Mapei Mapeflex MS 45 | Universal Paintable Elastic Sealant and Adhesive, Compatible with Damp Substrates

A SINGLE PRODUCT THAT BOTH SEALS AND BONDS. AND THAT ISN’T AFRAID OF WATER: MAPEFLEX MS45 IS A UNIVERSAL ELASTIC SEALANT AND ADHESIVE, ALSO COMPATIBLE WITH DAMP SUBSTRATES

Description

A one-component, flexible, thixotropic, quick-hardening, sililated polymer-based hybrid sealant and adhesive with a high modulus of elasticity, paintable, suitable for damp substrates, and capable of accommodating movement up to 20%.

Uses

Mapeflex MS 45 has been specifically developed for sealing expansion, fillet and distribution joints on horizontal and vertical surfaces. It is also recommended to form internal and external flexible bonds between similar and dissimilar materials commonly used in the building industry and to replace or integrate mechanical fasteners.

Characteristics & Advantages

• Made of sililated polymers, free of silicon and isocyanates

• Does nor blister even during damp conditions, compatible with damp substrates during application

• Single product for elastic bonds and seals

• High initial “sucker” effect for bonding on vertical surfaces and ceilings

• Has a longer shelf life, up to 15 months in its original packaging in a dry, cool place

• Mapeflex MS45 forms a better bond on compact and absorbent substrates compared to neutral silicone

• High elasticity for sealing joints and cracks in walls and floors

• Paintable: use a flexible paint such as Elastocolor Paint

Application

Used as sealant:

• Sealing expansion, fillet and distribution joints subject to movements of up to 20% of the average width of the joint

It is most frequently used for the following applications:

• Raditional façades

• Ventilated façades

• Civil and industrial floors, including those subject to heavy vehicular traffic

• Window and door fittings

• Cracks and splits

• Paintable joints

• Tin roofs and metalwork

Used as flexible adhesive:

• When applied at a thickness of 3 mm, it forms a flexible bond between most building materials, including many types of plastic

• Its high bond strength without primer and its rapid polymerisation make Mapeflex MS 45 easy to use when installing building elements or bonding construction features, both internally and externally

The product bonds on the following:

• Cement and cement-based materials

• Bricks

• Steel

• Copper

• Aluminium

• Painted surfaces in general

• Glass and mirrors

• Gypsum

• Wood and wood-based materials

• Ceramic and klinker

• Insulating materials in general

• Many types of plastic
