III. Scope of Application

  Widely used in fields such as stone materials, wood, paper, concrete, perlite insulation boards, and waterproof coatings, providing them with excellent water resistance, protection against weathering, or significant reduction of weathering effects. It can be mixed with other additives to serve as a filler for waterproof and thermal insulation materials, as well as a sealing agent. Alternatively, it can be applied directly as a standalone waterproofing material, such as the water-retention powder used in road construction or the cementing agent employed in drilling operations.


IV. Product Applications

  Used in the production of silicone waterproofing agents, potassium methylsilicate, sodium methylsilanediolate, Fangshenwang Lou, waterproofing agents, nano-silica waterproofing agents, silicon-fluorine waterproofing agents, "Simplicity" spray-type waterproofing solutions, DPS, and condensation water raw materials. It can also be mixed with other additives to serve as a filler for waterproof and thermal insulation materials, effectively stopping leaks. Additionally, it is directly applicable as a waterproofing material in applications such as road cement and drilling gel consolidants.


V. Precautions for Use

  When operating, wear protective equipment. If product accidentally comes into contact with eyes, immediately rinse thoroughly with clean water. During construction, perform a contact test on other materials that may be touched to ensure there are no adverse effects. Before conducting large-scale application, first carry out a small-scale trial locally to verify the effectiveness and determine the optimal dosage.


VI. Packaging and Storage

  Packaging: 25 kg plastic woven bags with two additional plastic liners.

  Storage: Should be stored in a cool, dark, and tightly sealed place.
