Description
Silicone Water Rellent TPD-WR27E is a silane/siloxane emulsion. It is an excellent penetration waterproofing agent, when TPD-WR27E is coated on the surface of the substrate, it will penetrate into the substrate and does not block capillary. Hydrophobic film can be formed by the reaction of reactive groups, and combined with hydroxyl groups in the substrate to form a Si-R siloxane chain. It will fill the micro pores, improve the strength of the substrate. After the construction, it can reach high water resistance ability.
Features
- Low molecular structure, can penetrate into the substrate surface to provide protection, penetration depth is: 2-10mm.
- Greatly reduce the water absorption of the substrate
- Does not affect the appearance of the substrate, improve anti-efflorescence ability and prolong the life of the substrate.
- Water-Soluble, low VOC.
