Description
Permabond MS359 Clear MS Polymer Adhesive
Permabond MS359 Clear is a single-part, moisture-curing MS polymer adhesive developed for clear, flexible bonding applications where weather resistance, appearance and versatility are important.
Unlike UV-curing glass adhesives, MS359 Clear does not require UV light to cure, making it ideal for larger bonded areas, opaque materials and applications where UV access is restricted.
Its crystal-clear finish and non-yellowing formulation make it particularly suitable for decorative glass bonding, displays, mirrors, construction assemblies and exterior applications requiring an aesthetically clean bond line.
MS359 Clear combines flexibility with strong adhesion to a wide range of substrates including glass, metals, composites, wood and plastics.

Why Choose MS359 Clear?
MS359 Clear is ideal where a flexible, transparent bond is required without the need for UV curing equipment.
Compared with rigid UV adhesives, MS359 offers:
- better flexibility
- larger gap-filling capability
- easier application on larger surfaces
- excellent outdoor durability
- improved vibration and movement resistance
This makes it particularly suitable for construction, decorative and display applications where thermal expansion or movement may occur.

Surface Preparation
For best adhesion:
- Ensure all surfaces are clean, dry and grease-free
- Degrease using isopropanol or acetone where suitable
- Light abrasion may improve adhesion on some metals
- Apply adhesive evenly to the bonding surface
- Clamp or support components during cure if required
Indoor & Outdoor Performance
Permabond MS359 Clear is designed for long-term durability in both interior and exterior environments. Its weather-resistant, non-yellowing formulation makes it suitable for visible bonded joints exposed to UV, moisture and temperature variation.
