Sealants. Determination Method of Bond Strength with Metal at Peeling

GOST 21981-76  applies to flexible sealants and establishes a method for determining bond strength when peeling them from a metal.

The essence of the method is to measure the load, causing the exfoliation of the sealant with a metal grid applied to it from a metal surface.
