Because polyurea seam cosmetics have excellent characteristics such as yellowing resistance, weather resistance, and strong adhesion, the seam cosmetics industry and the market have gradually gained awareness of polyurea , and many owners will take the initiative to propose the need for "polyurea seam cosmetics".
Seeing that consumers' demand increases, many merchants are targeting this golden opportunity and launching polyurea sewing agents, but do you know? Although both are polyurea sewing agents, the raw materials are divided into "100% all polyurea" and "semi-polyurea". Many manufacturers use the name of "polyurea" and mark the price of all polyurea, but use semi-polyurea or other materials!
First of all, let me give you some insight into the difference between whole polyurea and semi-polyurea:
From the perspective of chemical composition, semi-polyurea contains catalysts and other solvents, while whole polyurea does not. Therefore, the catalyst failure occurs in semi-polyurea, and its durability is not as good as that of all-polyurea, and the raw materials are substitutable.
Relatively speaking, semi-polyurea has low production costs and is cheaper, while all-polyurea has higher requirements in production process, production cost, usage performance, and storage methods.
So, when purchasing polyurea sewing agent, how can distinguish between whole polyurea and semi-polyurea so as not to get stuck?
1. Look at the packaging
semi-polyurea sewing agent is generally closed and stored. If you unscrew the bottle cap, you can directly see the sewing agent;
full polyurea sewing agent is easy to cure when exposed to air, so it needs to be sealed and stored on a double layer. The bottle body of 100% pure polyurea sewing agent is completely sealed and needs to be opened with a tool knife or scissor.
2. Smell the smell
semi-polyurea sewing agent has a strong smell and is poor in environmental protection;
all-polyurea sewing agent has no smell, and will not produce black smoke and dust after ignition, and is more environmentally friendly.
In addition to the intuitive comparison of the above two points, the bigger difference between all polyurea and semi-polyurea seam beauty agent is in the seam beauty quality!
For example, the Shanghai Pioneer Sewing Agent with 100% Aspen Polyurea formula is used. The production process strictly controls the Aspen Polyurea CECS standard. All indicators have passed the national inspection test, and have excellent performance in adhesion and flexibility.
The raw material formula of Hujia Pioneer is solid and does not add water. Each bottle has an exclusive ID since its introduction, one bottle, one code, and enter the online traceability system . The quality guarantee is 20 to 30 years of yellowing resistance.
Each Hujia Pioneer polyurea sewing agent has a "id card" that can trace where the sewing agent comes from, construction details (construction location, quantity and color used, and construction personnel information). For consumers to trace the source with confidence and enjoy quality assurance services.
Therefore, when you choose polyurea sewing agent, you should choose all polyurea. Among all polyurea, you must identify the Shanghai Pioneer Ashen Polyurea!
