Water-based spray adhesives are more environmentally friendly than oil-based spray adhesives. In a water-based environment, the polymers in the adhesive (vinyl acetate in white glue is a petroleum derivative) are spherical particles with a radius generally between 0.5 and 5 micrometers. Water-based spray adhesives achieve bonding through the tensile force between polymers. In the adhesive solution, water acts as a carrier for the high polymers, carrying the polymers slowly into the material's structure.

When the water in the water-based spray adhesive evaporates, the polymers in the adhesive bind the two objects together tightly through mutual tensile force. In the use of adhesives, excessive adhesive causes the polymers to crowd together, reducing the tensile force between them. The polymers become crowded, preventing the formation of strong attractive forces.

Simultaneously, the water between the polymers does not easily evaporate, which is why in the bonding process, "the thicker the adhesive film, the poorer the bonding effect." When too much water-based spray adhesive is used, the adhesive acts as a "filler" rather than an adhesive. The bonding between objects does not depend on the cohesive force of the adhesive, but on the 'cohesive force' of the water-based spray adhesive.

I. Characteristics of Water-Based Spray Adhesives:

1. Odorless and Non-Polluting: Lacks the pungent odor of solvent-based spray adhesives;

2. No Organic Solvents: Uses ordinary tap water as a solvent;

3. Non-Volatile Substances: Zero VOCs, because "Deli-Eco-Friendly Water-Based Spray Adhesive" is diluted with "water," so it contains no volatile organic solvents;

4. Non-Toxic: Both water and water-based synthetic resins are non-toxic, so "Deli-Eco-Friendly Water-Based Spray Adhesive" is non-toxic;

5. Economical: More economical than solvent-based spray adhesives of equal weight. Based on customer usage data, the spray area of "Deli-Eco-Friendly Water-Based Spray Adhesive" can reach more than three times that of solvent-based spray adhesives (Note: This is related to actual operation and spray gun equipment), truly achieving both "environmental protection and economy";

6. High Solid Content: The solid content of "Deli-Eco-Friendly Water-Based Spray Adhesive" is above 43%, so it does not need to be sprayed thickly to achieve good results;

7. Long Bonding Time: Can be bonded within 30 minutes after drying;

8. Environmentally Friendly and High-End: A good choice for high-end furniture products.

II. Water-Based Spray Adhesive Technology

1. Water-based spray adhesive technology directly uses thermoplastic polymer composite solvent-based adhesives, adding unique enhancers, modifiers, and related auxiliaries. The production process is simple, requiring no heating. At normal temperature and pressure, mixing and stirring for about 3 hours can produce the product.

2. The product raw materials are non-toxic and sold to chemical markets worldwide. The production process has no "three wastes" emissions. The technical data provides detailed raw material properties and manufacturers.

3. The product is a single-component adhesive, free of harmful solvents such as benzene, toluene, and xylene, making it convenient and safe to use. The shelf life exceeds 1 year.

4. The product has a low odor, dries quickly (bonding within 1-3 minutes), has good sprayability, good initial adhesion, is impact-resistant, has high strength, and is suitable for assembly line production; after curing, it is characterized by temperature resistance, cold resistance, and water resistance, with good overall performance.
