rtv-2 liquid silicone rubber not curing the reason

Users sometimes use liquid silicone curing problems encountered, now our summarizes five kinds of the cause of the rtv-2 liquid silicone not curing and their solutions, we hope to help.

1. A curing agent or too little of the curing agent will affect the cured silicone.

According to the provisions of the curing agent is added, and should see clear instruction is the proportions of the volume or weight.

2. Different types of curing agents can’t mix, add molding glue exposure to tin ingredients in the condensation silicone will not respond.

With the corresponding models of the curing agent. Operating tools are classified, do not mix. If you are operating plus molding silicone, do not come into contact with condensation products.

3. Silicone and curing agent do not stir evenly.

Silicone and curing agent operation to fully stir well.

4. Incomplete cure (not dry) in the contact surface occurs only master, the other parts of the intact curing.

Marked on the surface of the master mold with a thin insulating film to prevent the female mold is not conducive to the curable composition in contact with the silicone mold.

5. Temperature is too low can cause no cure, the operating temperature is lower than silicone does not react with the curing agent at 10℃.

When the temperature at 20-30 ℃ is the ideal temperature to cure silicone mold.

About artificial culture stone-colored silicone molds difficult problem

Currently the production of artificial culture stone steps mainly in ten steps, namely: model sculpture model processing → Templates → production → Templates → Partition → model paste brushing silicone mold release preparations → first layer of silicone brush silicone perfusion → off mode. According to the above ten steps, we can see that the production of artificial culture stone mold is the most important use of templates.
