BASF Announces MSHA Approval of MEYCO® TSL 865 for Underground Coal Mining Applications


CLEVELAND, OH, October 18, 2010 - The MEYCO Global Underground Construction business of BASF - The Chemical Company - today announced that the U.S.
Mine Safety and Health Administration has approved its MEYCO TSL 865 thin spray-on liner, a one-component polymer powder for spray-application onto soil and rock for supplemental support and protection against weathering.
The MSHA approval expands the acceptable use of MEYCO TSL 865 to the complete range of applications in underground coal mines.

Originally launched in the North American market in August 2009, MEYCO TSL
865 is now approved to seal and strengthen the rib and roof, seal leaky stoppings and overcasts, build maintenance-free block stoppings, and improve the quality of any ventilation control in the mine.

"MEYCO TSL 865 is an innovative thin spray-on liner that was designed for the challenging conditions in underground coal mines," said Haydn Whittam, Segment Specialist - Underground Coal for BASF. "Up until now, there has not been an effective and economical product for controlling the devastating effects of weathering underground. With this recent MSHA approval, MEYCO TSL 865 thin spray-on liner can now be used to its full potential to reduce cost, improve the performance and long-term durability of mines, and improve miner safety."

The product is mixed with water in the spraying nozzle and impacts the substrate as a paste. It sets within five to ten minutes and will progressively increase in tensile strength and bond strength over the next hours, days and weeks. With its excellent bond to most substrates, high elasticity, and high tensile strength, MEYCO TSL 865 thin spray-on liner can substantially improve ground stability.

"MEYCO TSL 865 thin spray-on liner is one of the fastest, simplest and most effective products of its type on the market today," said Whittam. "The beauty of it is that it can be applied, dust free, at a rate that's faster than any known product of its type, and only needs a quarter inch coating to perform very effectively, making it an extremely economical solution."

MEYCO TSL 865 thin spray-on liner is one of many solutions available from BASF's MEYCO Global Underground Construction division.
