Mat

25、erials and Manufacture5.1 ResinThe resin used shall be a commercial-grade, corrosion-resistant thermoset that has either been evaluated in alaminate by test in accordance with 11.3 or that has been determined by previous documented service to be acceptable for theservice conditions. Where service co

26、nditions have not been evaluated, a suitable resin also may be selected by agreement betweenfabricator and purchaser.5.1.1 The resin shall contain no pigment, dyes, colorants, or filler, except as follows:5.1.1.1 A thixotropic agent that does not interfere with visual inspection of laminate quality,

27、 or with the required corrosionresistance of the laminate, may be added for viscosity control.NOTE 3The addition of a thixotropic agent may reduce the resistance of many resin systems to certain corrosive chemical environments. It is theresponsibility of the fabricator, using a thixotropic agent in

28、the resin required for 7.1.1 and 7.1.2, to ascertain its compatibility with the corrosiveenvironment when this has been reported to him by the purchaser.5.1.1.2 Resin pastes used to fill crevices before overlay shall not be subject to the limitations of 5.1.1.5.1.1.3 Resin may contain pigment, dyes,

29、 or colorants when agreed upon between fabricator and purchaser.NOTE 4The addition of pigment, dyes, or colorants may interfere with visual inspection of laminate quality.5.1.1.4 Ultraviolet absorbers may be added to the exterior surface for improved weather resistance, if agreed upon betweenfabrica

30、tor and purchaser.5.1.1.5 Antimony compounds or other fire-retardant agents may be added to halogenated resins for improved fire resistance, ifagreed upon between fabricator and purchaser.NOTE 5Because the addition of fire-retardant agents may interfere with visual inspection of laminate quality, th

31、ey should not be used in the innersurface (7.1.1) or interior layer (7.1.2) unless their functional advantages would outweigh the loss of visual inspection.5.2 Reinforcement:4 Available from American National Standards Institute (ANSI), 25 W. 43rd St., 4th Floor, New York, NY 10036, http:/www.ansi.o
