According to GlobalData’s company profile on Lion, opthalmic lenses 3D Printing was a key innovation area identified from patents. Lion's grant share as of June 2023 was 1%. Grant share is based on the ratio of number of grants to total number of patents.
A recently filed patent (Publication Number: US20230203279A1) describes an adhesion preventive agent for unvulcanized rubber. The agent is composed of four components: (A) a smectite, (B) a compound represented by Chemical Formula (1), (C) a surfactant, and (D) at least one substance selected from a group of inorganic silicates, carbonates, sulfates, metal oxides, metal hydroxides, red iron oxide, carbon black, graphite, and metal soaps.
Component (A) is present in the agent in a range of 20 to 80% by mass, component (B) in a range of 0.1 to 5% by mass, component (C) in a range of 5 to 20% by mass, and component (D) in a minimum amount of 0.1% by mass. These percentages are based on the total mass of the components other than water.
The patent also describes two variations of the adhesion preventive agent in the form of aqueous dispersions. The first dispersion includes the adhesion preventive agent described in claim 1, while the second dispersion includes the adhesion preventive agent described in claim 2. Both dispersions also contain water.
The patent does not provide specific details on the applications or benefits of the adhesion preventive agent. However, based on the information provided, it can be inferred that the agent is designed to prevent adhesion between unvulcanized rubber materials. The combination of components in the agent, including the smectite, compound (B), surfactant, and other selected substances, likely work together to create a barrier or surface treatment that reduces or eliminates adhesion.
The use of aqueous dispersions suggests that the adhesion preventive agent can be easily applied to rubber materials in a liquid form, potentially simplifying the manufacturing process. The specific percentages of each component in the agent and the variations in the aqueous dispersions may indicate that the effectiveness of the agent can be tailored for different applications or rubber compositions.
Overall, this patent presents a novel adhesion preventive agent for unvulcanized rubber, offering potential benefits in various industries that utilize rubber materials. Further research and development may be required to fully understand the applications and advantages of this agent.
