Generic classification of adhesives

In determining the appropriateness of a sealant or caulk for an application, many factors need to be considered. The generic polymer technology, the physical form, sealant classification, specifications and performance properties are all important features of a sealant or caulk. Table 22 outlines some basic performance properties of the sealant types reviewed in this chapter. As seen in Table 22, most of these sealant types are utilized in construction applications. As described earlier in this chapter, sealants and caulks can be classified in low, medium, and high movement categories, and selection is primarily decided on the basis of movement capability, adhesion, life expectancy, and material cost. Table 23 reviews the typical applications for these types of sealants and caulks.
