Release agents are the barrier to interpose between mold and laminate in order to avoid cohesion, and irreversible bonding, of the two parts between them.
Generally, they can be divided in four main types: wax based release agents, film-forming, semi-permanent ones and those in film. Films’ release agents have various uses, depending on the need and personal creativity, but we must remember that being films and therefore not able to follow perfectly each type of curved surface, they leave many traces on the final surface. The other three types of release agents have their proper uses, specified within each product’s description. The category composed by semi-permanent release agents, is used in industrial systems for a time saving in large productions. They are also very effective on metallic molds and are defined as semi-permanent because they require a remaking every 50-100 molded. Their installation and periodic remaking are operations that needs care and a perfect surfaces’ cleaning, otherwise you may achieve the opposite effect.
