Eco-friendly white glue is a high-performance, non-toxic polyvinyl acetate (PVAc) emulsion adhesive with low volatile organic compounds (VOC), outstanding bonding strength, and wide applicability. It meets green building standards and is ideal for interior decoration, furniture manufacturing, and DIY crafts.
1. Composition and Manufacturing
Eco-friendly white glue primarily consists of a polyvinyl acetate emulsion produced via emulsion polymerization. Common auxiliary ingredients include:
-
Dispersants and thickeners to ensure uniform stability.
-
Preservatives to inhibit microbial growth and extend shelf life.
-
Toughening agents to enhance film flexibility and impact resistance.
Typical production steps:
-
Feed vinyl acetate monomer, water, emulsifier, and initiator into a reactor.
-
Conduct free-radical emulsion polymerization under controlled temperature.
-
Defoam, adjust formulation with additives, and package.
2. Performance Specifications

Selection Tips: Check solid content, VOC level, drying time, and viscosity against project requirements. Look for eco-certifications like GreenGuard or local green building labels.
6. Application Method and Precautions
-
Surface Preparation: Ensure substrates are clean, dry, and free of dust or grease.
-
Glue Application Rate: 150–200 g/m² for wood; adjust lower for paper or fabric.
-
Pressing: Apply uniform pressure for 20–60 minutes; extended curing for high-strength types.
-
Environmental Conditions: Ideal at 5–35 °C with relative humidity below 75%.
-
Storage: Store at 5–35 °C in a cool, dry place. Shelf life is typically 12 months; protect from freezing.
