What is the tensile bonding strength of Gaoseil products? Does it comply with national product stand

Publisher:Gaoseal       time:2026-02-06

The specific value of the tensile bonding strength of Gaoseil sealant products may vary depending on the product type (such as structural adhesive, weather resistant adhesive, etc.). But generally speaking, its qualified products need to meet or even exceed the corresponding national product standards.

The national product standard GB 16776-2005 (structural adhesive) needs to meet the following parameter indicators:


project

indicator

sagging

Vertical placement,mm

≤ 3

horizontally placed

non-deforming

extrudability,s

≤ 10

Surface drying time,h

≤ 3

hardness Shore A
