Expert of Jiangsu Provincial Quality Supervision Bureau: Domestic brands are not lost to foreign brands

Interior wall coatings are usually based on water-based coatings.

"In terms of supervision and spot check indicators, the main problems are scrub resistance and unqualified free formaldehyde.

Originally, as an environmental protection indicator, the free formaldehyde project has a clear limit of 100 mg/kg in the national compulsory standard GB 18582-2008 "Limits of harmful substances in interior decoration materials and interior wall coatings".

Experts from the Jiangsu Provincial Quality Supervision Bureau said that the free formaldehyde in interior wall coatings mainly comes from synthetic resin emulsions and antifungal agents.

Domestic brands are not lost to foreign brands

In terms of project analysis of scrub resistance, “scrub resistance is an important indicator to measure the quality of coatings.

In order to facilitate consumers' choice, the Jiangsu Provincial Quality Supervision Bureau specially conducted a performance comparison analysis on the number of times of washing resistance of 80 representative batches of products, taking into account domestic and foreign brands.

The health of the home environment should pay attention to "APEO"

At the same time, this time, 80 batches of the 141 batches of samples were subject to risk monitoring in accordance with the requirements of the EU REACH Annex 17 alkyl phenol polyoxyethylene ethers (APEO).

　　Experts said that the chemical properties of APEO have good wetting, penetrating, emulsifying, dispersing, solubilizing and washing effects.
