''Contact adhesives'' form high shear-resistance bonds with a rapid cure time. They are often applied in thin layers for use with [[laminate]]s, such as bonding [[Formica (plastic)|Formica]] to countertops, and in footwear, as in attaching outsoles to uppers. [[Natural rubber]] and [[polychloroprene]] (Neoprene) are commonly used contact adhesives. Both of these elastomers undergo [[strain crystallization]].

Contact adhesives must be applied to both surfaces and allowed some time to dry before the two surfaces are pushed together. Some contact adhesives require as long as 24 hours to dry completely before the surfaces are to be held together.<ref>{{cite web|url=http://www.thistothat.com/glue/contact.shtml|title=Contact Adhesives|website=www.thistothat.com|access-date=25 September 2006|archive-date=12 September 2006|archive-url=https://web.archive.org/web/20060912043858/http://www.thistothat.com/glue/contact.shtml|url-status=live}}</ref> Once the surfaces are pushed together, the bond forms very quickly.<ref>{{cite web| url = http://composite.about.com/library/glossary/c/bldef-c1257.htm| title = Definition of ''contact adhesive'' on About.com| access-date = 25 September 2006| archive-date = 24 October 2006| archive-url = https://web.archive.org/web/20061024171339/http://composite.about.com/library/glossary/c/bldef-c1257.htm| url-status = dead}}</ref> [[Clamp (tool)|Clamps]] are typically not needed due to the rapid bond formation.<ref>{{Cite web |title=Contact Adhesive |url=http://www.woodworkbasics.com/contact-adhesive.html |access-date=4 January 2024 |website=woodworkbasics.com}}</ref>
