 Drop impact resistance type

What is the PLENSETTM Drop impact resistance type?

Generally, epoxy resins are hard and brittle, but with our proprietary compounding technology, we have succeeded in creating a flexible composition. This results in improved impact resistance, stress alleviation, and stronger, more flexible joints.

Have you experienced these issues?

The adhesive area is so small that the adhesive part peels off or breaks during drop impact testing, etc.

Here is the product that resolves these issues.
PLENSETTM Drop impact resistance type

It can be cured at a low temperature of 80degC, unparalleled for a one-component epoxy resin.
Feature
#1
icon
Once cured, it gains a rubber-like elasticity, providing flexibility that is effective for stress alleviation as well as shock and vibration absorption.
Feature
#2
icon
Due to its low elasticity, it has high peel strength and is effective for bonding dissimilar materials with large differences in linear expansion coefficients.

Application

Adhesion to parts subject to shock and vibration
Adhesion to dissimilar materials and those that are difficult to bond (engineering plastics such as LCP and PA9T, metals such as gold and nickel)
Adhesion and bonding to flexible substrates, displays, and other components that require flexibility
Adhesion and encapsulation of thin-film components without warping or deformation

Warpage in molding wafers

Wafer: 12 inches, 0.8 mm thick Mold: 0.4 mm thick
Warpage does not occur with the drop impact resistance type even when molding on one side of the wafer.
