Chemical resins are used when fastening to concrete and other such substrates, usually when a higher degree of flexibility is required.
The chemical is injected into the hole before the fastener is introduced. As the resin is applied under pressure it automatically finds its way into every surface of the hole. This drives all of the air from the hole, creating a high strength bond when the fastener is inserted.
Resin capsules are a glass resin capsule that is activated by driving a stud against the capsule with a rotary hammer drill which breaks the glass and activates the resin.
