Polyvinyl alcohol (PVA)is an excellent water-based adhesive.The general product is flake,granular or flocculent.It is not easily soluble in cold water.Heating is generally required during dissolution.After being finely pulverized and surface treated,it has better cold water dissolving performance.But because of its thermoplasticity,pulverization becomes particularly difficult.Our factory adopts a special liquid nitrogen low temperature cooling process to ensure that the powder of the crushed material is uniform.So that the material has excellent water solubility.
Good film formation,adhesion,solvent resistance,friction resistance and tensile strength.
Appearance:White powder,granule,flake,or flocculent Melting point:180-190ºC.
∗ Small particles,small dosage,easy to disperse.
∗ Dissolved in cold water.
∗ Good bonding performance;improve mortar strength.
∗ Prevent mortar from cracking and detaching;increase adhesion strength and smoothness.
∗ Non-toxic,tasteless and environmentally friendly.
