MAXFLEX® 100 LM
LOW MODULUS SINGLE COMPONENT POLYURETHANE SEALANT

Description

MAXFLEX 100 LM is a single component, polyurethane elastomeric sealant. The product cures at ambient temperature under the influence of the atmospheric humidity, presenting a low elasticity modulus.

Uses

- Joints in heavy and light pre-fabricated panels, as well as in traditional masonry.
- Waterproof joints in façade panels, curtain walls, exterior glazing, etc.
- Joints between door and window frames, etc.

Aplication

The surface must be sound and clean, free from dust and grease. etc. To seal the joints, it is advisable to use a closed cell polyethylene joint backing rod, such as MAXCEL, of a diameter 25% greater than the width of the joint. MAXFLEX 100 LM has a very good adhesion over construction materials such as concrete, glass, aluminium, etc., without the need of using a primer. Nonetheless in order to improve the adhesion on the edges, a priming can be done using PRIMER 1. Consequently an to prevent staining the edges and provide a better finish, it is advisable to place masking tape on either side of the joint.
For thin joints, MAXFLEX 100 LM should be applied in a single pass. In wider joints, it should be applied in three steps, the first two, on the edges of the joint and the third, filling in the centre. During the application, press against the edges of the joint and against the bottom to prevent air bubbles. To smooth over the surface, soapy water can be used. The application is finished by removing the masking tape.
MAXFLEX 100 LM can be painted over once it has cured completely. Preferably use acrylic or vinyl dispersion paints, and to a trial previously.
MAXFLEX 100 LM can be cleaned before curing, using white spirit. The polymerised product can only be eliminated by mechanical means.
