Specialist sealants are designed to provide superior protection and performance for specific applications. These sealants are formulated with unique chemical compositions that make them ideal for use in particular environments, such as high temperatures, fire, marine environments, food and pharmaceutical, military and aviation or exposure to chemicals. 

Fire-resistant sealants are used to prevent the spread of flames and smoke in the event of a fire, high-temperature sealants, on the other hand, can withstand higher temperatures. Specific products are also tested and approved for food and pharmaceutical use (NSF), aviation and military (MIL-SPEC) standards. 

Underwater sealants are specially formulated to provide water resistance in submerged environments. These types of sealants can be used for sealing aquariums, swimming pools, boats or any other application where exposure to water is likely. Specialist sealants come with a variety of benefits depending on their composition and designated use.
