GICALShip BuildingThe WIWA DUOMIX has enjoyedworld-wide success in theship building industry for twoand three component applications,such as block, ballasttank, outer hull and deck coatings.Railcar IndustrySolvent-free and water-basedcoating materials have prevailedin respect to coatings forrailcars and other largevehicles. Wide range of availableperformance ratings Designed according toindividual requirements Shorter curing times Reduction in materialand labor costs Environmentally friendlyPipe and Tank CoatingsThe WIWA DUOMOIX systemshave proven their value inthese especially demandingfields of coating application.Pipeline MaintenanceDue to its robust nature, theWIWA DUOMIX can be effectivelyused in remote terrainenvironments and has provensuccessful in various pipelinemaintenance projects.Here, an icebreaker is beingsprayed with a special coatingmaterial (potlife: 5 minutes,spraying temperature: 55°C) usinga WIWA DUOMIX 333 with heatedhoses.Many of today’s tank coatings callfor dual component coating materialswith an extremely short potlife(ie. 30 seconds).1

WIWA DUOMIX High-PerformanceSpraying Equipment – The reliablesystem for the large variety ofplural component coating materialsADVANTAGES OF THE DUYears of experience, a sophisticatedconcept and ahigh-caliber, robust designare typical traits of WIWAquality.WIWA DUOMIX –probably the only dual componentsystem world-wide whichcombines the flexibility of avariable mixing ratio and thesecurity of a fixed ratiosystem, in addition to beingable to process three componentapplications.Requiring little work at all,the center hardener pump canbe exchanged to achievealmost any mixing ratio between1:1 and 8:1 (incl. decimalvalues, such as 5,6:1).1:18:1The time-consuming literingand adjusting necessary forother dual componentsystems is eliminated, aswell as the unintentionalalteration of the mixingratio’s setting.Output per cycleup to 700 ccmPressure ratio up to 85:1Principles of the DUOMIX SystemMixing ratio from 1:1 to 8:11 14 1 4MixerMaterial Containerwith Feed PumpHigh-PressurePumpFlush-PumpThe ApplicationDetermines theDesign.The high-pressure pump ensuresthat the exact dosage of eachcoating material component (baseand hardener) is dispensed intothe mixing block and then led tothe spraying gun.When preparing to flush thesystem, mixed material still locatedin the spraying hoses can stillbe applied due to the high-pressureratio of WIWA’s flush pumps.2

OMIX CONCEPTIf desired, every WIWA DUOMIXsystem can be delivered with ameasurement device to show theflow rate of each component or tomonitor the mixing ratio and, ifrequired, to print a record of theresults.Here, pipes were sprayed with apolyurethane coating material(potlife: 30 seconds, sprayingtemperature: 55°C) using a WIWADUOMIX 300. In use world-wide forthe processing of highviscosity,solvent-freetwo and three componentmaterials. Whenworking with materialshaving an extremelyshort potlife (i.e.30 seconds), the WIWADUOMIX best exhibitsits strengths.In the area of pipeline maintenance,a potlife within the rangeof 5 – 30 seconds is common. The main fields ofapplication are themarine and offshore oilindustries, tank andcontainer construction,pipe and pipelinecoatings, coatings forrailcars and other largevehicles, protectionand sanitation of steelstructures, and otherlarge surface areacoatings, such as silos,cooling towers andsewage plants. A wide range of performanceratings forall high-, middle- andlow-viscosity dualcomponent coatings isavailable. Even at low ambienttemperatures, perfectcoating results areassured through theuse of various heatingsystems. As a result of itsspecial conception, theWIWA DUOMIX DualComponent System canalso be used in applicationsrequiring threecomponents. Due to the modulardesign of the WIWADUOMIX, a nearlyboundless variety ofsolutions is achievedand each system isconfigured reflectingthe individual requirementsof the customer.3

ON …Air Motor1The patented air motor isequipped with a uniquede-icing system and robustmaintenance unit. Itspiston rod is guided bytwo axles which lead intothe upper and lower housings.This ensures tilt-freeoperation of the threematerial pumps which areconnected directly to thesame piston plate, andreduces wear and tear onthe packings and pistonrod.Material Pump Combination2345By simply exchanging thecenter hardener pump, anew mixing ratio can beachieved quickly and effectively.Should new applicationsrequire different performanceratings, these canalso be achieved byexchanging the materialpumps.A closed lubrication chamberseparates the air motorfrom the material pumps.The lubricant preventspaint from crusting ontothe piston rod and protectsthe packings.All material pumps areequipped with fixed,spring supported, selfadjustingpackings.Pressure and MeteringMonitorTo avoid any mixing ratioerrors, the pressures of bothcomponents are monitored bymeans of two contact pressuregauges.Should WIWA’s recommendedtolerance settings for themaximum and/or minimumpressure be surpassed, thesystem shuts down automatically.WIWA’s standard incorporationof rupture discs into thesystem prevents operationabove the maximum allowableworking pressure and possibledamage as a result.Simple operation by means oflarge, practical, easy to findcontrol switches. The pressurelevels can be easily read onthe large pressure gauges.Since the entire system, includingthe pressure andmetering monitor, is operatedpneumatically, the WIWA DUO-MIX is explosion-proof (unlessnon-explosion-proof devices,such as heating elements orother electrical componentsare added to the unit).Technical Training forInternational Personnel5
