Planning guideCeram coatingCeram C1 - Technical dataDescriptionCeram C1 is a cold-hardening, solvent-free composite material basedon two components with selected reinforcement fillers and extenders.CompositionPolymer/aluminium oxide composite material made of a base compoundand reinforcement.Base compound: A modified polymer made up of two parts with analiphatic hardening agent.Reinforcement: A mixture (protected by proprietary rights) made upof aluminium oxide and extenders.This mixture has excellent abrasion resistance and can be appliedvery easily.Properties• The completely hardened Ceram C1 coating has a glossy finish, nopores and is easy to clean, mechanically very resistant, abrasionproofand has excellent adhesive properties.• Ceram C1 hardens without shrinking and is resistant to a largenumber of chemicals, oils, greases, solvents, diluted organic and inorganicacids and bases and saline solutions.• Ceram C1 reduces friction and improves flow and efficiency.• Excellent corrosion protection.Technical dataHardness Buchholz 115Density / mixture ASTM D 792 1.4 g/cm 3Shrinkage during hardening ASTM D 2566 0.002 mm/cmTensile shear resistance ASTM D 1002 13.8 N/mm 2Tensile strength / ultimate ASTM D 638 26.2 N/mm 2strainCompressive strength ASTM D 695 60 N/mm 2Bending strength ASTM D 790 55.2 N/mm 2Adhesive strength / steel ISO 4624 13.8 N/mm 2Impact resistance / strength ASTM D 256 11 J/mCoefficient of linear expansionASTM D 696 34.5 x 10 -61 1/KElectrical resistance ASTM D 257 8 Ohm cmThermal conductivity ASTM C 177 0.7 W/m x KPorosity test Test voltage 5 V/m layerthicknessTemperature resistance, dry ASTM D 648 140 °CTemperature resistance, wet ASTM D 648 60 °CResistance tableFluidFactorAcidsSulphuric acid (10%) 2Sulphuric acid (20%) 3Hydrochloric acid (5%) 1Hydrochloric acid (10%) 2Hydrochloric acid (20%) 3Nitric acid (5%) 1Nitric acid (10%) 3Phosphoric acid (5%) 1Phosphoric acid (20%) 3Bases and bleachesSodium hydroxide (10%) 1Sodium hydroxide (50%) 1Ammonia (5%) 2Ammonium hydroxide (28%) 1Potassium hydroxide (10%) 1Potassium hydroxide (50%) 1Fixing salt (6%) 1Soap solution (5%) 1Cement mortar / concrete 1Other compoundsIsopropanol 1Kerosene 1Naphtha 1Salt water 1Sewage 1Toluene 1Xylene 1Bunker C 1Diesel oil 1Tested at 20 °C.
