Based on solids

The viscosity of the product is affected by the pH value, as the pH value increases, the viscosity and thixotropy will increase.

Application
When used with water-based isocyanate curing agent, the curing agent needs to be diluted to 60-70% with a suitable co-solvent such as PGDA or PMA+DBE (1:2) before use. At the same time, the main agent and curing agent need to be fully stirred after mixing. The ideal mixing method is to mix with a pneumatic or electric stirrer, and then dilute with water. It is generally recommended to dilute with water at 5~25% of the main agent.
It has excellent wettability and can be used in grinding, but attention should be paid to the grinding time (<2h) and grinding temperature (<50℃). There are many unstable factors in the grinding process, which may lead to decreased stability.
