2、 Physical and chemical properties:

Water solubility: It is easily soluble in water at room temperature (it is best to mix it with inorganic substances, and it is easy to clump when dissolved directly in water). Non toxic and harmless, safe and environmentally friendly.

Chemical resistance: At room temperature, the pH value of its aqueous solution is generally around 5-7, the viscosity is stable, and it is almost not affected by weak acids, weak bases, or organic solvents (esters, ketones, higher alcohols, hydrocarbons). It has extremely high oil resistance.

Miscibility: It can be miscible with starch, synthetic resins, cellulose derivatives, and various surfactants with good stability, but long-term storage may result in delamination.

3、 Main purpose:

JC series products can be widely used as additives in various dry powder putty and dry powder mortar in powder chemical building materials; Ceramic tile adhesive, polypropylene dry powder adhesive, plastering gypsum adhesive, etc. It is particularly suitable as an additive for building mortar, which can improve the flexibility and water retention of mortar, increase the viscosity of mortar, reduce the friction of mortar, enhance work efficiency and quality (prevent cracking and peeling of plaster layer, increase adhesion strength and smoothness).
