Sarnafil® TS 77-15 | MCT CHEMICALS | SIKA PAKISTAN PRIVATE LIMITED

Description

Usage: Sarnafil® TS 77-15 is ideal for:

• Mechanically fastened roofing systems.
• Applications requiring high dimensional stability and resistance to environmental influences.
• Roofing projects in hot and tropical climates.
• Re-roofing over existing, carefully cleaned, and leveled bituminous roofing.

Application:

• Surface Preparation: Ensure the substrate is clean, dry, and free from contaminants such as dirt, oil, grease, and coatings that may hinder adhesion. For metal substrates, degrease with Solvent T 660 before adhesive application.
• Installation Method: Sarnafil® TS 77-15 is installed by loose laying without stretching or installing under tension. Overlap seams by 80 mm, weld immediately, and fix to the substructure using Sarnabar® fasteners. At upstands and penetrations, secure the membrane with Sarnabar®. The 4 mm diameter S-Welding Cord protects the roof covering against tearing and peeling off by wind uplift.
• Welding: Overlap seams must be welded using electric hot air welding equipment. Welding parameters, including temperature, machine speed, airflow, pressure, and machine settings, must be evaluated, adapted, and checked on-site according to the type of equipment and climatic conditions prior to welding. The effective width of welded overlaps by hot air must be a minimum of 20 mm.
