NJ-1003/NJ-1003T Expansive Agent
NJ-1003 and NJ-1003T are plasticizers. NJ-1003T is a more efficient product than NJ-1003, with the following features:
In alkaline environments, forms uniform and dense micropores during the plastic phase, enabling micro-expansion to prevent shrinkage caused by moisture evaporation. After hardening, it maintains its volume without adverse effects on strength. The product is odorless, safe, and environmentally friendly.
scope of application
This product is widely applicable to various cement-based grouting, mortar and concrete systems, especially suitable for building materials products used in filling or pouring scenarios, such as grouting agents (materials), grouting materials and various grouting materials.
