RTD 50 retarder can be used in any type of gypsum like natural gypsum or synthetic gypsum. Other retarder’s dose is very high like citric acid 1-2 gram /m2 and it reduces the board strength and develops sagging properties of the board whereas RTD-50 dose is 0.40 to
0.70 gram/m2 and it does not affect the strength of the board. Moreover it improves the anti sagging properties of the board. Proper use of RTD 50 retarder will reduce the water/plaster ratio with good fluidity & remarkable cost saving.
Point of economical operation
- Low water / stucco ratio is always welcome. It saves drying cost, increases dryer efficiency and improves the performance factor.
- No lump formation in the mixer can increase running hours of the mixer and hence the efficiency of the machine will improve.
