Urea-formaldehyde adhesive
Highlights:
Economical: As a traditional adhesive, it has a clear cost advantage and is suitable for decoration projects with limited budgets.
Easy to operate: Easy to apply and widely used for bonding various types of boards.
Formaldehyde hazard: Long-term release of free formaldehyde affects the health of residents. Even E1-level products need to pay attention to ventilation.
Summary: Urea-formaldehyde glue has occupied a place in the market due to its affordability and ease of use, but the demand for environmental protection upgrades forces it to confront the challenge of formaldehyde release.
Bean Gum
Highlights:
Environmentally friendly and low formaldehyde: Compared to traditional adhesives, the formaldehyde emission is significantly reduced, in line with the concept of green living.
Biodegradability: Biobased materials, natural degradation, contributing to sustainable development.
Shortcomings:
Waterproof performance is limited: It is not suitable for humid environments and thus restricts its application scope.
Poor weather resistance: prone to mold and aging, shortening the product's lifespan.
Summary: Gum arabic has gained popularity due to its environmental-friendly and biodegradable properties, but it needs to overcome the shortcomings of water resistance and weather resistance to expand its application scenarios.
Lignin glue
Highlights:
Water-resistant: Capable of effectively dealing with humid environments, enhancing the durability of the furniture.
Construction is simple: The operation process is relatively straightforward and easy to carry out.
Limitations:
Adhesion is slightly inferior: Compared to high-end adhesives, the adhesion needs to be improved.
Special construction requirements: Some products require complex pre-treatment, which increases the construction difficulty.
Material brittleness: The material becomes brittle after curing, which may affect the toughness of the board.
Summary: Lignin glue demonstrates outstanding water resistance, but it needs to continuously improve in terms of adhesion strength and ease of construction.
MDI
Highlights:
Superior Adhesion: Ensures a seamless connection between the panels, providing outstanding structural strength.
Waterproof excellence: Suitable for high-humidity environments such as kitchens and bathrooms.
Challenges:
Storage and transportation are sensitive: Temperature must be strictly controlled to prevent crystallization which may affect usage.
Condition restrictions: High requirements for storage and transportation environment, resulting in increased costs.
Construction environment requirements: Conducting construction in a closed manner to reduce the release of harmful gases and increase the complexity of the construction process.
Summary: MDI glue, due to its outstanding performance, has become the preferred choice for high-end furniture manufacturing. However, its special requirements also limit its widespread application.
Water-based glue
Highlights:
Ultra-Environmentally Friendly: Free of formaldehyde and benzene, pure as water, creating a healthy home environment.
No odor residue: No odor after construction, friendly to the occupants.
Considerations:
Higher cost: Due to its high-end environmental protection features, the market price is relatively expensive.
Cost-benefit consideration: For consumers who value cost-effectiveness, they may need to weigh the pros and cons.
Summary: Shuixin glue, with its outstanding environmental performance, has become a new market favorite. Although it is expensive, it offers an ideal choice for families seeking a high-quality lifestyle.
