Elastocoat . [BASF AO] Polyurethane casting and coating systems for mold making, tire filling, furniture edges, wear-resistant floor coverings. 

All floors must have a smooth, nonporous surface that is intact and cleanable. Wood floors can be coated with paint or polyurethane, or covered with tile or linoleum. Vinyl and linoleum can be waxed. This should be done after cleaning and visual examination but before final clearance. 

Adhesives for Plastic Floor Covering. Solvent-free adhesives based on acrylic and vinyl acetate - ethylene - acrylic emulsions are used for bonding vinyl, synthetic rubber, and polyolefin flooring. Solvent-containing contact adhesives (rubber- or polychloro-prene-based) still are used for some applications (e.g., stairs). When water resistance is required, reactive polyurethane or epoxy resin adhesives are preferred to waterborne emulsions.

Floor structures of subway electric cars made of aluminum are shown in Fig. 47.7c. PVC floor coverings are bonded with a two-component polyurethane adhesive on polyurethane-coated floor plate of aluminum hollow extrusions.

The term floor-covering adhesives denotes all materials for laying flexible floor-coverings. These include secondary and unitary backed carpets, felt backed vinyl, vinyl composition tile (VCT), homogeneous vinyl sheet, rubber, and various vinyl and polyurethane backed carpet tile products. Rigid coverings, such as natural stone, ceramic and parquet, are not included here. 

The thermal insulation materials used in the walls, ceilings, and floors of refrigerated storage are usually combustible, such as polyurethane and polystyrene foam, and could present an additional fire hazard. The insulation should be covered with a noncombustible barrier material a V2-in (1.3-cm) thickness of Type-X gypsum board or cement plaster is often used for this purpose. Where the floor is insulated, the floor insulation should be covered with a layer of concrete. 

The floor of the storage site should be made of sealed cement, glazed ceramic tile, no-wax sheet flooring, or another easily cleaned material. Carpeting, wood, soil, and other absorbent floors are difficnlt or impossible to decontaminate in case of a leak or spill. For ease of cleannp, shelving and pallets should be made of nonabsorbent materials snch as plastic or metal. If wood or fiberboard materials are nsed, they should be coated or covered with plastic or polyurethane or epoxy paint. 

In this book I have confined discussion to those polymeric materials which are cured by chemical reaction and which have found widespread application in the construction industry. As such, the book covers materials based on epoxies, polyurethanes, silicones, polysulphides, alkyds and polyesters. In addition, there is a chapter on hybrid polymer systems and one on acrylics. It is true that acrylic emulsions are not strictly thermosetting polymer systems, but their widespread use and importance made their exclusion difficult. These materials find use as coatings, sealants, adhesives, grouts, flooring compounds, repair compounds and waterproofing agents. 

Butyl benzyl phthalate is a plasticizer added to polymers to give flexibility and softness. It is used extensively in polyvinyl chloride and in cellulose plastics, polyvinyl acetate, polysulfides, and polyurethane. Also used in flexographic inks for food packaging applications and acrylic coatings, profile extrusions, slush moulding, film and sheeting, coated fabrics, floor and wall coverings, vinyl foams and plastisols for car sealants. 

The majority of all antimicrobial additives are used in flexible PVC. The remaining portion is used in polyurethane foams and other resins. PVC applications using antimicrobials include flooring, garden hose, pool liners, and wall coverings. 

The fire started in a partitioned balcony area where two seats were alight when it was discovered. The seating was raised to enable people in that area of the club to see the floor shows. The seating was filled with highly combustible and toxic polyurethane foam and it was covered with combustible vinyl covering.
