The most common scenario for hydroxypropyl methylcellulose in construction applications is cement mortar, and hydroxypropyl methylcellulose’s cement mortar has specific requirements for product viscosity. This viscosity requirement will vary depending on the specific application scenario. Generally speaking, the higher the viscosity, the better the water retention, but when the viscosity exceeds a certain range, the effect of viscosity on the water retention is no longer significant.

For mortar, since it requires better water retention and consistency, it is usually recommended to use high-viscosity hydroxypropyl methylcellulose with a viscosity of above 150,000. Such a viscosity ensures that the mortar maintains stable consistency and water retention during mixing, transportation and use, thereby improving its construction performance and durability.

However, it should be noted that the specific viscosity requirements need to be comprehensively considered based on factors such as the type, use, and construction conditions of the cement mortar. Therefore, in practical applications, it is recommended to experiment and adjust based on specific conditions to determine the optimal hydroxypropyl methylcellulose viscosity.
