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.
