JHSW8601 Polyurea Waterproof and Anti-Corrosion Coating Successfully Passes Food-Contact Coating Standard Testing

Recently, the JHSW8601 spray-applied polyurea waterproof and anti-corrosion coating, independently developed and produced by Qingdao Polyswell Technology Co., Ltd., has successfully completed sensory properties and physicochemical performance testing in accordance with the requirements of the GB 4806.10-2016 National Food Safety Standard for Food-Contact Coatings and Coating Materials. The test results indicate that all inspection items fully comply with the national food-grade safety standards, confirming the product’s safety for food-contact applications.

Product Overview

JHSW8601 high performance long durability waterproofing and anti-corrosion pure polyurea is the state of the art 100% solids, ultra fast cure, flexible, two component aromatic pure polyurea elastomer.

The system consists of A component, a quasi-prepolymer rich of free NCO, and B component, a mixture of polyetheramines, amine extenders and other additives.

JHSW8601 has great physical property and durability, It can be used for waterproofing and anti-corrosion.

Testing Standards

To ensure the product’s safety in food-related environments, Qingdao Polyswell Technology commissioned an authoritative third-party testing agency to conduct comprehensive testing on the JHSW8601 product, referencing the GB 4806.10-2016 National Food Safety Standard for Food-Contact Coatings and Coating Materials. The testing items included:

Sensory evaluation
Soaking liquid test
Overall migration test
Potassium permanganate consumption
Heavy metals (as lead, Pb)

Test Results

According to the test results, JHSW8601 met all relevant requirements of the GB 4806.10-2016 standard for sensory properties, total migration, potassium permanganate consumption, and heavy metal limits, achieving the required food-grade safety standards.
