The "TOYOOKI Vacuum Valve" is a high-performance vacuum valve that achieves a rapid shut-off speed of 0.007 seconds. By linking with the molten metal sensor, it reduces high vacuum and valve malfunctions. Additionally, the chuhatsu-made controller enables a reduction in cycle time. *For more details, please download the PDF or feel free to contact us.

Rayseal 100 is an impregnant that seals porous laminated products and provides pressure resistance. **Features** - It is a 100% reaction-curing (solvent-free) type. - By using an impregnation device to perform vacuum impregnation treatment, the liquid penetrates and cures throughout the interior, achieving a high sealing and sealing effect. It is particularly suitable for powder sintered laminated products.

Impregnation is a technique that fills the voids in castings and the gaps in sintered parts with resin (impregnation agent) and hardens it to seal the cavities. Super Seal P-601 combines high impregnation effectiveness with excellent durability and cleaning performance, and is used worldwide, including in Japan, as a standard organic impregnation agent. **Features** - **High Impregnation Effectiveness**: Due to its low viscosity and low surface tension, it has significantly high permeability and excellent metal adhesion, resulting in high impregnation effectiveness. - **Excellent Durability After Impregnation Curing**: It possesses excellent heat resistance and chemical resistance, making it suitable for impregnation in various applications. - **Sufficient Cleaning Effect with Just Water Washing**: Being water-soluble, it has excellent cleanability and provides high cleaning effectiveness for various shaped parts. *For more details, please contact us through the download.*

Anaerobic spot sealing agent Altach 1180 has high permeability for metal defect holes and hardens upon contact with metal to seal the area. It is easy to handle and economical as it allows for treatment of only the necessary areas. **Features** - **No hassle**: It is a one-component, solvent-free spot sealing agent that is easy to handle. Additionally, it has the ability to harden when air (oxygen) is blocked, eliminating the need for heating or equipment. - **Versatile**: With low viscosity and excellent permeability, it is suitable for filling seals in welds and pinholes in castings. - **Outstanding hardening**: With 100% active ingredients, there is no shrinkage in the filled seal area, resulting in an increased sealing rate. - **Shortened processing time**: When used with a hardening accelerator, it hardens in a short time, contributing to time savings.
