PVA adhesive, or polyvinyl acetate adhesive, is a type of synthetic polymer glue commonly used in woodworking, crafts, and paper projects. It is known for its strong bonding properties and versatility, making it suitable for various materials like wood, paper, and fabric. PVA adhesive dries clear and is water-soluble when wet, allowing for easy cleanup. This adhesive is available in different formulations, including white and yellow types, with the yellow version often providing a stronger bond for outdoor use. PVA adhesives are non-toxic and safe for use in schools and homes, making them a popular choice for both professionals and DIY enthusiasts.
