Eastman Pvb Polyvinyl Butyral Resin Uses Ceramic

Eastman Pvb Polyvinyl Butyral Resin Uses Ceramic 

Polyvinyl butyral resins has a diverse range of uses. It is valued for its use in high-quality ink, as a primer/binder for paints for coating metals to prevent rust, and as an indispensable binder in the advanced fine ceramics field.

Ability to bond to metal, ceramics and other inorganic materials,Optical clarity in film form,Dissolves in alcohol, mixes with a variety of organic solvents,High compatibility with other resins/plastics, depending on composition

Melt-molding is possible due to thermoplastic processing,Toughness,Cross-linked with phenol resins, epoxy resins and isocyanate through the hydroxyl group,Low environmental impact as a polymer made from carbon, hydrogen and oxygen.

1. PVB RESIN Physical properties:

 

A. The appearance is white and easy to flow granular powder, the density is 0.17-0.4g/cm3, the temperature can be adjusted to minus 60 ° C, the glass transition temperature is 57 ° C, and the softening temperature is 60 ° C -75 ° C.

B. Solubility: PVB is insoluble in water and soluble in various organic solvents such as alcohols, esters and ketones, such as ethanol, phenylacetyl and cyclohexanone. And mixed with a variety of plasticizers such as phthalates, phosphates, fatty acid lipids.

C, has good insulation, weather resistance, water resistance, aging resistance and resistance to inorganic acids and aliphatic hydrocarbons. In addition, polyvinyl butyral is non-toxic, odorless, and non-corrosive.

3.PVB RESIN Application

1). Transparent material: PVB has special bonding and high transparency to inorganic and organic glass. It can be used as a sandwich material for safety glass. 

2). Coating: Because PVB has the characteristics of high bonding strength, cold resistance, oil resistance, wear resistance and corrosion resistance, it is widely used in:

 Wood coating: surface treatment agent for plywood and primer for hard board and insulating board.

 Metallic coating: Used in combination with other natural resins, synthetic resins, and drying oils to improve the impact resistance, flexibility, and adhesion of thermosetting resins.

Metal bottom knee: PVB can be used as a primer for metal materials such as steel, aluminum, galvanized, iron and copper. 

Metal ink: It is mixed with nitrocellulose, maleic acid resin, etc., and is used as a metal ink for an aluminum plate or a copper plate.

Coating of metal box: Applying PVB solution on metal foil (mainly aluminum foil) can improve the strength and moisture resistance of the foil, and can be completely wrapped with heat only for packaging chocolate, biscuits and other foods. 

Concrete coating: When the PVB solution is used as the primer, the durability of the water emulsion paint film can be improved.

Waterproof coating: As a waterproof paint for fabrics, PVB can be used to produce good effects. It can be used to make tents, coats, food bags, raincoats, ponchos, etc.

Leather coating: PVB film exhibits strong elongation at room temperature and maintains this property at low temperatures, so it can be used to prepare a soft and elastic film, which has become a unique property of PVB resin.

Glossy face protection coating: used for varnish, wire paint and other various metal plating surfaces of woodworking crafts.

3). Adhesive: PVB contains hydroxyl, acetyl and aldehyde groups and has high bonding properties, so it can be made into various adhesives:

Bonding of glass: Since PVB has extremely high adhesion, proper elasticity and flexibility, it is used to bond glass.

Bonding of metal: After mixing PVB with phenolic resin, it can be formulated into different grades of acetal phenolic glue, 

Bonding of the enamel coil: The PVB solution is applied to the coil, and the coil can be bonded after heating.

Heat-sealing adhesive: PVB can be mixed with natural resin, synthetic resin and plasticizer, and can be used as a heat-sealable adhesive.

Adhesive for "transfer trademark": PVB can be used as a binder for porcelain "transfer trademark

Bonding film: PVB can be used for heat bonding of cloth to cloth or other materials when combined with other synthetic resins, synthetic rubbers and plasticizers.

Pressure-sensitive adhesive: used as a binder raw material for a pressure-sensitive adhesive tape such as a cellophane tape or a polyethylene tape.

4). Application in fiber processing:

Coating: Apply PVB solution with plasticizer to various textiles to make it waterproof, prevent pollution, etc., and not damage the original feel and style of textiles. 

Fiber treatment agent: PVB aqueous dispersion containing plasticizer, which can be used as cotton fabric treatment agent, anti-shrinkage agent, anti-shock agent and stiffener.

Printing and dyeing of fabric: PVB solution and emulsion can be used for printing and dyeing of fabrics, with good printing and dyeing effect, washing and fading.

Parts: PVB is mixed with synthetic rubber such as butadiene rubber, neoprene, etc., and can be molded into electromechanical parts with high impact and high strength molds, hoses, pipes and bars.

Besides, we also supply Titanium Dioxide , Iron Oxide, Chrome Yellow, Carbon Black Pigment.
