Adhesives are substances that join materials together by creating a strong connection between their surfaces. They are also known as glues or bonding agents. Adhesives work by forming an intimate molecular or chemical bond between the adhesive and the substrate, resulting in a cohesive and durable attachment.
A sealant is a material that effectively seals by conforming to the shape of a sealing cover, remaining non-flowing. It employs a polymer matrix to safeguard against the intrusion of external impurities and prevent leaks within various machinery's static joints.
Usually, it uses polymer materials with things like asphalt, resins, and fillers such as talc powder and carbon black. This mixture is enhanced with additives like plasticizers and curing agents. Sealants offer functions such as leak prevention, waterproofing, vibration resistance, sound and heat insulation.
There are many kinds of adhesives, according to the source of materials can be divided into natural adhesives and synthetic adhesives. Natural adhesives come from natural things like starch, protein, rosin, and other biological adhesives. Mineral adhesives like asphalt are also natural. Synthetic adhesives are made from synthetic substances like water glass, synthetic resins, and synthetic rubber.
According to the characteristics of use, it can be divided into water-soluble adhesive, hot melt adhesive, solvent adhesive, emulsion adhesive and solvent-free liquid adhesive. .
There are two types of adhesive: industrial and agricultural/forestry. Industrial adhesive is used for printing, packaging, and bonding furniture. Agricultural/forestry adhesive is used for greening slopes and improving soil structure.
Sealant can be divided into two categories: bonded type and non-bonded type. There are different types of bonding and non-bonding. The bonding type includes elastic, hot melt, and anaerobic. The non-bonding type includes dry fixation, dry exfoliation, semi-dry viscoelastic, and non-dry adhesion.
Adhesives and sealants products play a pivotal role in a multitude of industries and applications, serving as essential tools for joining, bonding, and sealing materials. Adhesives create strong connections between surfaces, eliminating the need for mechanical fasteners and enabling streamlined designs. They find extensive application in manufacturing, construction, electronics, automotive, and consumer goods production. Adhesives bond a wide range of materials, including metals, plastics, ceramics, and composites, providing versatility and enabling innovative solutions.
Sealants, on the other hand, focus on creating airtight and watertight barriers, preventing the ingress of moisture, dust, or other contaminants. They are commonly used in construction, cars, and planes. They are used to seal gaps, joints, and seams. This helps to make them stronger and keep them intact.
The diverse range of adhesives and sealants products caters to specific needs across various sectors. They have epoxy adhesives for strong bonding, silicone sealants for flexible sealing, and polyurethane adhesives and sealants for various uses.
Adhesives and sealants are used in manufacturing and everyday life. They create strong bonds and effective seals. They make things look good and work well.
