Resin-based flooring

Two-component epoxy resin water thinned dispersions are now being used as floor sealers. They have good adhesion to concrete as well as good chemical resistance. However, the particle size of the dispersion is comparatively large (approximately 1-1.5 microns) and consequently penetration into good-quality concrete is minimal and an on-surface seal is obtained. However, with porous low-quality concrete substances, considerable binding/strengthening, etc. of the surface can be achieved with water-dispersible epoxy resin-based floor sealer.

Liquid resin-based systems which, like the chemical surface hardeners, penetrate into the surface of a concrete topping or directly finished slab and protect the acid-susceptible cement matrix from attack and, at the same time, strengthen the surface of the concrete are now being increasingly used. These in-surface seals leave the slip resistance of the concrete floor virtually unchanged but the treated floors are easier to clean and are more durable. 

Self-leveling These are generally based on solvent-free epoxy and there are a number of proprietary products available. Generally, they are 3-8 mm thick, but if the base floor is too rough, it is advisable to first level this with a cement/resin screed. 

Oil-containing adhesives might emit fatty acid oxidation products like saturated and unsaturated aldehydes which can contribute to odor (Wilke, Jann and Brodner, 2004). Adhesives on a phenol resin base have been found responsible for odor annoyance in several office buildings in former East Berlin. Alkyl-substituted phenols, methyl, dimethyl and ethyl phenols, some of which have very low odor thresholds, have been detected in indoor air as well as in different floor samples and were most likely responsible for the off-odor (Kirchner and Pernak, 2004). 

Uses Epoxy base resin in flooring, casting, laminating, and high-build solventless coating appiics. 

Some of the earliest major applications of adhesives in civil engineering involved the use of resins for abrasion resistant and non-slip surfaces to heavy duty floors and roads. This was achieved by the use of synthetic anti-skid grits, such as calcined bauxite, set in a resin base. Both epoxy and polyester resins have been used, applied either by trowel or in slurry form by squeegee. Trowelled systems are usually heavily filled mortars with an aggregate resin ratio of the order of 6 1 and as such usually require a priming... 

The thiol-ene type of cure is based on free-radical additions of thiols to unsaturated compounds. The unsaturated compounds are often, though not necessarily, allylic ftmctionalized resins, such as allyl ethers and allylic urethanes and ureas. The thiol-ene systems find application in poly(vinyl chloride) based flooring and in gaskets. 

Resins based on phenol and formaldehyde or a combination of phenol, resorcinol and formaldehyde are used in many glues and adhesives. The resins are used for decorative boards, laminated boards for floors, plywood, water-resistant boards, glass and mineral fibres for insulating, brake and clutch linings, abrasive cloth and paper, grinding wheels and moulds for casting metal and plastic. 

The REZKLAD epoxy-based system consists of a Concrete Primer and Flooring Compound, plus an Expansion Joint Compound and Surface Sealer available for use where necessary. The CLADKOTE Flooring Compound is a modified polyester, resin-based monolithic overlay for concrete. The composite of resins and siliceous reinforcing material cures to a tough, chemical resistant topping. CLADKOTE C utilizes a 100% carbon filler specifically designed for service in hydrofluoric acid and fluoride salts.

Resins are used, for example, to improve the tack of PSA or the green strength of a flooring adhesive. They must be compatible with the polymer and improve the polymer flow characteristics. But generally, a better flow comes along with less cohesion. Derivatives of gum rosins and of abietic acid are commonly used for acrylics, whereas hydrocarbon resins based on petroleum oil derivatives are preferred for tackifying SB emulsion polymers. To retain the solvent-free feature offered by emulsion polymers, resin dispersions or resin melts are used instead of resin solutions. 

These resins, based on synthetic rubber, provide a film when properly plastieized that has high resistance to water, chemicals, and alkalies. Rubber-based resins are exeellent as swimming pool paints, concrete floor finishes, exterior stueeo and asbestos shingle paints, and other coatings requiring a high... 

The main constituents of the SBR HSL based flooring adhesive are the resin-oil blend, surfactant, latex and filler (see guiding formulation 1). Carefully selected resin-oil systems are employed for both cost and property reasons (early wet tack... 

The key parameters to control are formulation water content, clay/latex ratio and resin/latex ratio, depending on the desired adhesive cost structure. Not surprisingly, too much filler or too little resin and/or oil will result in inferior properties. Excess water will result in slower drying, and probably the need for more water sensitive thickeners. Like many other SBR based adhesives, HSL based flooring mastics include in-can and dry-film preservatives as well as an antioxidant package to ensure long-term performance. 

Amino resins are manufactured throughout the industrialized world to provide a wide variety of useful products. Adhesives (qv), representing the largest single market, are used to make plywood, chipboard, and sawdust board. Other types are used to make laminated wood beams, parquet flooring, and for furniture assembly (see Wood-BASED composites and laminates). 

All such resin solutions are based on flammable solvents and are becoming increasingly less acceptable on health and safety grounds. There is therefore increased interest in water-based polymer dispersion floor sealers, but, to date, none offer the same improvement to flooring performance that some of the resin solutions can provide. 

Chlorinated rubber floor paints are probably the most common of the lower-cost floor paints on the market. They produce tough and chemically resistant coatings, but their adhesion to concrete is not always good. They tend to wear off in patches and cannot be considered as a durable floor treatment except under light traffic conditions. However, re-coating is a simple job and floors can easily be repainted over weekend shutdowns, for example. Similar paints based on other resins such as acrylics, vinyls and styrene butadiene are also used. 

Polyurethane mortar flooring systems based on somewhat similar technology to this special polyester system have also been used in chemical plants and have given excellent service. The basic urethane polymer is more elastomeric than either epoxy or polyester resins and, as such, is reported to have excellent thermal properties up...

Phenol was originally recovered during the coking of coal, essentially being a by-product. Eventually, commercial routes were developed based on benzene (from coal or petroleum) for example, sulfonation of benzene to ben-zenesulfonic acid followed by reaction with water to phenol plus regenerated sulfuric acid. Phenol is used to make plastics (phenol-formaldehyde and epoxy resins) and textile fibers (nylon). Phenol is also used in solution as a general disinfectant for cleaning toilets, stables, floors, drains, etc. and is used both internally and externally as a disinfectant for animals.
