Лако-красочные материалы — производство

The major use for block copolymers is in hot melt and solvent-based pressure sensitive adhesives. These pressure sensitive adhesives are most often used for tapes, and to a lesser degree, for labels. Solids contents of the solvent-based pressure sensitive adhesives are typically in the 40-60% range and are applied by a variety of converting processes, including roll coating, knife coating, and other similar processes. Block copolymers compounded as pressure sensitive adhesives are particularly effective on polyolefin foams, films, and laminates. These products are used in construction appli­cations, automotive padding and insulation, orthopedic devices, packaging, and book­binding.

Emulsion polymers are typically used in solvent — and water-based formulations, in both curing and noncuring applications. Many applications are similar to those listed for natural rubber applications, being used for bonding paper, fabric, wood, plastic, and other surfaces, often in spray grade formulations. Sulfur curable cements are used in laminating layers of fabric and rubber together for hose, belting, and tire fabrication. Carpets use a major quantity of SBR latex as a binder for backing materials. Emulsions also find extensive use as a binder for nonwoven goods, and in diapers and other personal disposables.

The construction industry uses several kinds of SBR polymers, in both solvent — and water-based compounds. Ceramic and tile bonding for floors and walls is one area, while solvent-based products for subfloor attachment to joists and panels to studs in building construction is a major area.
