100-60 Fully Hydrolyzed Polyvinyl Alcohol Used In Painting

Standard Grades

Individual HUAMAO® polyvinyl alcohol grades vary in molecular weight and degree of hydrolysis. Molecular weight is generally expressed in terms of solution viscosity. The viscosities are classified as ultra low, low, medium and high, while degree of hydrolysis is commonly denoted as super, fully, intermediate and partially hydrolyzed. A wide range of standard grades is available.

Customization

HUAMAO® can customize according to customer demand, production of goods.
1. HUAMAO® can customize the packaging according to the customer's requirements.
2. HUAMAO® can process various sizes (mesh 80 100 120 160 etc.).
3. HUAMAO® can produce different physical forms of PVA: flocculent, flaky, powder.
4. HUAMAO® can produce PVA which is the special technical index (alcoholysis degree and viscosity), according to the customer's demand.

Exterior wall coating Not only plays a protective role in the building but also has decoration and beautification function. With the social progress, people's external wall coating requirements are increasingly high, high-performance, multi-functional and water-based environmental protection has become the development direction of external wall coatings.

A kind of inorganic complex is used to modify the intercourse agent, which can make polyvinyl alcohol (PVA) and silica sol produce semi-interpenetrating network connection to form compound glue, select PV silicon residue as main filler and prepare the waterborne coating.
The use of special modified sexual coupling agent (referred to as MC, hereinafter) shielding the polyvinyl alcohol (PVA) on the majority of hydroxyl, and make PVA coating and silica sol occur half interpenetrating network connection, the composite gum has both excellent film-forming properties of PVA, and the water resistance and hardness of silica sol, add the appropriate amount of pigments and fillers and functional materials, adjust the system performance, It can produce a new environment-friendly waterborne exterior wall coating with excellent weather ability, stain resistance, function, and adhesion.

(1) Using polyvinyl alcohol (PVA) and silica Sol as the basic film-forming material, through modification, the formation of the semi-interpenetrating network, the preparation of existing PVA excellent film-forming properties, as well as silica sol coating good water resistance and hardness of the building coating.

(2) The content of PVA and silica Sol in the compound colloid is not very high, so the colloid cost is very low; At the same time, the use of chemical products NAF production of the tail material to fill, not only to treasure, reduce costs, but also improve the physical and chemical properties of the coating.
