《塑料技术手册 涂层·浇注成型·反应注射成型·旋转成型（2 影印版）》： Thixotropy is a property of a plastic that is a gel at rest but liquefies upon agitation.and loses viscosity under stress.Liquids containing suspended solids are likely to be thixotropic.They have both high static shcar strength and low dynamic shear strength.For example， these materials have the capability to bc applicd on a vertical wall and through quick curing action remain in position during curing. All dispersion coatings must bc properly baked or fused in order to coalesce the tiny dispersed resin particles into a continuous， tough， and flexible film.Depending on formulation and dwell time， the required fusing tempcratures （based on actual metal temperatures） vary from 300°F to 525°F （149℃ to 275℃）.The pref’crred cycle for sheet bakes is 10 minutes in the 350°F to 525°F （177℃ to 275℃） range.In moving—web application （coil or strip coating）， a cure cycle of 60 seconds or less at about 525°F yields good results.These cited examples， of course， are for vinyl chloride dispersion systems.Fluorinated dispersion coatings require substantially higher temperatures （approximately 550°F to 600°F （288℃ to 316℃）） for proper film formation. Since fusion of the dispersed particles is the major objective in the curing procedure， the baking cycle for a given application depends on how quickly the wet film reachcs fusing tempcraturc.When this critical temperature is reached， the tiny， partially solvated particles quickly coalesce into a homogeneous coating.Problems of thermal degradation will occur if the coating is subjectcd to tempcratures in excess of 500°F （260℃） for vinyl chloride dispersion； degradation will occur at tcmperatures in excess of 600°F （316℃） for vinyl or vinylidene fluoride dispersions for prolonged periods. ……
