Strata Bond
This version will, upon machine mixing, instantly form a smooth pumpable gel which is thixotropic, i.e. it exhibits shear thinning. This enables the material to flow easily under the pressure/force eg. through the injection machine. When the pressure/pumping stops, the material reverts to the gel and stops flowing thereby preventing the material from running out of cracks or adjacent injection ports.
Strata Bond is a two component, 1:1 by volume, fire resistant injection system based on urea silicate technology. Using a two-component injection pump coupled with a static in-line mixer head it is designed to rapidly stabilise strata and coal by imparting structural strength and flexibility. Strata Bond can be used in wet environments where it exhibits good adhesion to wet surfaces, but will not absorb water.
In addition to being fire resistant owing to its unique silicate chemistry, the maximum exotherm reached during crosslinking is well under the maximum 150°C allowed as specified by the NSW Government Trade and Investment Mine Safety Guideline MDG 3608 August 2012, Appendix D1-TM003.
