  • the invention relates to non-stick coating material for the metal surface production molds used in industrial manufacturing (for production of polymers, etc.), to be applied before the production stage, just for one time and directly to the mold surface, to ensure the material produced in the mold can easily come-off and be released from the mold without sticking.
  • This invention relates in particular to coating material including methyltrimethoxysilane, tetramethylorthosilicate, acetic acid, 2-methoxy-1 -propanol, titanium dioxide, polytetrafluoroethylene.
  • mold release agent is used in existing applications to enable the produced material to be easily released from the mold. This release agent has to be applied into the mold for each production cycle.
  • high costs and the risks posed for human life are disadvantages of the current method.
  • the release agent is not preferred to be used to remove such risks, the parts produced stick to the metal mold surface, leading to defective production.
  • Multi-layer non-stick coating system and materials coated with it with issue no. TR200906244. Summary of this invention is as follows: "Multi-layer non-stick coating systems or besides, materials coated with these coating systems are provided.
  • Primer of this multi-layer system includes a fluoropolymer copolymer like a fluoropolymer terpolymer, including tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride monomers and these fluoropolymer copolymers are usually called THV.
  • Multi-layer system is characterized with perfect main layer adhesion and release and the primer features perfect primer-main layer and primer-upper layer adhesion.
  • multi-layer system is resistant to release failures on the interface between the bonding and fluoropolymer components of the primer, provides excellent adhesion to smooth main layers and may include a high level of filling material to ensure high damage resistance without compromising the aforementioned advantages.
  • the coating in the mentioned application requires primer application underneath multiple layers. It has also been used in fluoropolymers in lower temperatures to the high melting temperature of PTFE. Besides the foregoing, the application also includes metal kitchen utensils and cooking pots. It has not been applied to industrial mold and currently is not being used in that area. As a result, due to the disadvantages listed above and the inadequacy of existing solutions about this issue, a technical development is required regarding the industrial mold with nonstick surface.
  • This invention relates to non-stick coating material applied to the mold to prevent sticking of the product to the mold surface in metal surface molds which meet the aforementioned requirements, remove all disadvantages and brings additional advantages.

  • Another purpose is coating material to be applied before the production stage, just for one time and directly to the mold surface, to ensure the product in the mold can easily be released from the mold without sticking.
  • Another purpose is increased mold adhesion strength compared to the non-stick coating materials used in the existing method. Thus, it provides the performance to meet industrial requirements.
  • Another similar purpose is increased resistance of the composition including raw materials against chemicals and scratches compared to the coating materials used in the existing method.
  • Another purpose is a coating material applied as a single layer without any need for a primer. Another purpose is the lack of requirement for melting of PTFE during the production method. Successful coating application is possible under the melting temperature of PTFE by prolonging the curing time. Another purpose is ease of application.
  • a non-stick coating material including methyltrimethoxysilane, tetramethylorthosilicate, acetic acid, 2-methoxy-1 -propanol, titanium dioxide, polytetrafluoroethylene for the metal surface production molds used in industrial manufacturing, to be applied directly to the mold surface, to ensure the material produced in the mold can easily be released from the mold without sticking.
