SYUDOX® SG-413 and DSP-2508

Drying Shrinkage Reducing agent 

SYUDOX® SG-413 and DSP-2508 are the liquid type dry shrinkage reducing agents (SRA) developed for mortar or concrete

FEATURES

Excellent effect of dry shrinkage reducing.

     Prevent cracking and reduce dry shrinkage around 10 to 40% in accordance with SYUDOX® series dosage.

Having little impact on the workability and the hardening properties.
No specific performance change can be observed when existing with the expansive additives
