Components that bear heavy loads require a variety of properties in their surfaces, including resistance to rust and corrosion, durability and a thin profile. TAKECOAT® 1000 is a thin, durable film that is resistant to rust and corrosion. Enabling a high level of lubrication on the surface, TAKECOAT® 1000 is created by combining special treatment technology with a two-layer construction, developed through research, that is composed of a fluorocarbon polymer film and a special under treatment film.

Properties 1: Resistance to Rust and Corrosion Prevention

The two-layer construction of TAKECOAT® 1000 provides anti-rust protection recognized as superior in outdoor exposure tests and actual use in environments including ocean surface and undersea applications. Such third party agencies as the Japan Quality Assurance Organization and KTA in the US have verified the superior properties of TAKECOAT® 1000 in indoor accelerated corrosion tests. The photo below shows the results of a salt spray test conducted by KTA.

Properties 2: Durability for Secure Fastening

Due to the high lubrication and hardness of the fluorocarbon polymer film, even if a heavy load or shearing force of tens of tons is applied to the film surface, the film remains essentially free of damage and separation. Additionally, rusting even in damaged areas is extremely limited. This is effective for fastening bolts and other fasteners.

Properties 3: Heat Resistance

TAKECOAT® 1000 has superior heat and cold resistance due to the properties of its fluorocarbon polymer.

- Continuous use temperature range: -196°C to +200°C
- Intermittent use temperature range: -196°C to +230°C

For industrial plants with particularly high temperatures (exceeding 450°C), we recommend TAKECOAT® CERAMIC1.

Properties 4: Insulation

Fluorocarbon Polymer becomes a film that is extremely hard and thin with essentially no pinholes. Because of this, fluorocarbon polymer effectively prevents glavanic corrosion, corrosion at contact points between different metals, pitching corrosion and other types of corrosion. When using TAKECOAT® treatment for steel bolts with stainless steel flanges, a flat washer treated with TAKECOAT® 1000 should always be used.
For insulation in high-voltage environments, we recommend Elecut.

When using a part treated with TAKECOAT® 1000 for fastening, it happens on rare occasions that the film surface becomes damaged. Takenaka carries repair fluid to touch up such damaged areas, as well as special wrenches designed to prevent such film damage. Click here for more information on Takenaka’s wrenches.
