Which Type of Mold Release Agent Is Proper For You?

high quality mold release agent
SAKURAI high tech formula mold release products provide good lubrication and excellent in demoulding with smooth film-forming.

The mold release agent is a chemical used to prevent other materials from bonding to surfaces. It can provide a solution in processes involving mold release, metal die-cast release, plastic release, adhesive release, and tire and PU foam release. It is particularly crucial for the user to understand what types of mold release agents are compatible with the various production processes. SAKURAI release agents are divided into 4 categories: Foundry casting release agent, PU release agent, FRP composite release agent and Rubber plastic release agent.

 How to Choose Right Mold Release Agent

Crucial criteria for each release agent to meet is the following:

  • Excellent in lubrication and release performance
  • Good workability for after-processing
  • Minimal mold build-up
  • Lower scrap rates in the molding process to increase productivity


There are different types of mold release agents, and we should select proper one matching materials for individual products. Take the selection of the FRP mold release agent as an example. For FRP products, the release agent is an essential auxiliary material for every type molding process, no matter external or internal release. The external release agent is to prevent molding products stick to the mold, a layer of thin-film formed between the products and the mold so that molded products can easily release from the mold, and ensure the surface of the product and the mold in perfect condition. Internal mold release is a compound which melting point is lower than the molding temperature. When it is added to the resin, it is compatible with the liquid resin. At a certain temperature, it exudes from the resin matrix to form an isolation film between the mold and the product. The selection of FRP release agent must meet the following conditions:

(1) Mold materials, resin types and curing conditions

(2) Molding cycle and molding time

(3) The film is uniform, smooth and less adhesion to the resin

(4) Do not corrode the mold, do not affect the resin curing
