Q: How to choose resin mold release agent?

Answer:Resin molds can generally be divided into two types, one is rigid, such as fiberglass, epoxy resin, or other thermosetting resins. Another type is softness, such as silicone, rubber, and plastic, which can be used when selecting Release agent At that time, there were too many types of release agents. How to choose suitable materials such as silicon, mineral oil, solid, emulsified oil, rapeseed oil, fluorine, powder, etc.? Generally, they can be classified.

Such as oil-based, water-based, and solid (including paste like), because resin molds have good surface density, smooth surface, and few capillary pores, they are generally polished and surface treated. If water-based release agents are chosen, it is easy to cause difficulty in volatilization, difficult to spray or apply, forming a lotus leaf like flow hanging, and the baking operation is also more complicated. Therefore, for resin mold forming, volatile release agents or paste wax are mostly used. Because volatile release agents have good leveling, fast volatilization, good film formation, and excellent demolding performance, solvent based volatile release agents are mostly used in resin mold production processes.
