Mapeflex MS 45 is a thixotropic adhesive and sealant made from sililated polymers and thus completely free
of silicone and isocyanates.
Mapeflex MS 45 is easy to extrude and smooth over (even when applied at low temperatures), has a wide
application temperature range, does not blister even during particularly damp conditions, is compatible with
damp substrates during application, is resistant to UV rays, hardens quickly, has a long shelf life.
Furthermore, Mapeflex MS 45 forms a better bond on compact and absorbent substrates, efficiently reduces
the amount of dirt which collects on the surface, offers good mechanical properties such as tensile and shear
strength. Before painting over Mapeflex MS 45 it must be fully polymerised and the paint used must be
flexible, such as Elastocolor Paint, elastomeric, crack-bridging, permanently flexible, protective paint with
high resistance to chemicals for internal and external surfaces.
We recommend carrying out preliminary tests to make sure the sealant and paint are compatible.
Mapeflex MS 45 complies with EN 15651-1 (“Sealants for façade elements”) with performance rating F-EXT-INT
CC, with EN 15651-3 ("Sealants for sanitary areas") with performance rating XS1 and EN 15651-4 (“Sealants for
pedestrian walkways”) with performance rating PW-EXT-INT-CC.
Mapeflex MS 45 contains no solvents, has a very low emission level of volatile organic compounds (EC1 Plus)
and is characterised by high mechanical strength according to ISO 11600 (class F20 HM).
Mapeflex MS 45 may also be applied on substrates which are temporarily wet due to unsuitable surrounding
conditions (recent rain, contact with water, atmospheric damp, etc.); for continuous capillary rising damp,
apply a coat of Primer FD beforehand. If applied on damp substrates or on substrates continuously immersed
when in service, the mechanical performance and the adhesion of the product could be significantly lower
compared to use in dry conditions.
Mapeflex MS 45 hardens by reacting with humidity in the surrounding air without giving significant levels of
liquids or gases potentially hazardous for the user or the environment, which is why no safety warnings need
to be applied on the packaging.
The product is ready to use and is available in plastic cartridges to be used with traditional extrusion guns.
