What is pva glue?

PVA Glue: A Versatile Adhesive

PVA glue, also known as polyvinyl acetate glue, is a widely used synthetic adhesive. It's popular due to its ease of use, non-toxicity, and affordability.

Key Characteristics:

• Composition: It's an emulsion of polyvinyl acetate in water. The "PVA" stands for polyvinyl%20acetate.
• Appearance: Typically white in color, but dries clear.
• Application: Applied in liquid form and sets as the water evaporates.
• Bonding: It forms strong bonds with porous materials, such as wood, paper, and fabric.

Advantages:

• Non-toxic: Generally considered safe for use by children, though ingestion is not recommended.
• Easy to use: Simple application and clean-up with water.
• Affordable: Readily available and inexpensive.
• Dries clear: Minimizes visible glue lines.

Disadvantages:

• Limited water resistance: Bonds can weaken or fail in wet conditions.
• Not suitable for all materials: Doesn't bond well with non-porous surfaces like metal or glass without special formulations.
• Drying time: Requires time for the water to evaporate and the glue to set.
• Can be brittle: Dried PVA can be brittle in some applications, leading to cracking.

Uses:

• Woodworking: For joining wood components.
• Papercraft: In scrapbooking, card making, and other paper projects.
• Bookbinding: For adhering pages and covers.
• General crafts: For various art and craft projects.

Types:

• White Glue: The standard, general-purpose PVA glue.
• Yellow Glue (Carpenter's Glue): A stronger PVA glue formulated for woodworking.
• School Glue: Designed for children's use, with emphasis on safety and washability.
