Why does the more environmentally friendly external release agent, the worse its glossiness?

Most of the environmentally friendly external release agents on the market are semi permanent release agents. I believe everyone can understand what "semi permanent" means. Simply put, it is completely unreasonable to say that a single release agent can make the surface of the product brighter and brighter. The reason why a mold will never have a worse surface effect than a product is the same, because there is a release layer between the mold and the product, which is commonly referred to as a layer of release agent on the mold surface.

Why does the glossiness of fiberglass products decrease with the increase of release agent frequency?

Because in the production process of fiberglass products, unsaturated polyester resin will generate heat after curing, which can push up moisture and incompletely reacted styrene and other raw materials, and retain them between the mold surface and the isolation layer. After a certain period of product molding, styrene also undergoes polymerization reaction, forming a stubborn thin film, which is the main culprit affecting and reducing the surface brightness of the product.
 

What should we do if this situation arises? The editor suggests using mold cleaning agents to clean the mold, which can thoroughly remove such solvent based deposits. Grinding can also be used for treatment, but it can cause certain damage to the mold and easily damage the adhesive layer on the surface of the mold. For these reasons, it is very important to choose high-quality environmentally friendly external release agents and mold cleaning agents. This can not only improve product quality, but also save labor costs and increase production efficiency.
