Construction specialty adhesives

The Adhesive The choice of the proper adhesive for one s label is quite obviously of major importance. The two t3rpes of adhesives generally used for pressure sensitive label construction are rubberbase and acrylic emulsion. In addition, most converters of label stock offer a variety of specialty adhesives to meet particularly demanding applications. Some of the terminology associated with pressure sensitive adhesives is as follows.

Many industrial free-radical polymerization processes have been developed and commercialized for a variety of monomer and polymer types. A variety of monomers and polymerization processes have been commercially exploited. Further, there have been significant developments in synthesizing polymers with controlled architectures using free-radical polymerization during the last two decades. Materials synthesized include block copolymers, graft copolymers, and radial polymers. These materials find use in many common industrial and household applications such as adhesives, paints and coatings, textiles, nonwoven fabrics, personal care products, wallpaper, construction materials, specialty additives, and many other areas.

Tires are the largest consumer of synthetic rubber. Automotive components and tires together account for nearly 70% of synthetic rubber consumption. Additional consumption is found in miscellaneous mechanical goods, plastic composites, and construction applications such as roofing, vire and cable covers, and adhesives. For SBR specifically, passenger tire production consumes approximately 50%, truck tires and tire retreading a further 20%, and the balance is in specialty tires, automotive and non-automotive components. Polybutadiene consumption is similar to SBR with tires accounting for nearly 75% of total polymer production. 

Glycerol esters of rosin are generally recognized as safe substances and approved by several FDA notifications as direct and indirect food additives. They are broadly used in manifold adhesive applications, such as pressure sensitive (PSA) tapes and labels, sealants in flooring and construction, lithographic ink resins, roadmarking resins, bookbinding, as well as other specialty applications. 

Adhesives. Contact adhesives are blends of rubber, phenolic resin, and additives supplied in solvent or aqueous dispersion form they are typically applied to both surfaces to be joined (98). Evaporation of the solvent leaves an adhesive film that forms a strong, peel-resistant bond. Contact adhesives are used widely in the furniture and construction industries and also in the automotive and footwear industries. The phenolic resins promote adhesion and act as tackifiers, usually at a concentration of 20-40%. In solvent-based contact adhesives, neoprene is preferred, whereas nitrile is used in specialty applications. The type and grade of phenolic resin selected control tack time, bond strength, and durability. 

General. Solid SBRs play an important role in the adhesives industry. They are used in many general purpose and specialty applications, including general purpose construction adhesives, tape adhesives, and pressure-sensitive adhesives. 

Specialty absorptive and composite dressings are composed of various combinations of foams, gels and absorbent fibers such as cellulose, cotton or rayon. They may be laminates with or without an adhesive border, and may be covered with a moisture permeable, bacterial barrier. Constructions are designed for management of wound fluid level and enhanced ease of use.
