Refractory hardener Si 1530 / Si 2040

Price: on request

Hardener of Si 1530 / Si 2040 of alkaline colloid 30% or 40% solution of nanoparticles SiO2 in water. By sight - opal, milky-white liquid with slightly bigger viscosity, than water. It is applied to processing of surfaces of layings or products from ceramic fibers for reduction of loss of fibers from layings in working space in sensitive productions, and also for increase of durability and resistance of surface to external influence.

Properties:
• high viscosity;
• stable in alkaline condition;
• in acidic environment means turns into gel;
• possibility of supply of non-freezing mixture to -15 0C;
• simple drawing by plastering, splashing or wetting;
• homogeneous structure.

Application:
• rejection of layings of furnaces from ceramic fibrous materials;
• processing of surfaces in places of high speed of combustion products;
• hanging of resistance to separation of fibers;
• increase of resistance to deleting;
• finishing of front edges;
• increase of durability of shaped parts from fibrous materials;
• protective coating for increase in endurance of product;
• improvement of surface of shaped parts and products.

Standard packaging:
• plastic canister 6 and 12 of kg;
• plastic barrel of 70 and 240 kg;
• boxing pallet of 1200 kg.
