. 

An important and versatile family of polymers, whose diverse uses include foams, fibers, elastomers, adhesives, and coatings, is formed by the interaction of diisocyanates with diols.
