FixTech Fix15 MS Polymer Adhesive Sealant 290ml

FixTech Fix15 is a high strength, flexible MS Polymer adhesive and sealant for demanding outdoor, caravan, 4WD, marine and solar installations. Available in black or white, Fix15 combines strong structural adhesion with permanent flexibility, making it particularly useful for bonding solar panel brackets, cable entry covers, fittings, panels and other accessories where vibration, movement and exposure to the weather are part of everyday use.

It bonds to a wide range of common materials including aluminium, stainless steel, fibreglass, glass, timber, PVC, composites, painted automotive surfaces and many other substrates, often without requiring a separate primer.

Strong Bond Without Becoming Brittle

Fix15 develops a strong structural bond while remaining flexible after curing. This makes it well suited to vehicles, caravans and boats where bonded components are exposed to vibration, thermal expansion and movement rather than remaining completely static.

The cured adhesive provides a tensile strength of 2.2N/mm², shear strength greater than 1.6N/mm² and elongation at break greater than 300%.

Ideal for Solar & Touring Installations

Fix15 is a practical option for permanently bonding and sealing components such as:

• rigid solar panel mounting brackets

• solar cable entry covers

• canopy and caravan fittings

• roof mounted accessories

• aluminium and composite panels

• external trim and fixtures

• marine fittings and hardware

For flexible solar panels, always follow the panel manufacturer's current mounting instructions rather than assuming a structural adhesive is suitable for every panel design.

UV & Weather Resistant

Fix15 is designed for long term exterior use and is resistant to UV exposure, ageing and weather. Its MS Polymer formulation also performs well in wet and humid environments, making it suitable for caravan, 4WD and marine installations where the adhesive may regularly be exposed to rain, washing or coastal conditions.

FixTech specifies the product for both above and below waterline applications when correctly prepared and applied.

Black or White

Choose the colour that best suits the installation.

The white formulation is designed to remain non-yellowing, making it well suited to white caravan roofs, fibreglass surfaces and light coloured fittings.

Black is useful around black solar brackets, dark canopies, trim and installations where a darker finished bead blends in more naturally.

Both colours use the same Fix15 MS Polymer adhesive technology and performance specifications.

Moisture Curing MS Polymer

Fix15 is a single component moisture cure adhesive, so no mixing is required. At approximately 23°C and 50% relative humidity, skin formation occurs in around 15 to 30 minutes, with a cure rate of approximately 3mm every 24 hours. Actual curing time varies with bead thickness, temperature, humidity and the materials being bonded, so sufficient cure time should be allowed before loading the joint.

Primerless Adhesion to Many Surfaces

Fix15 can achieve strong adhesion to many clean and correctly prepared substrates without a separate primer. Typical compatible materials include aluminium, stainless steel, mild steel, fibreglass, composites, glass, timber, PVC, acrylic, polycarbonate, ceramic, rubber and painted surfaces.

Because surface coatings and plastics can vary significantly between manufacturers, compatibility testing is recommended before committing to the final installation.

Paintable Finish

Fix15 can be painted, making it useful where the finished installation needs to blend into surrounding bodywork or panels. Surface preparation and paint compatibility should be checked before completing the final installation.

Application

Apply using a standard manual or pneumatic cartridge gun to a clean, dry and correctly prepared surface. FixTech specifies an application temperature between +5°C and +35°C. Uncured adhesive can be cleaned with methylated spirits or industrial alcohol cleaner. Once cured, excess material generally needs to be removed mechanically.
