Descripción
Mapeflex MS Crystal is a thixotropic adhesive and sealant made from silicone polymers and therefore does not contain silicone or isocyanates.
Compared to polyurethane products, Mapeflex MS Crystal is easier to apply and softer (especially when applied at low temperatures), has a wider application temperature range, does not swell even in particularly humid conditions, is more resistant to UV rays, its surface fixes faster, has a longer shelf life and is supplied in standard plastic cartridges.
Compared to neutral silicone products, Mapeflex MS Crystal adheres better to compact and absorbent substrates, drastically reduces the amount of dirt that accumulates on the surface, has greater strength and cut resistance and can be painted with normal elastomeric paints.
CHARACTERISTICS
Mapeflex MS Crystal can also be applied on substrates that are temporarily wet due to unsuitable environmental conditions (just after rainy weather, when in contact with water, if there is humidity in the atmosphere, etc.). If there is continuous capillary rising damp, apply a coat of Primer FD beforehand. If applied to wet substrates or substrates continuously submerged during service, the mechanical performance of the product could be significantly lower compared to use in dry conditions.
Mapeflex MS Crystal does not contain a solvent, has a very low emission of volatile organic compounds and is characterized by its high mechanical resistance in accordance with ISO 11600 standards (class F20 HM).
Mapeflex MS Crystal sets by reacting with moisture in the air without emitting significant levels of liquids or gases that could be potentially hazardous to the user or the environment; therefore, hazard warning labels on packaging are not required. The product is delivered ready to use and is available in plastic cartridges for use with standard caulking guns.
Mapeflex MS Crystal complies with EN 15651-1 ("Sealants for internal and external facades") with performance classification F-EXT-INT and EN 15651-3 ("Sealants for sanitary joints") with performance classification XS1.
IMPORTANT NOTICES
- Do not apply to dusty or crumbling surfaces.
- Do not use on surfaces with traces of oil, grease or form release compound; Adhesion may be affected.
- Do not apply on bituminous surfaces where there may be traces of bleeding oil.
- Do not apply if the temperature is below +5°C.
- Use elastomeric paint to paint over the sealant.
- If exposed to UV rays, the surface may yellow.
FIELDS OF APPLICATION
Mapeflex MS Crystal is specifically formulated to form a highly transparent sealant and adhesive with the ability to seal and bond without affecting the appearance of the items on which it is used.
Some application examples
Used as a sealant:
Elastic sealant and filler for internal and external spaces, such as cracks and crevices, splices and expansion joints subject to movement of up to 20%. It is most frequently used for the following applications:
• facades;
• internal partition walls;
• glass partition walls;
• fill gaps between skirting boards and floors;
• window and door fittings;
• shower cabins
Used as elastic adhesive:
A thin layer is sufficient to form an elastic bond in the most commonly used building materials. Ideal for joining transparent glass and plastic objects *. Ideal for joining glass shelves and lids and glass objects in general.
Mapeflex MS Crystal also adheres to many other types of building materials, such as:
• cement and cement-based materials;
• bricks;
• metals such as copper, aluminum and prepainted
surfaces;
• glass and mirrors;
• and so;
• wood and wood-based materials;
• ceramics and clinker;
• insulating materials in general;
• many types of plastic *.
