1. Component B is a catalyst that is prone to hydrolysis due to moisture, so the lid should be tightly closed after use.
2. Once mixed, groups A and B undergo a chemical reaction; Immediately start, the viscosity gradually increases and cannot be stopped. To avoid waste, it should be used according to the dosage and prepared as needed. After preparation, it should be used immediately without delay.
3. The mix ratio of groups A and B is related to the speed of chemical reactions and the performance of the mold. The more component B, the faster the reaction, the higher the strength and hardness of the product, but the lower the toughness. Therefore, accurate weighing is required.
4. Before preparation, component A should be evenly stirred up and down before weighing.
5. The pouring method is suitable for the production of relief molds, while the brushing method is suitable for the production of three-dimensional molds. For casting relief molds, a frame with a length and width greater than the original length and width of 4-6 cm should be made first. The border should be flat and the inner surface should be smooth. Place the frame on a clean glass plate during pouring, and then place the original component in the frame, leaving a gap of 2-3CM on each side.

Solution for bubbles during the production process:

Design of improved flash grooves and exhaust systems
Increase the pressure of the press
Reduce the amount of release agent and spray evenly
Material control moisture
You can try adding some defoamer
Using a cold runner
By using a vacuum machine for vacuum extraction, exhaust operations can be added to the mold.
