✦ Synopsis
resistant plastic coatings have been developed especially for the pulp and paper industry for the protection and maintenance of chemical processing equipment.
Described as an inexpensive, easily applied, high solids synthetic paint, the coating is said to be unsurpassed in protecting metals, wood and ceramic surfaces against chemical attack by corrosive fumes, condensates, spillage, etc., and to dry quickly by solvent evaporation to an adhesive, hardwearing, flexible, glossy coating without the necessity of priming the surface being coated. Manufacturer states that the compounding ingredients have been selectively determined by laboratory research to provide the utmost adhesion and resistance to chemical attack without the use of conventional priming and intermediate coating procedure to achieve a corrosion resistant film for general maintenance purposes. Further to cut the cost of corrosion protection, formulations have exceptionally high solids content which result in a coating of substantial body and hiding power with coverage of 350 to 450 sq. ft. of area per gallon per coat when applied by brushing directly from container. The plastic coatings are said to be unaffected by all alkalies as well as by their salts and by most mineral acids, also to be inert to alcohols, soaps, water, oxidants, food and fruit acids, oils, aliphatic hydrocarbons, gasoline (low octane) and many other corrosive reagents. Moisture vapor transmission rate for films of 0.002 in. thickness is given as less than 2.0 grams per 100 sq. in. of area for 24 hr. at 100 per cent relative humidity.
Non-oxidizing coatings are recommended by manufacturer for services to 180 F., and to maintain flexibility over a wide rangeof temperatures. CycLon coatings are made by Poly-Cyclo Products Co.
