Retarder is an additive precisely formulated to slow the setting time of Jesmonite AC100/200/300 composites.
Perfectly suited to complex, large-scale applications, it enables controlled extension of working time, without compromising either the surface appearance or the mechanical performance of the material.
Its flexibility of use means that the pace of implementation can be adjusted according to both technical and climatic constraints.
Retarder is particularly recommended during the summer months, as it compensates for heat-induced setting acceleration, offering optimal, constant working comfort.
⚖️ Mixing ratio: 2 to 8 gr per kilo of liquid
🌿 Solvent- and VOC-free
⏱ Up to 45 min. working time
💧 Maintaining physical properties
1. Mixing ratio
Add between 2 and 8 grams of retarder per kilogram of liquid Jesmonite, before incorporating the powder base. The exact quantity depends on the level of retardation required and the specific constraints of the project.
2. Pot life
The resulting working time varies according to several factors:
It is strongly recommended to carry out a preliminary test to determine the exact working window for your specific production conditions.
Note: Excessive dosage may alter mechanical properties or prolong drying time. It is therefore essential to adjust the formulation rigorously, taking into account application conditions and the type of part to be produced.
