High Tack is a powerful, high-performance sealant and adhesive based on SMX Polymer Technology. It delivers extremely high initial tack and final bond strength (up to 320 kg/10 cm²), making it ideal for flexible bonding and sealing in demanding construction and industrial applications. It adheres to nearly all surfaces—porous, non-porous, even damp or wet—without the need for priming. Formulated with XS1 fungicide, it also offers exceptional resistance to mold, making it suitable for sanitary and humid environments.
