A solved-based adhesive, often referred to as a solvent-based adhesive, is a type of adhesive that uses a solvent or liquid substance to create a bond between surfaces. These adhesives typically consist of a polymer dissolved in a solvent. When the adhesive is applied, the solvent evaporates, leaving behind the adhesive material that forms the bond between the surfaces.
These adhesives can have strong bonding properties and are used in various applications such as
mattress, furniture, woodworking, automotive assembly, and some types of construction. They can
bond a wide range of materials, including foam, felt, metals, plastics, and wood.
Their effectiveness depends on factors such as the type of solvent used, the surface materials being
bonded, and the conditions under which the adhesive is applied and allowed to dry.
Solvent-based adhesives are a diverse category, encompassing various types based on the specific
polymers and solvents used. Here are some key aspects to consider:
Types of Polymers in Solvent-Based Adhesives:

1) Rubber-Based Adhesives: These use natural or synthetic rubber polymers dissolved in solvents.
They offer flexibility and are commonly used in tapes, labels, and some bonding applications.
2) Acrylic-Based Adhesives: Acrylic polymers dissolved in solvents form adhesives known for their
weather resistance, durability, and versatility. They bond well with a wide range of materials.
3) Polyurethane-Based Adhesives: These adhesives, derived from polyurethane polymers
dissolved in solvents, offer high strength and flexibility. They are used in various industries,
including automotive and construction.

Solvents Used:

– Common Solvents: Solvents such as toluene, acetone, ethyl acetate, and methyl ethyl ketone
(MEK) are often used. Each solvent has its own characteristics affecting drying time, bonding
strength, and application properties.

– VOC Considerations: Solvent-based adhesives can emit volatile organic compounds (VOCs)
during application and drying. VOC emissions have environmental and health implications,
leading to regulations promoting low-VOC or VOC-free alternatives. Please check more
environmentally friendly and low VOC products of Apex Adhesives both in liquid and spray form.

Applications:

– Industrial Use: Solvent-based adhesives are used extensively in industrial applications due to
their strong bonding properties and versatility in bonding various materials like metals, plastics,
and wood.
– Assembly and Manufacturing: They find use in automotive assembly, furniture making,
footwear manufacturing, and other industries where strong and durable bonds are required.
Considerations and Challenges:
– Ventilation and Safety: Solvent-based adhesives require proper ventilation during application
due to the release of fumes. Safety precautions, including protective gear, are essential when
working with these adhesives.
– Drying Time and Conditions: Drying time can vary based on the type of solvent and
environmental conditions.
