Since launching liquid gaskets in 1955, ThreeBond has been marketing various sealing materials and adhesives throughout the world based on its unique technologies and know-how.
In recent years, it has focused on the development of sealing agents for automobile electric components and developed CIPG (Cured-in-Place Gasket) materials which can show a stable sealing performance in a short time.
These materials can be applied to any kind of work by using a dispenser in place of conventional solid packing. They are also repairable, so the process control can be improved.
ThreeBond 3081J, a UV-CIPG material developed based on our most advanced technologies, is introduced below.
Gaskets are used for various purposes in the automobile and electrical and electronics markets to seal equipment from various fluids and particles, such as lubrication oil, hydraulic oil, water, and dust.
Gaskets can be roughly classified into solid gaskets and liquid gaskets according to their features.
Solid gaskets, such as O-rings and packing, have been widely used, but we are developing and marketing FIPG (Formed-in-Place Gasket) materials as alternatives to the conventional ones.

It is said that more than 100 ECUs (electronic control units) are mounted on one car depending on the model.
General solid gaskets have different shapes for the ECUs to be mounted on. First, the dies for them must be produced.
The greatest advantage of the FIPG method is that dies are not required and a gasket suitable to any kind of work can be formed simply by changing the application pattern of the application equipment. (Table 1)
Gaskets for ECU are required to have high quality reliability under severe working environments (heat resistance, moisture resistance and cold resistance). Our gaskets satisfy such high standards for reliability and greatly reduce the line tact time.
We have launched a new UV-CIPG material for ECU, ThreeBond 3081J (Fig. 2).
ThreeBond 3081J has rubber-like properties and excellent durability against permanent compression deformation under severe temperature environments from -40°C to 120°C. It also has properties necessary for ECU gaskets.
It is repairable, it can be removed more easily compared to the conventional FIPG method, and its parts can be replaced.
