Once<strong>the</strong> domain of bearded men wearing Birkens<strong>to</strong>ck sandals,<strong>the</strong>y have now arrived in corporate boardrooms all over<strong>the</strong> world. Sustainability has become a buzz word in <strong>the</strong>business community. What exactly does sustainabilitymean <strong>to</strong> you, though?That is <strong>the</strong> question that Henkel Product Manager ErikEdelmann and his team asked <strong>the</strong>ir industrial cus<strong>to</strong>mers.“For most cus<strong>to</strong>mers it is ra<strong>the</strong>r difficult <strong>to</strong> clearly definesustainability. The term generally encompasses energyand climate, materials and waste, water consumption,health and safety, as well as social progress. <strong>How</strong>ever, <strong>the</strong>primary focus is clearly on occ<strong>up</strong>ational health and safetyand environmental responsibility,” says Edelmann.A clean sheetThis was not an entirely new challenge <strong>for</strong> Henkel, as <strong>the</strong>company has always placed great importance on nonhazardoussubstances and minimal eco-<strong>to</strong>xicity in <strong>the</strong>more than one hundred years of its his<strong>to</strong>ry. With <strong>the</strong> newthreadlockers <strong>Loctite</strong> ® 2400 and <strong>Loctite</strong> ® 2700, Henkel hasbroken new ground in occ<strong>up</strong>ational health and safety. Themedium strength threadlockers <strong>Loctite</strong> ® 2400 and <strong>the</strong> highstrength threadlocker <strong>Loctite</strong> ® 2700 are a leap <strong>for</strong>ward,because <strong>the</strong>y both have a “white” MSDS (Material SafetyData Sheet).Never sacrifice per<strong>for</strong>manceAs usual, <strong>the</strong> Henkel specialists in <strong>the</strong> Dublin Technologycentre were working <strong>to</strong>ge<strong>the</strong>r very closely with <strong>the</strong>ircus<strong>to</strong>mers during <strong>the</strong> development process. “In <strong>the</strong> caseof <strong>Loctite</strong> ® 2400 and <strong>Loctite</strong> ® 2700, we were collaboratingwith two large cus<strong>to</strong>mers in France,” says Edelmann. Hisprofessional background is in chemical engineering, atraining which greatly facilitated <strong>the</strong> communication withleading developer David Condron in Dublin. “The cus<strong>to</strong>mers<strong>to</strong>ok a very cautious approach and insisted that not even<strong>the</strong> decomposition products should be hazardous,” saysCondron.Not willing <strong>to</strong> sacrifice per<strong>for</strong>mance, Condron and hiscolleagues worked <strong>for</strong> more than a year on <strong>the</strong> projectand finally made it happen: <strong>the</strong>y developed products thatretained <strong>the</strong> cus<strong>to</strong>mary high <strong>Loctite</strong> ® per<strong>for</strong>mance with a“white” health and safety bill.“We were lucky <strong>to</strong> have <strong>the</strong> chance <strong>to</strong> cooperate withhighly sophisticated and demanding cus<strong>to</strong>mers,” saysEdelmann.“A white MSDS means that according <strong>to</strong> <strong>the</strong> <strong>to</strong>ughregulations of (EC) No. 1907/2006 - ISO 11014-1 boththreadlockers do not carry any hazard symbols, risk or safetyphrases. In addition, <strong>the</strong>y do not contain any declarableCMRs (Carcinogenic, Mutagenic and Reproductive <strong>to</strong>xins),”explains Edelmann and continues: “You will be surprised<strong>to</strong> see that your ordinary dishwashing agent or all- purposecleaner carries more hazard symbols than <strong>the</strong>se industrialproducts.”RD&E InsightsThe evolution of new adhesivesDavid CondronSenior Chemist, Product Development Europe,Dublin, Irelandat work | no. 2/09
