The material is formulated to produce a high build, material which can be applied by standard spraying techniques. Technical Support Parchem offers a comprehensive range of high performance, high quality construction products. In addition, Parchem offers a technical support service to specifiers, end-users and contractors, as well as on-site technical support. INDEX 30 Technical Data Sheet Design Criteria Guncrete E is designed for vertical, overhead or horizontal applications. It can be applied in sections from 10 mm up to 150 mm depending on substrate geometry. The material should not be applied at less than 10 mm thickness. Specification Clauses Steel reinforcement primer The steel reinforcement primer shall be Nitoprime Zincrich, a single component zinc-rich epoxy resin. The primer shall be an ‘active’ type, capable of avoiding the generation of incipient anodes in the immediately adjacent locations. Repair mortar The shrinkage-compensated reinstatement mortar shall be Guncrete E, a single component cement-based blend of powders to which only the site-addition of clean water shall be permitted. The cured mortar shall achieve >45 MPa compressive strength at 28 days. Drying shrinkage measured to ASTM modified 23°C/RH50% shall be not greater than 500 microstrain at 7 days and 700 microstrain at 28 days. March 2014 Page 1 March 2014
