SUNDY PVA 088-50 With Anti-foam Agent
PVA polymer powder is especially suitable for use as a building mortar additive. When used in conjunction with methyl cellulose ether water-retaining agents, it can improve the flexibility, water retention and adhesion of cement mortar. In addition, the friction of the mortar is reduced, thereby enhancing the work efficiency and quality. (Prevent the cracking and falling off of the plastering layer, increase the adhesion strength and smoothness).
Polyvinyl alcohol (PVA) is a water-soluble Resin made of ethylene by polymerization and alcoholysis. It has unique strong adhesion, film toughness, smoothness, oil resistance, solvent resistance, gas resistance, wear resistance It can also be specially treated to make it water resistant. PVA17-88, 24-88, 80 mesh powder can be directly dissolved in cold water, 120 mesh, 160 mesh can be quickly dissolved in cold water after dry mixing with other powders to improve the properties of building materials.
PVA is a fine-grained polymer, which is easy to disperse in cold water, and can quickly disperse in water. Its aqueous solution has good viscosity stability, which can improve many characteristics of cement mortar, and also has the function of adsorption.
Discription:
Polyvinyl alcohol 2488 is a white or slightly yellow powdery water-soluble polymer. Has good film-forming properties, formingThe film has good adhesion, solvent resistance, abrasion resistance, tensile strength and oxygen barrier properties. also hydrophilic.
There are two functional groups: base and hydrophobic group, so polyvinyl alcohol has the properties of interfacial activity, and can also be used as polymer emulsification, suspension
Protective colloid for float polymerization. Low dissolution temperature, strong freezing resistance, no gel phenomenon; good solution fluidity and stable viscosity; good hygroscopicity, Strong re-viscosity; contains more hydrophobic groups, good affinity and adhesion to hydrophobic materials.
