Concrete coatings chlorinated rubber

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. 

Chlorinated rubber See Section 12.3.2. This is used for decoration but also provides a relatively impermeable coating. Its best use is for concrete surfaces that have to be kept clean by regular washing. 

Figure 1 indicates a typical nitroglycerin facility "inside out" wood frame construction at a concrete floor slab. Note that the exterior cant strip, the lead conductive floor cant and the wood cap are all sloped to discourage product build-up and facilitate cleaning. This assembly also indicates spray-on foam insulation as an optional construction item. At Radford AAP this is a safety approved insulation system. The insulation at Radford AAP received a chlorinated rubber paint coating for weathering.

Organic coatings may vary from very dense to rather open for water vapour. A dense coating (ideally without flaws), based on epoxy, polyurethane or chlorinated rubber polymers, may block ingress of aggressive species. Nevertheless, the presence of such a layer strongly hinders the evaporation of the moisture that is present in the concrete at the time of treatment. This situation can lead to loss of adhesion to the concrete and thus to a loss of effectiveness of the coating. 

Uses. On account of their high water resistance, chlorinated rubber paints are used for underwater coatings on steel and concrete (e.g., water storage vessels, swimming pools, sewage systems, harbor installations, and docks). The chemical resistance is...

These single-pack protective coatings, based on chlorinated rubber, are fast drying and give very good water, chemical and corrosion resistance. They are suitable for coating steel and concrete surfaces and are recommended for applications subject to chemically laden atmospheres or in a coastal environment and can be applied by spray, roller or brush. Typical uses include bridges, chemical plants, marine structures, ships and structural steelwork. 

The common coating systems for concrete are listed in Table 14.19.1.2. Synflietic resins (e.g., chlorinated rubber, styrene resins, acrylic resins) contain normally 40-60% solvents and form a thin film. Several coats must be applied. Reactive resins may require little or no solvent. 

Quite often curing compounds are applied to fresh concrete as soon as practical after the forms have been removed. These are liquid membranes based on waxes, resins, chlorinated rubber, or other film formers, usually in a solvent. Pretesting is necessary to determine whether or not they will interfere with the coating to be applied. 

Laser ablation technology for industrial applications has first come to prominence in 1965. For example, chlorinated rubber (CR) coatings were removed from concrete surfaces using a 60 W high power laser diode [59]. The ash particles were investigated by optical microscopy, image analysis, DTA/DTG, ESEM and EDX techniques. 

This consists of applying a thin coating on the concrete surface which acts as a barrier to the environment and does not allow penetration of corrosion species. Epoxy coatings offer excellent adhesion and corrosion resistance in harsh environments. The most commonly used coatings include acrylic, chlorinated rubber and polyurethane coating. The suitability of commonly used coatings for different environments is given in Table 12.3.
