dc.description.abstractIn foundry, metal casting can be done with various methods. One of the most important methods preferred around the world is sand casting. Ester curable alkaline phenolic resins have produced to make sand molds by No-bake systems. They must have specific properties to make sand casting efficient and reliable. Production of these resins depends on some fossil raw-materials like phenol. To investigate more sustainable and green resin synthesis method, lots experiment have been done by substitution of phenol with renewable alternative phenolic materials like resorcinol, lignosulphonates and tannic acid and its derivatives. Different properties of resins were produced with competitive performance with the market product, ÇKE Alfanol A 72 No-Bake Resin. Without loss of performance, calcium lignosulfonate was used in polymer synthesis at the rate of 15% instead of phenol. On the other hand, the reaction in which lignin and resorcinol were combined instead of phenol by reducing it by 25% gave better results in terms of mechanical and thermal properties. Thermal properties were investigated for resorcinol and lignin modified resins by using TGA-DSC and mechanical performance of cured sand core sample were tested by Simpson Sand Strength Testing Machine as compression strength as N/cm2.. After laboratory testing casting performance of new resins are compared with two different companies’ resins in steal casting demo. Experimental results were matched with casting trail and no defect was detected. © 2021 Polish Academy of Sciences. All rights reserved.
