Unique foundry additives GEKO® LE and ECOSIL® LE prevent emission generation from the outset
Two-tier bentonite solution supports sustainable green sand process with improved total cost of ownership
Visit Clariant at GIFA 2015, Hall 12 Booth C13, June 16-20, Düsseldorf
Munich, June 16, 2015 - Clariant, a world leader in specialty chemicals, introduces GIFA 2015 visitors to Clariant LE Technology, its unique low emission technology enabling foundries to reduce BTEX emissions from green sand systems by up to 80% and produce highest quality castings at optimum productivity.
Launched after four years' extensive field testing, casting additives GEKO® LE and ECOSIL® LE - Clariant's two-tiered bentonite solution - are proven to provide unmatched benefits for foundries looking to improve the ecological footprint of green sand molding, in line with increasing regulatory emission requirements and awareness regarding health and the environment. The additives, which are important for mold production and the subsquent separation of casting and mold material, also address demands for higher productivity, precision molds and thinner walled castings from the automotive industry. Over 50% of European-produced green sand castings were used for road vehicle production in 2013.
The benefits of Clariant LE Technology build on the unrivalled precision, smooth processability and surface finish, and easy shake out associated with Clariant's industry-trusted ECOSIL® lustrous carbon former ranges and GEKO® bentonite boosters for green sand castings.
The LE variants are unique in preventing BTEX emission generation in green sand systems from the outset. This benefit for both the environment and foundry workers is achieved through a patented mix of high-quality bentonites, graphite, dispersants and optionally coal. They are highly efficient, requiring significantly lower amounts of binding agents, lustrous carbon producers and other additives.
As a result, the performance and productivity-related advantages are enhanced by environmental advantages such as excellent recyclability of used sands and less waste generation, to create an optimized total cost of ownership for foundries. Importantly, the technology can be incorporated without investment in existing green sand systems.
Eric Bonin, Laboratory Manager of PSA (Peugeot Citroën), comments:
The concrete benefits in using LE Technology in PSA are:
- The reduction of the BTEX emissions
- The improvement of the molding and mold release accuracy
- The reduction of the Premix consumption
Adding to the range's sustainability value, customers choosing any GEKO® and ECOSIL® products have the assurance of Clariant's responsible mining approach, and long-term supply continuity guaranteed by Clariant's investment in its own bentonite mines and production facilities located close to customers worldwide.
The combination of benefits qualifies GEKO LE and ECOSIL LE as EcoTain® products within the Clariant portfolio. Clariant assigns its flagship EcoTain label to those products showing best-in-class sustainability and performance excellence, providing a clear indicator to customers of their added value.
Stefan Dick, Head of Commercial Activities EMEA, Clariant BU Functional Minerals, comments: "The package of benefits created by GEKO LE and ECOSIL LE helps foundries to be responsible neighbours and achieve their environmental targets, without compromising performance requirements. Our unique technology can make a positive contribution to the foundry industry's sustainability goals."
Visit Clariant at GIFA 2015 to find out more about ECOSIL LE and GEKO LE in Hall 12 Booth C13 from June 16-20, 2015.

The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner." AND ENTERS UPON HIS PARENTAL RELATIONS TO LITTLE PETE SKIDMORE. "Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
