Weir Minerals, manufacturer of Linatex — a global brand of premium natural rubber — is is partnering with one of the top adhesive producers, Henkel. This includes its team of LOCTITE adhesive, sealant, and coating specialists with the aim of developing a mining, solvent-free adhesive for rubber lining applications with zero-volatile organic compounds (VOCs).
VOCs are carbon-based, organic chemicals that are often used in adhesives, paints, and coatings. They’re subject to strict regulations, with some governments aiming to limit worker exposure while others target large-scale emissions (such as the People’s Republic of China’s recent ban on the production and use of high VOC-containing solvent-based coatings and adhesives in order to improve air quality).
Mining companies also target VOC emissions as part of their sustainability strategies. As a result, and in collaboration with Henkel, Weir Minerals developed the LINATEX LOCTITE – LINA 88 cold-bonding rubber adhesive range as a response to the growing need for safer and more sustainable products.
Complementing the Linatex rubber products, this breakthrough in adhesive technology reflects Weir’s core values of safety, sustainability, and performance.
“We’ve had many customers across the globe approach us to make sure that the products they use on site are safe for their employees working in confined spaces,” said Mark Doyle, global product manager – Linatex Rubber and Hose. “At Weir Minerals we take safety very seriously and looked at several possible solutions. Our team worked closely with the LOCTITE experts and developed an adhesive that is stronger than any other product in the market today with the double benefit of being solvent-free with zero VOCs.”
With new LINATEX LOCTITE- LINA 88products, cutting down the VOC emissions has not meant compromising on performance. Rather, the new, custom-formulated rubber adhesive range sets a new industry benchmark for bond strength by exceeding the current standard by up to four times and is significantly stronger than other products presently used in mining.
“Coincidentally, many mine sites and even regional governments are now starting to mandate that only adhesives with zero VOCs be used on site — we are thrilled to say that we have a product that meets this challenge,” added Doyle.
Safety and sustainability focus was the main driver of the project, explained out Ricardo Garib, Weir Minerals Division president.
“Working with Henkel to develop an adhesive that not only outperforms what is currently in the market, but also delivers environmental and safety benefits is a fantastic result for mine operators and their employees,” Garib said. “Weir Minerals promotes a safe environment for everyone. We consider it a priority for our customers and our own people in our service centres where we line minerals processing equipment with Linatex rubber. With sustainability a key issue within our industry, we are proud to be at the forefront with innovative new products.”
“We are so pleased that our partnership with Weir Minerals has helped bring this new innovation to market,” shared Mark Dorn, senior VP Craftsmen, Construction & Professional, and President Henkel Asia Pacific. “It’s always exciting to pioneer new solutions for our customers that are able to deliver on both innovation and sustainability. Being able to positively impact environmental and occupational safety for those in the mining industry is definitely a rewarding accomplishment for the team.”
The new LINATEX LOCTITE – LINA 88 adhesive range has undergone extensive trials in the APAC region, exceeding customer expectations. Weir Minerals will be specifying the new solvent-free and zero VOCs products for all their Linatex applications around the world.
The entire range is non-flammable and safer to use, easy to transport, and does not require any special handling or storage facilities. It can also be sprayed over the top of rubber lining to provide solid UV protection.
“Delivering this breakthrough innovation to the market is representative of the mission that the LOCTITE business has delivered on for nearly 70 years,” said Eric Saunders, VP, Global Head of Marketing and Strategy – Adhesive Technologies. “It’s about leveraging our expertise, our passion for innovation, and our focus on solving the most difficult challenges to create new value for customers. Having the opportunity to bring this to life in collaboration with another industry leader like Weir Minerals has been extremely satisfying and is a true model for future success in the area of innovation.”
