General Description
PROMATECT® 40 is Promat’s newest matrix technology of binding organic
materials and inorganic minerals within a calculated mineral matrix to form a monolithic core. Known
as PromaX® technology
Cement Bound Matrix board, this low energy environmentally friendly manufacturing process makes an excellent boards that offers
superior physical strength, robustness and performance.
PROMATECT® 40 is off-white in colour. One face is extremely smooth
and ready to form a finished surface able to receive almost any form of architectural/finish treatment. The reverse face has a fibre mesh reinforcement (visible).
PROMATECT® 40 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
fully saturated PROMATECT® 40 retains up to 95% of its physical
strength.
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 transportation and the disposal of the product to landfill. They can be placed in on-site rubbish skips with
other general building waste which should then be disposed by a registered contractor in the appropriate and approved manner.
