Solvent-free Laminating Adhesive usually refer to adhesives used in solvent-free compounding processes. Such adhesives do not contain organic solvents and have the advantages of being environmentally friendly, non-toxic, and having low VOC (volatile organic compound) emissions. The following are some of the main types and characteristics of Solvent-free Laminating Adhesive:
1. Main types
Polyurethane Solvent-free Laminating Adhesive
● Polyester polyurethane: has excellent physical properties and chemical stability and is widely used in the compounding of packaging materials.
● Polyether polyurethane: similar to polyester polyurethane, but may differ in certain specific properties, such as hydrolysis resistance.
● Two-component polyurethane compounding agent: consists of two components and needs to be mixed in a certain proportion when used to produce a chemical reaction and cross-linking and curing.
● One-component polyurethane compounding agent: easy to use, no mixing required, but may be limited in performance.
Other types of Solvent-free Laminating Adhesive
Such as epoxy, acrylic, etc., these types of Solvent-free Laminating Adhesive are also used in specific fields, but compared with polyurethane, their market share may be smaller.
2. Characteristics
● Environmental protection: The biggest feature of Solvent-free Laminating Adhesive is environmental protection, does not contain harmful solvents, and reduces pollution and emissions during the production process.
● Strong adhesion: Most Solvent-free Laminating Adhesive have high adhesion, which can ensure a firm bond between different materials.
● Temperature resistance: Some Solvent-free Laminating Adhesive have good high or low temperature resistance, which are suitable for use under different temperature conditions.
● Various curing methods: The curing methods of Solvent-free Laminating Adhesive may include thermosetting, aging, etc., depending on the product formula and process requirements.
3. Application fields
Solvent-free Laminating Adhesive are widely used in the composite process of various materials, including but not limited to:
● Packaging materials: such as aluminum foil, aluminum-plated film and plastic PET composite, used to make food packaging, pharmaceutical packaging, etc.
● Building materials: such as aluminum honeycomb panels, stainless steel plates, color steel plates and other metal plates, as well as other building materials.
● Industrial fields: such as occasions where materials need to be composited in industries such as electronics, automobiles, and aerospace.
In summary, Solvent-free Laminating Adhesive have various types and characteristics and are widely used in various fields. When selecting Solvent-free Laminating Adhesive, it is necessary to comprehensively consider factors such as specific application requirements, material properties, and production process requirements.
