SABA Sabatack 780 MS Polymer Adhesive and Sealant

Description

Sabatack 780 is a one-component MS polymer adhesive and sealant for elastic bonding and seam sealing where high initial tack and strong final strength both matter. It is used on frames, profiles, sheet metal, and panel joints across vehicle manufacturing, marine work, HVAC fabrication, equipment assembly, and general construction where crews need a standfast bead that cures with ambient moisture.

Sabatack 780 Benefits

• High initial tack helps hold parts in place during assembly, which can reduce the need for temporary fastening on vertical and overhead work.
• MS polymer chemistry stays permanently elastic, which helps joints handle movement, vibration, and thermal cycling in service.
• Broad adhesion range supports bonding on many common shop substrates, often without a separate primer step.
• Solvent-free, silicone-free, and isocyanate-free formulation fits shops that want a cleaner handling profile.
• Paintable wet-on-wet finish helps teams move straight into finishing work when the coating system is compatible.

Buyers usually reach for this adhesive when they need one material that can both bond and seal on transportation, marine, and industrial assemblies. The product is supplied in 290 mL cartridges and 600 mL sausages, with standard colors including white, grey, and black, so it fits both bench dispensing and higher-volume production setups.

Common Applications for Sabatack 780

• Elastic bonding of frames, profiles, plates, and trim in bus, coachwork, and specialty vehicle builds.
• Sealing horizontal and vertical seams, overlaps, and joints in marine and HVAC assemblies.
• Bonding sheet metal and fabricated parts in metalworking and equipment assembly.
• Construction and prefab work where indoor and outdoor exposure both matter.
• Plastic technology and civil infrastructure assemblies that need a durable, flexible bond line.

Surface Prep and Use Notes

Bonding surfaces should be dimensionally stable, dry, homogeneous, and free of grease, oil, dust, and loose material before application. Apply the bead in one continuous motion to avoid trapping air, and tool the joint with neutral, acid-free soapy water when finishing is needed. Cure speed changes with humidity and temperature, so colder or drier conditions will slow the set.

Technical Details and Documentation

Verified manufacturer data for Sabatack 780 lists an air-moisture-curing MS polymer with about 8 minutes skin formation time, about 10 minutes open time, Shore A hardness around 55, tensile strength around 3.6 N/mm2, elongation at break around 240%, shear strength around 1.8 N/mm2, and service temperature from -40 C to +120 C, with short exposure up to +180 C. Review the current data sheet before production use, and see SABA for manufacturer support.
