PROMINA®-HD
 
General Description
 
PROMINA®-HD is a non-combustible fibre silicate board manufactured from a homogeneous mixture of Portland cement with selected fibres and fillers. It is formulated without inorganic fibres and does not contain formaldehyde. It is designed for both internal and external applications. The product is also designed to withstand the most demanding of exposure conditions experienced in external applications as well as being hard wearing, impact and abrasion resistant
PROMINA®-HD is off-white in colour and has a smooth finish on one face with a dimple pattern on the reverse face. PROMINA®-HD provides an architectural surface ready to receive most forms of decoration. Please consult the Promat Technical Department for more information.
PROMINA®-HD is resistant to the effects of moisture and will not physically deteriorate when used in damp or humid conditions. Performance characteristics are not degraded by age or moisture.
A health and safety data sheet is available from the Promat Technical Department and, as with any other materials, should be read before working with the board. The board is not classified as a dangerous substance so no special provisions are required regarding the carriage and the disposal of the product to landfill. They can be placed in an on-site skip with other general building waste which should then be disposed by a registered contractor.
