8 1. PHELIC RESIS (VI) Properties of Phenolics Have good chemical and thermal resistance, dielectric streth, and dimensional stability. Most phenolics contain fillers or reinforcements General-grade phenolics are filled with mica, clay, mineral flour, cellulose, and chopped fabric Eineeri-grade phenolics are reinforced with glass or organic fibers, elastomers, graphite Products made with these resins are inherently low in flammability, are creep resistant, and have low moisture absorption (7) School of Chemistry & Chemical Eineeri

13 2. AMI RESIS (IV) Properties of Amino Resins A distinct advantage of the amino resins over the phenolics is clearer and colorless They are harder than phenolics but have somewhat lower impact streth and resistance to heat and moisture The melamine resins have better hardness, heat resistance, and moisture resistance than the ureas Applications of Amino resins Adhesives (better performance than the phenolic resin) Ex., the manufacture of plywood and fiberboard Melamine resins are used to produce colored dinnerware and dinnerware with decorative patterns. Amino resins also find extensive as automotive parts; the cheaper ureas are used as primers while the melamines are used as topcoats (12) School of Chemistry & Chemical Eineeri
