Clear PVAC Emulsion Polyvinyl Acetate Emulsion for Transparent Film Formation on Fiberglass Surfaces

Product Description

Description :

Polyvinyl acetate emulsion is a high - molecular - weight polymer emulsion with water as the dispersing medium. It's mainly prepared via the emulsion polymerisation of vinyl acetate monomers.

Characteristics

Appearance and Physical Form: It's usually a milky - white, uniform emulsion. It's neutral to weakly acidic, with a pH between 4.5 and 6.5. It's non - toxic, odourless, non - corrosive, and not flammable or explosive.
Solubility: It mixes well with water but doesn't mix easily with organic solvents like methanol, ethanol, and acetone.
Viscosity: The viscosity varies widely, generally between 20 and 5000mPa.s. It can be adjusted by adding thickeners or diluents.

Stability: It's stable at pH 3 - 7, tolerating weak acids and alkalis but not strong ones or organic solvents.
Polymerisability: The vinyl acetate monomer has a carbon - carbon double bond, making it easy to undergo free - radical polymerisation to form polyvinyl acetate.
Reactivity: It can undergo addition reactions with halogens and hydrogen halides. It can also be oxidised by strong oxidising agents like acidic potassium permanganate. Its ester groups can hydrolyse under acid/alkali catalysis.

Applications :

Adhesive Field: It's a common adhesive for porous materials like wood, paper, and fibres. It's used in printing, woodworking, construction, leather, cigarette - making, aluminium - foil composites, and sandpaper manufacturing. For example, in woodworking, it can bond items like pencils, crates, plywood, and fibreboard, providing a transparent, aesthetically pleasing bond.
Coating Field: It's a key raw material for interior wall coatings and cast - steel insulation board processing. The coatings have good dispersion, penetration, stain resistance, and renewability, making them more environmentally friendly than paints.
Other Fields: It can be used as a sizing and finishing agent for textiles and for bonding and fixing in medical devices.

Safety

If it comes into contact with the eyes, immediately rinse with clean water for 15 minutes and then seek medical attention. If it comes into contact with the skin, wash with water. If accidentally ingested, rinse the mouth, drink plenty of water, and then seek medical attention.

Storage and handling :

Store in a cool, well - ventilated, dry warehouse. Seal the container. Avoid freezing and sun exposure. Keep away from ignition sources, heat sources, and oxidising agents.

Packaging :

Polyvinyl acetate emulsion can be supplied in 125/250 kg HDPE drums, IBC and bulk tankers.
