Basic Introduction
White latex/polyvinyl acetate adhesive
Synthesis of vinyl acetate from acetic acid and ethylene
It can be cured at room temperature, with fast curing and high adhesive strength. The adhesive layer has good toughness and durability, and is not prone to aging
Product features
This product is a water-soluble adhesive, which is a thermoplastic adhesive made by polymerization reaction of vinyl acetate monomer under the action of an initiator. usually
It is called white emulsion or PVAC lotion for short, and its chemical name is polyvinyl acetate adhesive. It is a thick, milky white liquid formed by synthesizing vinyl acetate from acetic acid and ethylene, adding titanium dioxide (low-grade powders such as light calcium, talcum powder, etc.), and then polymerizing through lotion.
Product Usage
It can be widely used for adhesive paper products (wallpaper), as well as for waterproof coatings and adhesives for wood. Adhesion of wooden materials. It uses water as a dispersant, which is safe, non-toxic, non flammable, and easy to clean. It solidifies at room temperature and has good adhesion to wood, paper, and fabrics. The bonding strength is high, and the cured adhesive layer is colorless and transparent, with good toughness, and does not pollute the bonded material; The lotion has good stability, and the storage period can reach more than half a year. Therefore, it is widely used in printing, binding, and furniture manufacturing, as an adhesive for paper, wood, cloth, leather, ceramics, etc. It can also be used as a modifier for adhesives such as phenolic resin and urea formaldehyde resin, and is used in the manufacturing of polyvinyl acetate latex paint, etc.
