Floor Sealer

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. 

Polyvinyl acetate (PVA), acrylic and other polymer dispersions have been widely used as anti-dust treatments for concrete floors for many years. In general, the polymer dispersions have been similar to those used in the manufacture of emulsion paints, and until recently have tended to be based on dispersions of relatively large polymer particles (particle size 0.15-0.25 x 10 m). Dispersions are now becoming available which offer superior performance as floor sealers. The chemical and water resistance of the various polymer dispersions which have been used in the past vary considerably from the PVA types, which are rapidly softened and eventually washed out by water, to acrylic and SBR types which exhibit excellent resistance to a wide range of chemicals. Water-based sealers are gaining wider acceptance because of... 

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.

Floor sealers are clear, unpigmented coatings rqiplied to porous substrates like conoete and tiles to seal the surface and protect against soiling. Reladvely hard (Tg 50-90°Q, solvent and water resistant, thermoplastic compositions, similar to those for OEM coatings, are used.

Floor sealer n. Composition of resins, with or without oils, in a solvent designed to penetrate the wood rather than produce a surface finish.

The uniqueness of methyl methacrylate as a plastic component accounts for its industrial use in this capacity, and it far exceeds the combined volume of all of the other methacrylates. In addition to plastics, the various methacrylate polymers also find appHcation in sizable markets as diverse as lubricating oil additives, surface coatings (qv), impregnates, adhesives (qv), binders, sealers (see Sealants), and floor poHshes. It is impossible to segregate the total methacrylate polymer market because many of the polymers produced are copolymers with acrylates and other monomers. The total 1991 production capacity of methyl methacrylate in the United States was estimated at 585,000 t/yr. The worldwide production in 1991 was estimated at about 1,785,000 t/yr (3). 

Formulas for representative floor poHshes are Hsted in References 3, 12, 13, and 25. An aqueous formula may contain 0—12 wt % polymer, 0—12 wt % resin, 0—6 wt % wax, 0.3—1.5 wt % tris(butoxyethyl)phosphate, 1—6 wt % glycol ether, and 0—1 wt % zinc, with water filling the rest. Water-clear floor finishes contain Htfle or no wax, whereas buffable products contain relatively large amounts of wax. Sealers contain Htfle wax and relatively large amounts of emulsion polymers (28). For industrial use, sealers are appHed to porous substrates to fiH the pores and prevent poHshes that are used as topcoats from soaking into the floor. 

Resin solution penetrating sealers are now available which, for very large warehouse floors, are comparable in applied costs with the concrete surface hardeners and are now being increasingly specified. Experience indicates that certain acrylic resin solutions are proving more durable and offer better protection to chemical and oil spillage than concrete surface hardeners. Acrylic resin solution sealers can markedly improve the abrasion resistance of concrete floors and have rescued a number of poor-quality floors. 

Sheet vinyl is best installed by professionals, whereas tiles can be laid by amateurs if instructions are followed carefully. Sheet flooring is usually considered more attractive and easier to maintain. It has few seams to open up in time and become dirt catchers or entrance points for moisture. In some materials, seams can be welded by heat, thus forming a permanent seal. Others will in time require additional sealer. Tiles, on the other hand, can be laid with less waste and also have the advantage of being replaceable if damaged. Whichever type is chosen, a supply of extra tiles or a few scraps of sheet flooring should be kept for possible future repairs. 

After some deliberation, sheet flooring was chosen rather than tile. Commercial grade vinyl was used in a color which harmonized with the laboratory furniture. The flooring was installed before any furniture arrived. While this called for more material, labor cost was much less. A sealer was applied to all seams. Although it stood up quite well, flooring with welded seams, not mentioned by either engineer or contractor, would no doubt have been more desirable. 

Toluene diisocyanate is commonly produced as a mixture of the 2,4- and 2,6-iso-niers, that is used as a monomer in the preparation of polyurethane foams, elastomers and coatings, as a cross-linking agent for nylon-6, and as a hardener in polyurethane adhesives and finishes. Polyurethane elastomers made from toluene diisocyanates are used in coated fabrics and clay-pipe seals. Polyurethane coatings made from toluene diisocyanates are used in floor finishes, wood finishes and sealers, and in coatings for aircraft, tank trucks, truck trailers and truck fleets (United States National Library of Medicine, 1997).

These storage structures meet all pertinent requirements of the Resource Conservation and Recovery Act (RCRA). Each building has a concrete foundation and catch basin, a 1,000 psi rolled asphaltic concrete floor with sealer applied and each wood frame, steel-sided building encloses the entire foundation area. These buildings are secured with fences which will be posted, locked and Inspected regularly by MDNR personnel. Thus, safe, secure, temporary storage Is assured until a permanent disposal method can be planned and Implemented.

Use as a base coat sealer on porous, resilient flooring surfaces. Polishes applied over AA-417-S1 will not soak into the floor surface and therefore build gloss with fewer coats. The sealer is not affected by ordinary stripping solutions. This allows polish coats to be removed while leaving the sealer intact. Up to two coats per application are suggested and may be applied with 25-40 min. drying time depending on solids and... 

Developed for use as an anti-skid additive to floor paint or sealers, Clear-Grip is a durable, micronized polymeric aggregate that will not soften under normal heat exposure.
