On the basis of the successful development of advanced adhesive types both domestically and internationally, TLS-401 adhesive steel has boldly innovated, especially by introducing advanced nanotechnology into the adhesive solution. By using the mutual solubility of nano inorganic materials and adhesive resins, its adhesive performance is enhanced and it has excellent construction performance. At the same time, advanced formula design is adopted to make the comprehensive performance of the cured resin more superior.
