Silicone Hydrophobic Powder PD8200 for Dry Mixer
Product Description
ADHES® PD8200 Silicone Hydrophobic Powder is an encapsulated silane in powder form and it produced by spray-drying. It provides outstanding hydrophobized and water repellent properties on the surface and bulk of cementitious based building mortars. The active ingredient of PD8200 is released when the mortar is mixed with water and it subsequently binds covalently to the inorganic mortar matrix. PD8200 is easy to mix during production of cementitious based dry mix products. It improves the water resistance and durability of cementitious based products even at very low dosage. It is also fully efficient in alkaline medium, typically a pH of 10 -12.

Application
PD8200 Silicone Hydrophobic Powder is used as special additive for:
➢Waterproofing
➢Cement-based mortar systems
➢Plasters, renders, joint fillers, sealing mortars/slurries
➢High degree of hydrophobicity is required with cement-based mortar systems.
Performance
Used for powder waterproof cement-based system, improve water repellent
➢ Reduce water absorption
➢ Improve the durability of cement-based building materials
➢ Linear relationship between hydrophobicity and additive quantity
During the hardening phase
➢ Low additive amount
➢ Wettability and good mixing performance
➢ Excellent construction performance
➢ Good durability
➢ Long-term storage stability
➢ Keep the physical property of cement mortar
➢ Free flow without dust
➢ Good compatibility with other additives
