Oil-based Release Agent

Oil-based release agent is a chemical specifically used to remove plastic products from molds. It is typically composed of high-viscosity mineral oil, surfactants, additives, and lubricants. Its primary function is to facilitate the removal of molds during the production of plastic products, reducing the chemical and mechanical hazards that workers may face during operation.

Composition and Function

The main components of oil-based release agents include high-viscosity mineral oil, surfactants, additives, and lubricants. The proportions of these components may vary depending on the brand and manufacturer. Its primary role is to form a protective film between the plastic product and the mold, enabling smooth release of the product from the mold, reducing adhesion between the plastic and the mold, thereby minimizing waste caused by mold sticking during plastic molding and improving production efficiency.

Usage and Effects

The typical method of using oil-based release agents involves mixing the release agent with solvents such as dichloromethane, petroleum ether, or 120# gasoline. Before application, the mold must be cleaned thoroughly to ensure it is free of rust and concrete residue. After evenly brushing or spraying, allow the release agent to dry before proceeding with concrete pouring or plastic molding operations.

The effects of oil-based release agents include:

Easy Cleaning: Forms a lubricating film on the mold surface, reducing adhesion between the plastic and the mold, making mold cleaning easier.

Improved Product Quality: Prevents sticking, resulting in better surface quality of plastic products, free from defects and flash.

Increased Production Efficiency: Leaves no residue, requires no lengthy drying process, and enhances production efficiency.

Environmental Friendliness and Safety

Oil-based release agents are generally environmentally friendly and non-toxic, free from CFA, harmless to humans, non-corrosive to products and molds, do not affect secondary processing of products, and leave no oily residue on surfaces. Additionally, oil-based release agents are non-irritating to workers, non-corrosive to reinforced concrete, making them an environmentally friendly type of release agent.
