CP-30 LO Child-Perm® Coating

Product Description:

CP-30 LO Child-Perm® Coating is an extremely effective vapor barrier coating for all low temperature applications. In the wet state, it has an unusual consistency which allows it to be buttered-on in relatively heavy films, or it can be brushed out into thin films. It is made with an elastomeric resin which yields a tough, yet flexible, dry film with excellent adhesive properties.
