STELMAX 1965 Filler and Sealant – White

The Stelmax 1965 is a professional-grade, solvent-based PVC resin gap filler and sealant specifically formulated for the window industry. Unlike standard silicones, it is designed to chemically bond with uPVC, drying hard to form a permanent, maintenance-free joint that exhibits the same weathering and UV-resistant properties as the window frame itself.

Key Features
PVC Resin-Based Formula: Composed of a mix of PVC resin, pigments, and solvents that effectively weld to rigid and plasticised PVC for exceptional bond strength.

Specialised for Small Gaps: Specifically designed for fine finishing and sealing joints within the window frame, such as mitre joints and trim attachments.

Maintenance-Free Finish: Once cured, the surface is hard and wipeable, resisting UV yellowing, chemical cleaners, and harsh weathering.

Rapid Skinning: Formulated to skin over quickly to prevent dust and debris from contaminating the surface during the curing process.

Wider Compatibility: While optimised for uPVC, it also offers good adhesion to many porous substrates including timber, brickwork, and masonry.
