Butyl rubber and asphalt adhesives compete in applications such as flashing applications. Table 5.8 shows a side-by-side comparison of those two adhesives indicating advantages for the butyl rubber over rubberized asphalt adhesive.

Generally, systems developed in the USA favour a combination of polyethylene with either butyl-rubber or hot-applied mastic adhesives, the latter consisting of a blend of rubber, asphalt and high molecular weight resins. In European and Far East coating plants, epoxy type primers and hard ethylene copolymer adhesives have been successfully employed. 

While this book was in its final preparation stage, two additional types of adhered sheet linings for chemical exposures have come to our attention. One is a sheet with, as the exposed face, a Tedlar(sf film adhered to a layer of rubber-asphalt blend. The sheet is applied with rollers to a substrate surface that has been coated with an adhesive primer. Sheet edges are butted with an adhesive lap strip of Tedlar applied over the joint to protect it. This is a proprietary product presently available from only one source, which will supply particulars of the application procedure and chemical resistance tables upon request. 

The insulating power and chemical resistance of the glass block allows for a thinner lining and better membrane protection for pickle tanks where stability is not a concern. The tank is first lined with the rubber membrane, the block is bonded over that with its urethane asphalt adhesive/membrane and finally a course of acid-resistant brick laid in acid-resistant mortar is placed over the block for mechanical protection.

The application of MBRs vary with the system. SBS roof systems have been developed to be applied with hot asphalt, heat or rubber-based adhesives. APP roof systems are commonly applied using heat, but may be applied by cold adhesives such as epoxies or acrylates. 

Polymeric materials are easy to synthesize. Therefore, the final products are substantially more economical than other t) es of building materials. Synthetic polymers are widely used in the construction industry. Some of the organic polymer materials used in the building industry are fibers, rubber, plastics, adhesives, sealants, coatings, and caulking compounds. Polymers are also used as modifiers to improve the properties and performance of some construction materials, such as roofing and road asphalt. 

Examples of the fatty acids are oleic (c -9-octadecenoic) and linoleic (c ,c -9,12-octadecadienoic) acid. The major constituent of rosin acids is abietic acid. Uses of tall oil are tall oil rosin (31%, for paper size, protective coatings, adhesives, inks, and rubber), tall oil fatty acids (30%, in protective coatings, soaps, and inks), tall oil pitch (30%, in fuel, binders, coatings, rubber modifiers, asphalt, sizing, inks, and hardboard impregnation), and distilled tall oil (9%, in soaps, coatings, flotation, and board impregnation). 

Protein glues are good for bonding rubber to steel, cork to plywood. Asphalt makes a good adhesive for roofing of homes. 

Asphalt—mbber is mixed and applied to roadways by several techniques. In one method, mbber and asphalt are mixed at ca 175—220°C for one to two hours. The hot mixture is applied to the roadway and covered with a layer of stone chips to form a chip seal. The mbber cmmb consists of scrap tires ground into particles less than 2 mm in diameter. Rubber-modified asphalt is also used for waterproofing membranes, crack-and-joint sealers, hot-mix binders, and roofing materials. The mbber improves asphalt ductility and increases its softening point. The aggregate adhesive bond is stronger, and the asphalt lasts longer. Production of rubber-modified asphalt has increased from 405 t in 1970 to 27,000 t in 1980 (41). Typically, about 2 t of mbber is used for 1 km of roadway. If it is assumed that asphalt—mbber contains ca 25% mbber and 75% asphalt, the potential demand for scrap mbber would be ca 40,500 t/yr, or ca 2% of the amount available. 

Crumb rubber can be mixed with other materials to make new products, including plastic floor mats and adhesives. It can also be mixed with asphalt as an additive to make cement products.

A large apphcation of latex is in blends with asphalt to produce a waterproof membrane on cinder block and concrete walls. Here, as well as when incorpevated into concrete mortars, the rubber fraction produces better adhesion, durability, and temperature expansion tolerance than the asphalt or mortar base alone.

Hot asphalt applications had been used for many years in concrete tanks, inner lined with brick for similar service, and also, of course, unlined wood tanks made from timber, and small pickling tanks made by hollowing out cavities in granite blocks. But the use of hot asphalt as a liner for steel tanks had been unsatisfactory due to the erratic cold flow of the asphalt which demonstrated selective adhesion to steel and so would tear and open cracks in the membrane system in the areas of cold flow below the points where it adhered. To overcome this difficulty, a number of inventive persons experimented with the manufacture of asphalt sheet lining materials, similar in form to the sheets of natural rubber, in which the asphalt was compounded with various admixtures, including rubber. These asphaltic compound sheets were then warmed sufficiently to make... 

Sheet membrane linings are usually shipped in rolls. Exceptions include plasticized-unplasticized vinyl laminates, specially compounded asphalt and asphalt and rubber compounded sheets, usually shipped flat in cartons or boxes. These are applied to properly prepared surfaces with an adhesive that may be air-cured or heat-cured. At all events, so far as storage is concerned, temperatures above freezing and under 100°F are usually not matters of concern, unless the manufacturer or applicator so advises. Water and dirt, however, damage these materials so they should be stored in a clean storage area, off the ground and under cover.

These adhesives have been found to adhere strongly to metals, glass, wood, ceramics, masonry, asphalt, leather, and plastics like polystyrene, phenolics, polycarbonates, ABS, cellulose acetate, polyesters, rubbers, and some polyolefins. In general, the most favorable results are noted in the bonding of steel and aluminum, perhaps because the bond strengths are more easily observed before substrate failure.

Floor underlayments are utilized to produce a level and smooth surface before placing vinyl tile, asphalt tile, rubber tile, or other resilient flooring materials. Acrylic latex modified underlayments are ideally suitable for leveling floors prior to the installation of these surfacing materials, since these underlayments provide an excellent substrate for bonding purposes, as well as offering good chemical resistance to tile adhesives and solvents which some of them contain. 

In addition to widespread use as a blend in asphalt/rubber sealants for roofing and other construction applications, reclaim rubber adhesives have been used as an insulation adhesive, as a pipe wrap adhesive, and as an ingredient in some pressure sensitive adhesives. Of interest is the fact that virtually every telephone installation in the United States before 1985 that required a cable splice used a reclaim rubber adhesive.
