Note:

1. Component B is a catalyst, easy to be hydrolyzed by moisture, so the lid should be tightly covered after use.

2. Once group A and B are mixed, chemical reaction occurs; Start immediately, the viscosity gradually rises, can not be stopped, in order to avoid waste, should be based on the amount, with the use of with, should be used immediately after the match, without delay.

3. The mix ratio of group A and B is related to the speed of chemical reaction and the performance of the mold. The more B components, the faster the reaction, the higher the strength and hardness of the product, but the toughness decreases. Therefore, weighing requires precision.

4. Before preparation, component A should be stirred up and down evenly, and then weighed.

5, casting method is suitable for relief class, brushing method is suitable for the production of three-dimensional mold. Pouring relief mold should first make the length and width are greater than the original length and width of each 4-6cm frame. The border should be flat and the inside should be smooth. When pouring, place the frame on a clean glass plate and place the elements in the frame, leaving a gap of 2-3cm on each side

There are bubble solutions in the production process:

1.Improve the design of flicking groove and exhaust system

2.Increase the pressure of the press

3.Reduce the amount of release agent, and evenly spray

4.Material controls moisture

5.Try adding some defoamer

6.Use cold runner

7.Vacuum pumping with a vacuum machine, exhaust operation can be added to the mold.
