STUDIES ON GLASS-REINFORCED MELAMINE LAMINATES

Various melamine formaldehyde resins have been synthesised by using di fferent mole proportions of melamine and formaldehyde. Different catal ysts such as triethyl amine, diethyl amine, triethanol amine, diethano l amine, and sodium hydroxide have also been used. Glass fabric has be en incorporated in these resins for making composites. Physical, mecha nical, electrical, and other properties have been determined. it has b een observed that composites prepared by using melamine formaldehyde r esins in molar ratios 1:1.75, catalysed with diethyl amine give better properties and finish.
