Decoration anti-cracking epoxy joint glue

1 Scope

China's national standard for the epoxy resin joint sealant used to prevent cracking in refurbishment work. It specifies the terms and definitions, the product classification and marking, the requirements, the test preparation and test methods, and the inspection rules. The problem it addresses is one that every renovation meets. Where new material joins old - a partition against an existing wall, a plaster patch, a board joint over a repaired substrate - the two move differently as they dry, as the building settles and as the temperature changes, and a crack opens along the line. It reappears through paint, through wallpaper and through skim coat, and it is the most common defect in finished refurbishment work. An epoxy joint sealant works because it is rigid and bonds strongly to both faces: rather than accommodating the movement, as a flexible sealant would, it prevents the two surfaces from moving relative to each other at all. That only works if the bond exceeds the force, which is what the requirements have to guarantee.

This standard specifies the terms and definitions, product classification and marking, requirements, test preparation, and test for the decoration of epoxy resin joint glue for crack prevention. Methods, inspection rules and packaging, labeling, marking, transportation, storage. This standard applies to solvent-free seams for interior decoration consisting of epoxy resin (component A) and amine curing agent (component B). Glue products.
