About Polyvinyl Alcohol
PVA (Polyvinyl Alcohol)
PVA is a water-soluble, high molecular polymer with many uses. It has unique strong adhesion, film flexibility, smoothness, oil resistance, solvent resistance, protective colloid properties, gas barrier properties, abrasion resistance and water resistance.
The polyvinyl alcohol powder and other powdered ingredients are fully dispersed through dry mixing and then dissolved with water. At this time, PVA can dissolve without condensing.
It can be used in conjunction with cellulose ethers to improve the flexibility, water retention, viscosity of building materials and glue. To prevent the cracking, shedding and increase the adhesion strength and smoothness of the coating.
Type:
PVA0588, Viscosity 4.6~6, mesh 120, granular
PVA1788, Viscosity 20~26.5, mesh 120, powder or granular
PVA 2488, Viscosity 25~53, mesh 80~160, powder or granular
PVA1799, Viscosity 23~29, granular
Polyvinyl Alcohol as additives is used in cement-based products and glue. Such as cement mortar, thermal insulation mortar, anti-cracking mortar, wall putty powder, paints, construction glue, adhesive etc.
