A new product featuring a differentiated structural design has recently entered the coating and molding liquid silicone rubber segment. This coating-type liquid silicone rubber, with a two-component 1:1 mixing ratio and a three-layer structural design, has been officially introduced to the market. Specifically developed for silicone leather coating applications, its design concept balances functional division with process convenience .

Three Layers, Each with Its Own Function

The core technical highlight of this product lies in the functional differentiation across its three layers :

• Top Layer: Provides an excellent release effect, ensuring that the coated silicone leather surface remains non-stick and easy to demold.
• Middle Layer: Serves as the core for mechanical strength and flexibility, balancing the material's structural integrity with tactile comfort.
• Bottom Layer: Enhances adhesion to the substrate, addressing the process pain point of coating detachment and peeling.

This synergistic three-layer design achieves a better balance between tactile feel, durability, and processing yield for silicone leather .

Process-Friendly: 1:1 Mixing + Long Working Time

In terms of ease of use, the material features a two-component 1:1 mixing ratio, eliminating complex proportioning calculations. Ordinary workers can be trained to operate it with simple instruction, reducing training costs for manufacturers. After mixing and degassing, the material is ready for coating. It combines high strength with good flowability, making it adaptable to coating substrates of various shapes .

Regarding the working time window, it offers a 48-hour pot life at 25°C, allowing ample flexibility for production line pacing, while rapid curing at elevated temperatures supports different production speeds. It should be noted that contact with amines, sulfur, and tin compounds may inhibit the curing reaction, so related contamination sources must be avoided during production .

Clear Application Scenarios

According to available information, this coating liquid silicone rubber has already been deployed in applications such as release coating, eyeglass nose pads, and handicraft processing . For downstream enterprises involved in silicone leather coating and precision coating processing, this three-layer structured material solution offers a new option for enhancing coating quality and consistency.
