Adhesives & Sealants

Adhesives & Sealants

Bonding for life

Numerous products encountered in everyday life would be unthinkable without the use of adhesives and sealants. 
Adhesives, which are stronger, bind surfaces together, while sealants are used to make materials such as concrete air- and water-tight and are frequently applied on the exterior walls of buildings, for example. 
Adhesives have the ability to bind different materials together and to distribute stress more efficiently across joints. They are easily applied and allow increased design flexibility over other binding systems.

Polymer Stabilizers help to prevent discoloration and loss of adhesive properties

Adhesives and sealants are widely used in numerous industries, including automotive, construction/building, electronics, packaging, graphic arts and medicine. The aerospace industry was quick to promote the use of adhesives as a result of their advantages over welding and bolting, for example. They are now used increasingly to join interior and exterior parts of water and ground vehicles as well as airplanes. In construction, adhesives prevent loosening of screws, as well as oxidation and corrosion, for example, on pipes and other items. In the electronics field, adhesives bond and encapsulate components on printed circuit boards, for example. Adhesives are suitable for many packaging applications, including label glues and closure systems. The graphic arts sector uses adhesives for print lamination, book binding, and padding compounds. In medicine, they are used for all kinds of equipment, including blood bags and respirators, as well as for dressings, denture fixation and much more. Adhesives can be damaged either at the edges or all over if the substrates are permeable to light.

SONGWON develops, manufactures and markets antioxidants and light stabilizers that prolong the shelf life and enhance the properties of adhesives. SONGWON’s linear polyurethane solutions are designed for adhesive layers in synthetic leather and flexible packaging, and as ink binders for printing on packaging. SONGWON also manufactures hardeners and accelerators for adhesive systems.
