Viscoelasticity control technology
This technology optimizes the physical characteristics forming the basis of materials according to the requirement specifications.
Viscoelastic characteristics are controlled from gel (103 Pa) to hard (109 Pa) to be compatible with shock-resistant, creep-resistant, distortion relieving, damping, scratch-proofing, and heat-resistant fixing etc.
Distortion relief, damping, and shock resistance
- Elasticity can be as low as 103 Pa by optimizing the proportion between chemical cross-linking and physical cross-linking.
- Distortion can be lowered to the utmost by designing a low-elasticity resin film.
- High vibration prevention and damping characteristics can be exerted by controlling the Q-e value.
- Shock resistance can be added by optimizing E’/E’’.
＜Case of technology application＞
● It can be seen that the glass does not scatter after dropping a ball onto a test piece bonded with the resin adopting the stress reduction technology.
(The left is a test piece consisting of two pieces of glass bonded with a frame tape, and the right is a test piece bonded with a resin adopting the stress reduction technology.)
● An egg dropped down onto resin which uses the stress reduction technology remains unbroken.
Creep and heat-resistant fixing
- Has high fixing strength even at high temperatures by increasing the cross-linking density.
- Creep resistance is increased by selecting the molecular structure and controlling the cross-linking density.

With excellent compression resistance, the original shape is restored without creep deformation even when used under high temperatures for a long time.
