POLYGREY

Single-component technical sealant for structural assemblies

Product line: Technical sealants for structural and multi-material assemblies

DESCRIPTION AND FUNCTION

POLYGREY is a fast-curing, single-component adhesive sealant based on MS Polymer™, which cures through exposure to atmospheric moisture. It provides high initial strength, excellent adhesion, and allows elastic joints and seals to be made between a wide range of materials.

Guaranteed features:

• Non-sagging; can also be applied vertically

• Practically no shrinkage

• Excellent adhesion to a wide range of substrates

• Free from solvents and isocyanates

• Resistant to ageing, UV rays, and weathering

• Suitable for indoor and outdoor use

• Flexible from –40°C to +100°C

• Neutral cure, low odour, non-corrosive

• Compatible with many paint systems (always carry out a preliminary test)

APPLICATIONS

• Installation and sealing of insulating panels, frames, and partition walls

• Bonding and sealing of painted wood panels, plasterboard, plastic laminate, rigid PVC, masonry, frames, and metal structures

• Bonding overlaps between sheet metal or metal components and non-weldable surfaces

• Bonding metal profiles to glass, plastics, and sheet metal panels in the refrigeration industry, refrigerated counters, furnishings, and vehicles

• Sealing and bonding in air conditioning and ventilation systems
