Urethane adhesive MIGHTYGRIP™ 【MIGHTY series】

Over 30 years of experience with urethane adhesives

Product outline

The micro phase separation structure of urethane resin realizes “flexible adhesion” that combines toughness and flexibility.
We have more than 30 years of experience with adhesives for various uses such as automotive panels which requires high reliability.
Using the primer dedicated for the respective material improves the adhesion strength to various materials.

Property

Flexible adhesion

By controlling the micro phase separation structure, which is a characteristic of urethane resin, “flexible adhesion” that combines toughness and flexibility is achieved. It improves “fatigue resistance”, “impact resistance” and “peeling resistance” of the bonded structure.
Over 30 years experience

We have more than 30 years of experience with adhesives for various uses such as automotive outer panels that requires high adhesion reliability. The recognition of this achievement has developed and expanded a wide range of applications including housing equipment, building materials, and ships.
Mixing method

MIGHTY GRIP® is used by mixing two-component adhesives. Above video introduces the Bag-mixing method for small scale. We can offer cartridges, dispensers, etc. depends on your scale of use.
Synergistic effect with dedicated primer

Using the dedicated primer improves the adhesion strength to various materials.
This synergistic effect combines the strength of urethane adhesives with high adhesiveness and achieves the bonding between dissimilar materials such as Aluminum and CFRP.
Total technical support for adhesion

While meeting the needs of customers in a wide range of adhesive fields, we have accumulated know-hows and technical knowledges of the urethane bonding process over the past 30 years in our history.
With the know-hows and knowledges, we can provide technical suggestion about the selection of adhesives, mass-production processes, and whatever you need.
