| Basic properties | 1. General appearance transparency
2. General mechanical properties | 1. Good appearance transparency
2. Excellent mechanical properties (tensile, tear resistance, etc.) | 1. Good appearance transparency
2. Completely maintain the mechanical properties of ordinary liquid adhesive |
| Process maturity | a. Primer process:
The primer on the market is easy to hydrolyze and unstable, which requires a storage and use environment. The primer may erode the material and produce imprints (which can be covered by the opacity of the rubber mixture). The primer is micro yellow with the risk of color difference. Primer construction includes coating, spraying, brushing, and other processes—different construction results in different coating uniformity, which may lead to poor local adhesion.
b. The molding process of the rubber mixture is mature. | a. Primer process:
The primer on the market is easy to hydrolyze and unstable, which requires a storage and use environment. The primer may erode the material and produce imprints (the liquid glue has good transparency, which may not cover and make up). The primer is micro yellow with the risk of color difference. Primer construction includes coating, spraying, brushing, and other processes—different construction results in different coating uniformity, which may lead to poor local adhesion.
b. The injection technology of liquid glue is mature. | Stable and reliable |
| Quality stability and environmental protection
| The market is full of all kinds of products, and the quality is different and unstable.
In general, the peroxide system of double pentaerythritol is used to reduce the risk of residual peroxide in products. The primer is generally a solvent type, which affects the working environment of the workshop and needs to be evaluated for occupational hazards in the workplace. | The stability of the primer mainly controls it.
The primer is generally a solvent type, which affects the working environment of the workshop and needs to be evaluated for occupational hazards in the workplace. | The formula is stable and mature.
The risks are reduced in the operation process. |
| Application trend | It belongs to the edge of elimination, mainly in the low-end market. | It is mainly applied by medium-sized customers, which is one of the current mainstream. | It is mainly in the mature application and promotion of supporting the supply chain. |
