Applications & Use Cases
- ▸ Used as a penetrating concrete densifier and hardener that reacts with free calcium hydroxide to form additional calcium silicate hydrate, raising surface abrasion resistance on polished and industrial floors.
- ▸ Serves as the inorganic binder in heat-resistant, intumescent, and zinc-rich anti-corrosion coatings, forming a hard glassy film on curing.
- ▸ Functions as a low-VOC water-based binder and adhesion promoter for mineral, ceramic, and high-temperature protective coatings.
- ▸ Acts as a surface-sealing and dustproofing treatment for cementitious substrates, reducing porosity and improving stain resistance.
- ▸ Employed as a binder and refractory additive in foundry coatings, welding electrode coatings, and ceramic bonding applications.
