Safety of Tekon® Protective Coatings |

Monday, 31 December 2007 |
The protective coating element of Tekon® products consists of organic silicon compounds (chemicals combining carbon and silicon atoms, or “silanes”) dissolved in appropriate organic solvents. The “silane” compound is chemically reactive with both itself, and also the surface to be coated. The organic solvents serve to dilute the active silane ingredient to the right concentration, and provides a way of applying the material to a surface and achieve the correct protective coating thickness.
The liquid coating itself is a mild irritant, and typical of most organic solvents. The active silane ingredient may also be classified as a mild irritant, and should not be splashed in the eyes, inhaled in any great quantity or have prolonged skin contact. When the solution is applied to a surface the organic solvents evaporate away and the coating remains, gradually curing (within 30 to 60 seconds) with exposure to humidity. The curing process releases very small amounts of isopropyl and ethyl alcohols which also evaporate away. The resulting coating consists of a network of carbon and silicon atoms tightly linked together. The cured coating is insoluble, free of volatile residues, and no longer contains irritants of any variety. The surface chemistry of the coating resembles paraffin wax (which also accounts for its non-wet ability). Based on its chemistry, insolubility and durability, coatings of Tekon® can be considered to be chemically inert and entirely non-toxic.
Tekon® treated countertops, sinks and appliances are entirely safe for food preparation.
