New Spray Polyurea Technology - - Introduction to HT3S Technology

　　The application fields of polyurea coatings are constantly expanding, which is obvious to the industry. However, coating shedding problems frequently occur in actual engineering, which has always plagued coating manufacturers, anti-corrosion construction enterprises, and end users. In particular, it causes economic losses to construction enterprises and affects the production of end users.

　　Yantai Huate Polyurethane Co., Ltd., as a supplier of polyurea coatings and polyurea technology, continuously researches and develops to improve the performance of polyurea coatings, reduce the difficulty of construction, and eliminate coating shedding problems that construction enterprises are particularly concerned about, giving full play to its professional advantages. Aiming at the chemical composition and molecular structure characteristics of polyurea coatings, it has developed the PRIMER-3S series of special polyurea primers, achieving a breakthrough in construction technology - HT3S technology. Practical applications have shown that even at an ambient temperature of -10°C, there will be no coating shedding problems.

Comparison of the new technology with traditional construction technologies is as follows:

HT3S New Technology Requirements: 
　　1. Remove loose rust from the steel plate. 
　　2. Apply PRIMER3S-M primer. Spray polyurea after 10 minutes. 
　　3. Open time: 16 hours. 
　　4. Substrate temperature: Construction is possible above -5°C.

Traditional Construction Technology Requirements: 
　　1. Steel plate shot blasting derusting to grade 2.5 or above. 
　　2. Apply polyurea primer; spray polyurea after 3 hours. 
　　3. Open time: 8 hours. 
　　4. Substrate temperature: Construction is possible above 10°C.
