SILCOTE-CR can be applied directly over prepared bare metal or over existing paint or other topcoat. Its protective properties stem from its extraordinary adhesion and extremely tight microstructure that resists the passage of vapor and gasses. It is an easy to work with two part coating that can be formulated to very low VOC levels depending on regional and application requirements.
SILCOTE-CR coatings are hard, tough with excellent abrasion, chemical, solvent and stain resistance. They provide outstanding UV and weather protection and can also be used in continuously submerged applications. SILCOTE-CR coatings retain their color and gloss far better than practically any other topcoat in the protective coating industry, including the best of breed epoxies and polyurethanes. SILCOTE-CR can also be formulated with anti-graffiti properties for use on outdoor structures that are subject to vandalism. It is also offered, by special order, in a limited palette of colors and metallic finishes. .
By its high volume solids content of up to 90 percent in combination with its ease of application without the use of thinners, a significant reduction of solvent emissions and waste is achieved. The low VOC polysiloxane coating is fully compliant with the increasingly stringent environmental, health and safety requirements without down grading performance. The polysiloxane hybrid coatings represent a large improvement with respect to health, safety and environment compared with epoxy, epoxy acrylic and polyurethane coatings.
The polymeric structure that contains repeating silicon-oxygen groups in the backbone of the polysiloxane hybrid coating provides the basis for its excellent weathering characteristics. As a consequence, the coating is nominally affected by sunlight, weathering or atmospheric oxidations in contrast with organic-base coatings that eventually degrade under these exposure conditions.
SILCOTE-CR is a 2-part coating supplied as Part-A and Part-B. Part-A is the resin and Part-B is the catalyst that enables the curing and hardening of the resin to develop the ultimate physical properties. The mixing ratio is 6:1 and should be strictly maintained in order to ensure optimal functionality. Eight parts of Par-A should be poured into a plastic or metal container just prior to application. Add one part of Part-B to the Part-A in the container and gently stir the mix till a clear slightly straw colored liquid is obtained.
This ensures that the two parts have thoroughly homogenized. Each gallon of SILCOTE-CR will provide a single coat coverage over approximately 750 to 1000 square feet, at approximately 1.5 mil DFT (0.37 mm dry _lm thickness) depending on the nature of the substrate and method of application. The 'wet edge' or working time of SILCOTE-CR is approximately 2 hours making it very spray process friendly. It is important to mix only enough material that can be comfortably and properly coated during this time window.
SILCOTE-CR can be applied by brush, roller or HVLP sprayer after preparing surface as recommended above. All basic precautions associated with solvent based paints and painting should be followed including proper gear, ventilation, masking o_ areas that will not be coated and preventing air borne debris from invading the area being coated and while the coating is wet. IMPORTANT: The area being coated should be well ventilated and there should be no exposure to open flames or sparks of any kind.
SILCOTE-CR has a 2 to 3 hour working time which gives the applicator more than sufficient time to coat large areas, mix additional batches and rectify coating problems and defects along the way. Full cure requires approximately 8 hours. An overnight cure is highly recommended. At this time the coating will have hardened sufficiently to permit foot traffic and will have developed liquid and stain resistant properties. The chemical integration of the resin matrix will continue over the next 48 to 72 hours at which time SILCOTE-CR will achieve its optimal abrasion , chemical and weather resistant properties.
Tools, equipment and containers used for the SILCOTE-CR application can be thoroughly wiped clean with a basic alcohol based solvent such as isopropyl alcohol (IPA commonly known as 'rubbing alcohol'). Tools and other equipment can and then be washed with soap and water if necessary. Liquiguard's EcoKleanz provides an excellent choice for an effective bio-based cleaning solvent if there is a need to remove and reapply worn or damaged SILCOTE-CR. Overruns and spills can also be remedied with EcoKleanz. SILCOTE-CR cleanup residue should be disposed of in a manner similar to disposing normal oil based paint residue and trash.
