Recommended Dosage
It is believed that the addition of STMP to the slurry promotes long crystal growth. Such crystals add the most strength to the core of the wallboard and also serve to form stronger bonds between the core and paper. While in theory, STMP can be used by manufacturers to decrease costs by increasing the core quality of wallboard, it has been discovered in practice that the current methods of adding STMP leads to further problems and delays.
