First of all, silicone waterproofing agents can be divided into silicates, silicone oils, silanes, and silicone resins according to their main components.
They will be introduced in turn below:
1. Silicate waterproofing products
First, let’s talk about the more common silicates, potassium methylsilicate and sodium methylsilicate. These products are water-based and highly alkaline. Because of its lower price, it is mainly used in cost-sensitive areas such as brick roads. The construction technology is generally dipping and spraying, and the waterproofing life is generally 3-5 years.
2. Silicone waterproof products
Then there are silicone waterproofing products based on silicone oil, silane, and silicone resin. Such products can be water-based, which is environmentally friendly and easy to operate, or oil-based, which increases the penetration depth of the surface coating when dipping.
Through reaction, it can be cross-linked into a network structure to form a waterproof film on the surface and pores of the substrate. Achieve the lotus leaf effect without affecting the passage of water vapor.
The higher cross-linking density improves the weather resistance, acid and alkali resistance of the waterproof layer. The diversity of groups gives the waterproof layer different properties such as waterproof, oil-proof, anti-fouling, and anti-icing.
The excellent application performance of such products can meet the different needs of different customers on different substrates. The construction technology can be internal mixing, spraying, dipping, etc. The waterproof life is generally 5-10 years.
