European Coatings Show Preview December 2014 www european coatings show com 13 Focus Supporting end of life recycling Regulations will remain highly influential in the future Dr Jean Paul Lecomte Global Technical Leader for Building Material Protection at Dow Corning Belgium devotes most of his time to studying the hydrophobicity of build ings One of the reasons is that the biocide directive has been tightened up  Construction chemistry is a wide field Which ap plication and aspect are you most interested in Dr Jean Paul Lecomte Con struction chemicals are enabling materials Amongst other applications they are used to improve the proper ties of construction materials or to enable their use in more demanding applications It will be interesting to see over the course of the next 20 years how important con struction chemicals will be in helping key societal aims concerning improved sus tainability of the construc tion industry to be attained Improving the life cycle of construction materials and then of buildings will be achieved by extending their durability on one hand and supporting recycling or mak ing it easier for them to be recycled at the end of their useful life on the other The list of construction chemi cals that could play a role ranges from improved bind ers more efficient super plasticizers for making stiffer concrete durable protective coatings water repellents film forming coatings for reducing corrosion or water induced damage improved wood protection to enable greater use of local species and enhanced treatment to make wood more fire resist ant to promote its use in more applications Hope fully construction chemistry in general and construction chemicals in particular are viewed as an exciting field by young scientists because there are many problems that still need innovative solutions  A number of legislative circumstances influence developments what comes next where technological changes are concerned Lecomte There is no doubt that the regulatory environ ment is influencing new product development It can be difficult to keep up with all the changes In this context the European Federation of Construction Chemicals EFCC is a good source of information on emerging regulations for its members The regulations concerning VOCs and bioc ides are two driving forces that are heavily influencing research and development and product re formulation The changeover from sol ventborne to waterborne formulations is already well advanced The use of emul sions no matter which active material is being emulsified is already standard practice and evolved out of the de livery system developed for specific active materials The next step will be to de velop inherently low VOC active materials This will affect formulations ranging from paints coatings water repellents damp proofing solutions and sealants as well as or applications which are still considered minor contributors to overall VOC emissions Another of the challenges ahead will be to reduce bio cide content in ready to use formulations such as wood treatments or coatings with out diminishing resistance to algae or fungal growth The right water repellents whether as post treatment products or integrated into the products as water repel lents can help to control moisture movement in treat ed material and boost the rate of drying This is likely to be one of the solutions used to optimize biocide content in formulations xz Dr Jean Paul Lecomte Dow Corning Europe www effects for coatings com Xirallic NXT Panthera Silver Delivering amazing clarity and depth Xirallic NXT Panthera Silver exemplifies brilliance and purity This new effect pigment turns the surface into a masterpiece of dancing light and radiant shimmer The NeXT Generation of Xirallic Effect Pigments from Merck Meet the Merck experts ECS I Hall 1 I Booth 1 614 Source Mike Fotografie Fotolia
