part of the asbestos replacer serve to retain moisture and add plasticity and viscosity when used in conjunction with the finely divided mineral clays or fillers used in the asbestos replacer formulation dispersant may be any type such as ionic or anionic polymers that are compatible and effective with portland cement dispersants may be used in a range from 0 02 to 4 00 of the cement used in the mortar dispersants are plasticizers which reduce the amount of water necessary to wet out the finely divided clays and mineral fillers in the asbestos replacer and aid in dispersing the asbestos replacer into the mortar mix thereby increasing the effectiveness of the formulation wetting agents may be of any type such as sodium salts that are compatible and effective with portland cement wetting agents help the clays and thickeners to retain water while completely wetting out the components of the asbestos replacer and cement used in the mortar mini fibers mini fibers may be synthetic or natural fibers ranging up to 1 2 34 in length and are useful ingredients for the formulation in order to separate the other finely divided components such separation allows for easier disbursement of the components in water or the mortar mix these mini fibers may comprise for example polyethylene aramid nylon rayon silk mineral fibers and the like in addition to mini fibers also add viscosity strength and water retention to the cementitious mortars finely divided mineral fillers including but not limited to limestone or silica may be added to the asbestos replacer to separate the other finely divided components the finely divided mineral fillers also increase the water retention and improve the workability of the cementitious mortars other ingredients may.
