AUTOMATIC APPLICATIONThe fastest PROTEGOL ® application rates can be achievedby means of the automatic spray ring. This method hasproven to be the most productive and reliable methodand is not only suited for short distances such as bellhole rehabilitation, but also for the coating of the entirepipeline – either in or over the ditch and even when thepipeline is in service.TIB Chemicals has been actively involved within theresearch and development phase of the first automaticspray ring for application of PROTEGOL ® in the field.PROTEGOL ® two-component liquid coatings are thepreferred choice, when application in the field isrequired. Pioneered in the early 1990s as the firsttwo-component polyurethane coating to be selectedfor the external protection of field joints of pipespre-coated in the factory with multi-layer PE and PPsystems, PROTEGOL ® continues setting the standardfor field joint coating utilising MCL (Multi ComponentLiquid) systems. It remains the most widely recognisedliquid coating system for field joint application today.MANUAL APPLICATIONManual spraying involves airless and air-assisted sprayingmethods. With the plural component airless hot spraymachine, production rates are increased. High coatingthicknesses of PROTEGOL ® coating systems can beachieved in just one single pass resulting in ahomogenous and pinhole free coating.Another PROTEGOL ® method of application consistsof manual application using a brush, spatula or rollerand can be utilised to stripe-coat edges and welds or totouch up damaged areas.PROTEGOL ® coatings supplied in cartridges can beapplied efficiently using an air-assisted spray gun.This is preferably used on smaller areas and wherelimited working space could make application work witha plural component airless system difficult.| 16
