Different Types of Mold Release Agents?

There are many types of release agents available and they all have their own attributes and uses. The important thing is to know when to use each of these mold release agents to guarantee the best outcome. Having professional guidance in this process is also going to be very useful.

  • Sacrificial mold release agent

This is not the most popular type of mold release agent because it needs to be applied several times before every molding operation cycle. You could say that this is the least popular and used type of molding agent when you want to have long-lasting coatings.

  • Solvent-based mold release agent

This is a great type of coating due to how fast it dries up and this makes it extremely practical. The biggest issue with this type of coating is that it contains a lot of hazardous ingredients and this makes it extremely toxic, bot to mention that it is also very flammable, so it does pose many risks.

  • Water-based mold release agents

In contrast with solvent-based molding agents, the water-based release is going to take much loge to dry up, but the health hazards are much lower and this makes it the least toxic molding agent that can be used for any kind of purpose.

  • Semi-permanent mold release agent

There is no way to measure how many releases will be possible before you need to apply this mold release agent again, but it does provide a very reliable solution that will help you avoid having to apply the agent again and again for every single cycle you do when molding.
