E-TEC’s urethane adhesive to be used in high-end sports car

Emerging Technologies

Tokyo, Japan – January 12th, 2011 – JSR Corporation (President: Mitsunobu Koshiba) is proud to announce the use of its poly-urethane adhesive "Mighty Grip" in the new Lexus LFA sports car. It will be applied on the carbon fiber reinforced plastic (CFRP) parts of the car. CFRP is a lightweight material that is nevertheless very strong and rigid. It has been used in higher end cars for quite some time but recently it is also gaining attention as a construction material for mainstream vehicles. As such it is expected that the use of this material will increase dramatically in the near future and this will lead to an increase in the demand for "Mighty Grip".

The strengths of "Mighty Grip" lie in its fatigue resistance, shock resistance and peel strength. In addition, the stress of the bonding is not located in a single point as with conventional bonding techniques (riveting, screwing, etc.) but is dispersed throughout the entire adhesive layer. The strength and elongation of "Mighty Grip" can be altered from super-soft to extremely hard and anything in between. It is a 2-component glue with a hardening rate that can be matched to the manufacturing process. All these degrees of freedom open up some interesting possibilities for the design and production process of a vehicle. In addition "Mighty Grip" does not contain any solvents, making it an environmentally friendly product that is safe to use in many production environments.

"Migthy Grip" is a product from Emulsion Technology Co. Ltd. (President: Akira Tsuji, E-TEC). E-TEC manufactures emulsion-based chemicals. It has plans to expand into the electronics devices domain, for example using "Mighty Grip" as an adhesive for the back sheets of photovoltaics. In addition, the company is also looking into the development of pressure sensitive adhesives for UV-curing. E-TEC is part of the JSR Corporation group and has its headquarters in Yokkaichi, Japan.
