April 25, 2024 (press release) –
In May 2024, Kao Corporation will launch LUNAFLOW RA, a mold release agent for use in smoothly removing rubber and resin products from molds during manufacture. LUNAFLOW RA is made using cellulose nanofibers (CNF), a cutting-edge biomass material, and features superior demolding performance and durability for repeated use once applied. The product can be expected to improve work efficiency in the manufacturing process, and is both solvent- and fluorine-free, making it friendly to both the workers and the environment.

Product overview
In forming rubber or resin products in a mold, poured material adhering to the mold can lead to reduced work efficiency and give rise to defective products. A mold release agent is applied to the inside of the mold to form a thin film between the mold and the material, acting to prevent adhesion between the two. Demand has increased as products have gotten smaller and more complex, and there is a need for a mold release agent that is highly functional and requires less frequent reapplication.
Utilizing CNF, a cutting-edge material controlled for advanced oil retention with Kao’s proprietary technology, LUNAFLOW RA offers outstanding mold release properties and durability. Designed as a solvent- and fluorine-free product, it is friendly to both the workers and the environment.

Summary
In response to the needs of industries dealing with demolding issues, Kao proposes products that can help solve those issues, while aiming to develop products that can be applied to a wide range of materials beyond rubber and resin. Going forward, Kao also plans to adapt this “biomimetic slippery technology” utilizing CNF for other uses, including possibly in developing products that are more stain resistant.
