KingSeal CR25 is a closed cell polyethylene foam cord, non- absorbent and rot proof. KingSeal CR25 holds in position between both sides of the joint to help with tooling of the sealant and improve sealant contact with joint side to facilitate good adhesion.
Applications
KingSeal CR25 enables the correct width to depth ratio of the sealing slot to be maintained and provides a firm backing for the sealant to be tooled
The use of KingSeal CR25 will also act as a bond breaker at the base of the joint thus preventing three sided adhesion and the accompanying additional stress during joint movement
Advantages
Rot proof and non-absorbent
Available in different sizes
Readily compressible
Acts as bond breaker and minimizing strain for joint sealants
