What are the advantages and disadvantages of those different types of mold protectants?

Oil-based mold protectants:

• Oil-based mold protectants are fairly fluid and are therefore able to creep into the tiniest spaces that are most difficult to access, such as recesses and undercuts.
• Oil-based anticorrosion agents dispel moisture and form a temporary protective layer that can last for several months.
• However, an oil-based anticorrosion agent is sensitive to touch and can be wiped away during handling, leaving unprotected areas more likely to rust.
• Oil-based mold protectants produce oil marks on transparent and optical parts if the mold is not properly cleaned before production restart.

Wax-based mold protectants:

• Wax-based mold protectants provide a consistent and longlasting protective layer and do not creep. Also, the wax-based protection film covering the surface of the tool remains intact even if swept over with a finger.
• Wax-based anticorrosion agents protect surfaces considerably longer than oil-based agents because they form an even and dry protection film on the surface without any dripping or creeping that cannot be wiped off by touching it.
• Wax-based mold protectants produce lower must emissions when applied, leading to a cleaner working environment.
• Also, wax-based anticorrosion agents are much easier to remove, since they melt at normal processing temperatures and are removed during the course of regular demolding. A separate cleaning procedure — as required by conventional oil-based products — is not necessary. This leads to a smoother and faster production process.
• However, in case the surface is not completely dry, waxbased anticorrosion agents may cover remaining moisture like a blanket, not allowing the moisture to evaporate or dry-off and thereby causing local corrosion. Therefore, it is highly important that the surface is dry before applying the wax-based anticorrosion agent.
