Silicon tripolyphosphate - potassium sodium silicate curing agent
I, Preface
Due to the existence of alkali metal ions that are easily soluble in water, the potassium silicate still has water-soluble alkali substances after curing, which leads to poor water resistance, easy to regain moisture, and is not suitable for wet environment. Therefore, water glass as the base material must be added with certain curing agent to improve its water resistance and curing performance. Common curing agents include metal oxides, inorganic acids, fluorosilicates, etc. However, there are still many imperfections in the use of these curing agents. Therefore, a new type of curing agent - "silicon tripolyphosphate" was developed on the basis of the original curing agent.
II, Product characteristics
The potassium silicate curing agent "silicon tripolyphosphate" is a non-toxic and odorless white powder. It does not melt at high temperature and becomes a colloid. Silicone phosphate curing agent has the characteristics of short curing time, high efficiency, environmental protection, high temperature resistance and waterproof.

IV, Product features
(1) The product is non-toxic or low-toxic, and the production process is pollution-free.
(2) The curing speed is moderate and there is no early setting or non-condensing phenomenon.
(3) fter curing, the performance is better than that of the previous curing agent and reaches the industry standard.
(4) It not only effectively overcomes the shortcomings of traditional curing agent, but also has no pollution and conforms to the environment The need for protection.
V, Scope of use
In addition to being used as potassium silicate curing agent, silicon tripolyphosphate can also be used as lime curing agent and cement curing agent; Special optical glass; Inorganic coating; Ingredients of high-strength cement and acid-resistant adhesive; Waterproof adhesive curing agent; Non-toxic antirust coating and organic synthesis catalyst.
VI, Usage and dosage
6.1 Mixed method
6.1.1 First, soak the silicon phosphate with proper amount of water or directly add the powder into the water glass solution or other material medium and stir evenly.
6.1.2 Dry process: silicon phosphate powder and sodium silicate powder can be mixed directly and used evenly.
