Comparison Between Solvent-Based and Water-Based Adhesives

Below is a detailed comparison between solvent-based adhesives and water-based adhesives, evaluating their chemical composition, consumption, efficiency, and application process.

---

1. Chemical Composition Comparison

Criteria	Solvent-Based Adhesive	Water-Based Adhesive
Solid Content (Dry Content)	15-18%	50-55%
Volatile Content	85-82%	45-50%
Consumption in Application	150-200 g/m² (depends on material)	35-55 g/m² (depends on material)
Overall Usage (Medium-Sized Leather Goods Factory)	100 cans/month (15 kg each) → 1,500 kg/month	40 boxes/month (10 kg each) → 400 kg/month

📌 Key Insights:

• Water-based adhesives have a higher solid content, leading to lower consumption compared to solvent-based adhesives.
• Water-based adhesives require significantly less material (400 kg/month vs. 1,500 kg/month), resulting in substantial cost savings.

2. Application Process & Tools Comparison

Criteria	Solvent-Based Adhesive	Water-Based Adhesive
Spray Application	❌ Not Supported	✅ Supported
Frequent Refilling Needed	✅ Yes (Frequent)	❌ No
Disposability of Tools (Brushes, Bottles, etc.)	✅ Yes	❌ No

📌 Key Insights:

• Water-based adhesives support spray application, allowing better automation and precise glue control.
• No frequent refilling is needed for water-based adhesives, reducing downtime in production.
• Solvent-based adhesives require disposable tools, leading to higher costs and waste.

Conclusion: Water-Based Adhesives Are the Optimal Choice

🔥 Key Benefits of Water-Based Adhesives:
✅ Lower consumption, reducing adhesive use by up to 73% (400 kg/month vs. 1,500 kg/month).
✅ Safer & eco-friendly, with fewer VOC emissions, improving workplace safety and environmental sustainability.
✅ Compatible with spray application, increasing production efficiency.
✅ No frequent refilling needed, minimizing workflow interruptions.
✅ Reduces disposable tool costs, eliminating brushes and single-use containers.

🎯 Water-based adhesives are not only an environmentally friendly solution but also help businesses reduce costs and enhance manufacturing efficiency. 🚀
