Water-based mold release agent are typically complex in their composition. Because of this, it is tricky to make them.
It is less stable, which is why it is more challenging to form the correct film on the mold surface. Note that this film refers to the barrier on the mold surface that prevents sticking.
Moreover, water-based release agent has shorter shelf lives. Since it contains water, there is a significant possibility of bacterial growth. As a result, product quality tends to deteriorate over time.
A water-based agent may not provide the same level of performance as other agents. It also performs poorly in extreme heat conditions.
A water-based mold release agent is not compatible with various mold materials. Besides, it takes a longer drying time.
What is Solvent-Based Mold Release Agent?
A Solvent-based mold release agent uses petroleum refining as the primary carrier. It features active elements that easily separate the mold from the molded parts. These solvents are typically derived from hydrocarbons or alcohols. When you spray the agent, it evaporates immediately. Later, it forms a thin layer on the surface, acting as a barrier.
The agent allows the smooth release of every product and protects them from wear and damage. It offers compatible power efficiency for release and rapid drying. You can apply it in areas with high humidity or short production cycles.
Solvent-based release agent is ideal for many uses. You can think of automotive, electronics, and aerospace. Regarding materials, solvent-based release agents are ideal for use with rubber, plastic, and ceramics. It is also suitable for use in the paint industry.
One of the most crucial reasons people choose it is its fast-drying time. It can also provide an excellent surface finish. For complex molding, this release agent works exceptionally well. Thus, it is widely used for small and complex shapes of molded parts.
