Amino resins are vital cross linkers used in paint industries in industrial stoving finishes alongwith alkyds, epoxies, acrylics, polyester as well as in catalyzed cured lacquers, with indigenous production and growth in usage the need has been felt for preparation of this standard. Water reducible amino resins are also available for use in environmental friendly paint system. The composition of the Committee responsible for the formulation of this standard is given in Annex B. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result ofatest oranalysis, shall berounded off inaccordance with IS 2:1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. IS 15365:2003 Indian Standard AMINO RESINS FOR PAINTS — SPECIFICATION 1SCOPE on availability and major usage in surface coating industry: This standard prescribes the requirements and methods of sampling and test for amino resins used in paint a) n-Butylated urea formaldehyde resins, and industry. b) n-Butylated melamine formaldehyde resins. 2 REFERENCES 4.2 The above two major classes of amino resins may be further classified based on reactivity of resin which Tile following standards contain provisions which is in turn, based on degree of etherification through reference in this text, constitute provisions of (butylation) or mineral turpentine oil tolerance, as this standard.
