Structural Adhesives - Aerobolt Bond-Flex

Structural adhesive with high initial grab and permanent elasticity after curing.

Bond-Flex is a high-performance structural adhesive based on MS Polymer® (MSP) technology, providing excellent bonding strength, high initial tack and a strong, flexible bond that remains elastic after curing.

Bond-Flex is designed for a wide range of industrial and construction applications, including commercial vehicle body building, marine, metal fabrication and general construction. Its high initial grab and excellent green strength help reduce the need for temporary support during curing, while its flexible formulation accommodates movement and vibration in suitably designed joints.

Adhesive Bond-Flex Advantages

• Excellent bonding strength: Provides strong adhesion for a wide range of suitable substrates and applications.
• High initial grab and green strength: Helps hold bonded components in position during the curing process.
• Reduced support requirements: High initial tack can minimise the need for temporary support, depending on the weight and configuration of the bonded components.
• Versatile adhesion: Bonds to a wide range of compatible surfaces with appropriate preparation.
• Excellent flexibility: Forms a durable, permanently elastic rubber-like bond after curing.
• Elongation at break: 500% (DIN 53504), as specified in the Bond-Flex technical data sheet.
• Maximum allowed distortion: ±20%, as specified in the technical data sheet. Suitability for joint movement depends on the specific joint design and application conditions.
• Alternative to mechanical fastening: Can reduce the need for traditional fasteners and rivets in suitable, properly designed bonding applications.
• Industrial and construction grade: Designed for demanding bonding and sealing applications.
• UV resistance and colour stability: Offers resistance to UV exposure and helps maintain colour stability.
• MS Polymer® technology: A moisture-curing adhesive formulation that provides a flexible, durable bond.

Adhesive Bond-Flex Applications

• Commercial vehicle body building: Bonding of sidewalls, roofs, doors, door frames, body seams, flooring, trims and other suitable components.
• Sanitary and kitchen areas: Sealing and bonding applications where resistance to moisture and mould growth is beneficial.
• Vibration-resistant bonding: Flexible bonding of components exposed to movement or vibration.
• Sheet metal fabrication: Bonding and sealing of compatible metal components and joints.
• Paintable gap filling and sealing: Suitable for compatible paint systems, subject to preliminary testing.
• Mirror bonding: Bonding to compatible mirror backings, subject to manufacturer recommendations and adhesion testing.
• Panel and insulation bonding: Attaching suitable wall panels, insulation materials and other compatible substrates.
• Natural stone applications: Bonding and sealing suitable natural stone materials where a thick-paste adhesive is required, subject to compatibility testing.

Important Application Information

Aerobolt recommends conducting preliminary adhesion and compatibility testing before using Bond-Flex, particularly when bonding coated, painted, porous or specialised materials.

Surfaces should be clean and free from dust, grease and contaminants. Coated aluminium that has been covered with protective plastic film may require chemical cleaning to remove surface residues before bonding.

Adhesive performance depends on substrate compatibility, surface preparation, joint design, curing conditions and the loads applied. Bond-Flex technical properties, including elongation at break and maximum allowed distortion, should not be interpreted as allowable structural joint loads or universal movement limits.

For detailed technical specifications, surface preparation instructions and application requirements, refer to the manufacturer's current Bond-Flex Technical Data & Safety Sheet.
