Chemolan M

Product description:
CHEMOLAN M is a moisture curing, solvent free, unpigmented PUR binder of medium viscosity. It is based on TDI.

Fields of application:
CHEMOLAN M 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 M 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 M is easily mixed with the rubber granules and there is hardly any run-off from the granules. CHEMOLAN M is suitable for low and high temperature applications. The long cure time of CHEMOLAN M allows day construction joints to be easily and correctly made. The yellowing which occurs when CHEMOLAN M 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 M 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 M is usually not so apparent.
