ABSTRACT:
The present invention relates to a dust suppressant composition comprising a aqueous solution of polyvinyl alcohol, acrylic-based latex, glycerin, silicone based surfactant and a polysiloxane-based wetting agent. Preferably, the composition comprises from about 10 to about 46% of polyvinyl alcohol, from about 20 to about 60% of an acrylic-based latex, from about 0.6 to about 7.0% of glycerin, from about 0.1 to about 1.5% of silicone-based surfactant and from about 0.001 to about 0.5% of polysiloxane-based wetting agent. The composition provides a polymer film over a dusting material thus forming a homogeneous and resistant layer. The instant composition, which is applied over the dusting material (preferably sprayed over the material) and dried at room temperature, presents a low surface tension resulting in better wetting of the particulates and agglomeration of the material. The latter two properties ensure that there is less breakage of the polymer film during continuous use or application (e.g. during transportation of the dusting materials). Said surface tension is between about 20 and about 27 dynes/cm, and preferably of about 25 dynes/cm.
