                                         CULMINAL® for tile cement

                                         CULMINAL products are widely used to improve the application properties of building
                                         materials based on cement, gypsum and lime. In tile cements they improve water retention,
                                         correction time and open time, and decrease skin formation, slip and sagging.

                                         The straight CULMINAL products are series of methylcellulose mixed ethers (MHEC and
                                         MHPC) with varying viscosity. CULMINAL-C series are modifications in which additives
                                         enhance specific properties as required by special application conditions.

                                         Physically the products are white to off-white powders, that dissolve in cold water.
                                         CULMINAL has a good compatibility with electrolytes like salts, and is stable over a wide
                                         pH range.
    We recognize that our products are required to be perfect in every respect,
    available at the right time, at the right place and in a perfect condition.
    To continuously achieve this, Aqualon declared ‘Total Quality’ one of the highest
    priorities throughout the entire organization. In 1994 all Aqualon entities in Europe
    received ISO 9001 status, an essential milestone in the divisions pursuit of
    achieving business excellence. Quality is no static condition, neither it is some-
    thing that springs up by itself.

    All Aqualon employees follow regular and intensive training in the use of problem
    solving techniques and participate in improvement projects.
    Total Quality is a matter of priority at all levels of the company; this is why the
    combination of product value and service level offered by Aqualon is of the highest
    calibre. For Aqualon quality is a matter of continuous attention.

There is more to quality than a good product and satisfied customers.
In Aqualon’s view quality is also reflected in our attitude towards the environment.
To minimize environmental impact as much as possible during a product’s life-
cycle, it is Aqualon’s objective to achieve ISO 14001 certification for its three
European production units.
Aqualon focuses on its core activity: producing cellulose ethers in many varieties
and perfecting these to meet current and future requirements of its customers.
