Uses as coatings
Coating for lumber:
The surface-finishing agent for glued boards, substratum coatings for hard boards and insulating materials.
Coating for metals:
Mixed with other natural resins, synthetic resins and drying oil, it can better the resistance to impact, flexibility and bond ability of thermoset resins.
Priming paint for metals:
PVB resin has a very strong adhesiveness to metals, and a good bondability to surface coatings. It can be used as a priming paint for metallic materials, such as steel, aluminium, galvanized iron, copper and so on. It is widely exploited in boats and ships, bridges, aircrafts and electron devices, etc.
PVB liquor can be used as substratum coating; the durability of water emulsion coating film can be improved.
As a waterproof coating, good result can be achieved after PVB is added, and it can be used for making tents, overcoats, food bags, etc.
Protective coating for gloss surfaces:
It is used as varnish for wooden handicrafts, paint for wires and other metal plating surfaces.
Coating for leather:
The thin film of PVB shows its very strong extensibility at normal temperature, and it can also maintain this property at low temperature. As a result, it can be used to produce soft and elastic leather films for its distinctive character.
Coating for vacuum vapor deposition:
PVB liquor can be adhesive to the surfaces of plastic, paper and metals. It can be used for vacuum vapor deposition, for instance, the adhesive for vacuum aluminum plating and the coating for its processing surface.
Coating for metal foil:
PVB liquor improves the strength and moisture resistance of metal foil, and enables a completely closed wrapping heat sealing. This use is applied to the package of foodstuff, such as chocolate, biscuits, and automatic packing of medicine and camera attachments, etc.
Uses as Adhesives
Adhesive to enamel-insulated coils of wire:
Coat PVB liquor on the coils, heat it, and the coils can be adhered.
Adhesive to metals:
When PVB is mixed with phenolic resin, it can be made up into acetal phenolic glue of different specifications and used to adhere various metals. Coat the liquor on the surfaces of metals, and after it vaporizes, the coated metals are pressed heat.
Adhesive to glass:
PVB resin has a very high adhesive force. It is used to adhere glass for its moderate elasticity and softness.
Adhesive for "Transfer Printing Trademarks":
PVB can be used as the adhesive agent of "Transfer Printing Trademarks" for porcelains. For instance, "Pattern Papers for Porcelains" has become one of its important uses. In addition, it can also be used as "Transfer Printing Trademarks" in textile products.
It is used as raw material of pressure-sensitive adhesive tapes, such as the adhesive tape for glass paper, polyethylene adhesive tape etc.
Adhesive for heat sealing:
PVB can be mixed with natural resins, synthetic resins and plasticizing agent and used as adhesive for heat sealing.
Film adhesive bond:
PVB is mixed with other synthetic resins, synthetic rubber and plasticizing agent, then it can be used to adhere cloths or other materials by heating.
Other uses for PVB
Application in fiber processing
Coat PVB liquor added in with plasticizing agent on textile products, and the goods are awarded the properties of water-proofness and resistance to soiling, etc., and it won't destroy the original feel and style. The processing result can be improved by adding cross-linking resin and curing agent in, etc. PVB emulsion can also be processed in this way.
Dyeing and printing of clothes:
Both PVB liquor and emulsion can be used for dyeing and printing of cloths. It is good in washing resistance and non-discoloration. The abrasion-proofness and pliability of cloths can be improved by finishing with other resins.
Glass fiber reinforced plastic and laminated materials:
PVB can be dissolved in the mixture with phenolic resin, in which alkali free glass cloth is immersed. Cloths of this kind can be made into glass parts and better the performances of glass fiber reinforced plastic. It is extensively employed in machinery, instrument and meter industries.
