Flexible structural bonding
For bonding materials with significantly different thermal expansion coefficients that are exposed to vibration, we recommend MONOFLEX MS 611-1. In addition to MS 611-1, we also offer a similar adhesive Alpha DP007.
This is an elastic adhesive – a sealant based on a silane-modified polymer. This adhesive cures to a rubber-like form due to moisture in the air. In summer and during the heating season it is important to ensure that the room in which the gluing process is carried out is sufficiently humid.
Purpose of MONOFLEX MS 611-1 adhesive:
- Bonding of floors of buses, trams, refrigerated trucks, semi-trailers, etc.
- Bonding of vehicle body panels,
- Bonding of multi-layer panels,
- Bonding of glass panes in skylights, covers in machine tools, etc.
- Bonding of sheet metal reinforcements, doors and sheet metal covers, etc.
Advantages of MONOFLEX MS 611-1:
has excellent adhesion to metals, steel, stainless steel, glass, plastics, plexiglass, paint, etc.
The joint acts as a vibration damper, compensating for stresses caused by differences in thermal expansion,
Prevents corrosion – joints are sealed,
One component – easy to apply,
UV resistant (no yellowing),
Paintable – can be painted after curing.

Przeznaczenie kleju MONOLITH SE 131-1 i SE 132-1:
MONOLITH SE 131-1 and SE 132-1 (formerly SE 105-1, now replaced by SE 132-1) are recommended for flexible structural bonding of components made of various materials, including those that are difficult to bond, with high impact resistance. SE 131-1 has a higher viscosity than SE 132-1 and allows bonding with a maximum gap of up to 5 mm instead of 0.5 mm. SE 132-1 is also suitable for coating and encapsulating electronic components. It is self-leveling.
These are two-part adhesives based on a modified epoxy hybrid that cures by chemical reaction to a hard elastic mass:
- For elastic bonding of metals, steel, difficult to bond plastics, for bonding a wide variety of materials,
- Elastic sealing of seams and joints in vehicle construction, containers, ventilation and air-conditioning systems.
- Bonding of construction elements with high requirements for impact resistance – bonding of glass panes in military armoured equipment (opinion WZI – 985/WT concerning SE 105-1), in bank vehicles, etc.
Benefits of MONOLITH SE 131-1 and 132-1 adhesives:
- adheres to many substrates, no primer required,
- high viscosity, will not run off vertical surfaces,
- has no shrinkage, the joint is even on the surface, without tension,
- does not contain solvents, isocyanates, silicones, PVC, is virtually odourless,
- is practically odourless, has a high tolerance to disproportioning of mixed components,
- can be painted after curing
- cures at room temperature
- easy to apply – can be used in most weather conditions
- soft and flexible
