Chemolan M50

Product description:
CHEMOLAN M50 is a Moisture Curing Single Component , solvent free, unpigmented PUR binder of medium viscosity. It is based on MDI and TDI.

Fields of application:
CHEMOLAN M50 is used as a moisture curing binder for recycled granules for in situ base mats. Depending on the type of surface, these mats are coated with a CHEMAL top sealer, a structural spray coating or a self levelling coating in order to obtain weather resistant and permanently elastic synthetic coatings. CHEMOLAN M50 can also be used for the installation of coloured EPDM granule mats, which are common surfaces for ball game courts, school playgrounds or athletic tracks.

Properties:
Due to the medium viscosity, CHEMOLAN M50 is easily mixed with the rubber granules and there is hardly any run-off from the granules. CHEMOLAN M50 is suitable for low and high temperature applications. The long cure time of CHEMOLAN M50 allows day construction joints to be easily and correctly made. The yellowing which occurs when CHEMOLAN M50 is exposed to UV light does not affect its mechanical properties. It is most evident with some colours of EPDM granules. Blue granules will turn to green, grey granules may become yellow beige. These colour changes occur within the first hours, or days, after application, depending on the weather conditions. After a while the original EPDM colour appears more and more due to the abrasion of the thin layer of Chemolan M50 on top of the granules. It is recommended that, in the cases of sensitive colours (blue, beige etc.), a supplementary sealing is applied using the corresponding colour of light stable CHEMAL PE3AB LACQUER LL. Using yellow, red, orange or black granules, the yellowing of CHEMOLAN M50 is usually not so apparent.
