Sika's adhesives and sealants are working materials that show good affinity for other surfaces. Their task is to flow as a liquid onto and into the contours of a surface and subsequently transform themselves into a solid compound by developing both a physical and chemical bond with the substrates.
Sika's Marine Adhesive and Sealant Systems can range from fluid to heavy thixotropic, paste-like systems, able to supply low-to-high strength values and able to cure to a highly elastic or rigid bond. The ability of the adhesive or sealant to "wet" a surface is critical in the development of a proper bond; solidification (curing) can take place through a physical or a chemical reaction or both of these at the same time.
By drying off the adhesive |
 |
Loss of solvent or moisture from an open surface and through porous substrates |
e.g. SikaSense or SikaTherm, aqueous or solvent based systems |
By applying a hot, molten adhesive and leaving it to cool |
 |
A molten adhesive is applied to a joint, held in place and left to cool until solid |
e.g. SikaMelt, a hot melt adhesive |
By chemical reaction, using a two- component meter-mixed adhesive |
 |
Two reactive adhesive elements are mixed, applied to a joint, and held in place until handling strength is reached |
e.g. SikaDur, a two-component epoxy based (EP) resin.
SikaFast, a two-component acrylic resin based system or
SikaForce, a two-component polyurethane (PUR) based system
|
By chemical reaction, using a one- component humidity-curing process |
 |
A one-component moisture reactive adhesive, applied to a joint, and held in place until sufficient handling strength is reached |
e.g. Sikaflex, a one-component polyurethane (PUR) based system or
SikaSil, a one-component silicone (SI) based system
|
By chemical reaction, using a one- component vacuum- curing process |
 |
One-component vacuum reaction adhesive requiring absence of oxygen from the joint until curing is complete |
A one-component anaerobic acrylic adhesive e.g. thread lockers |
