We design “adhesion technologies” for our customers.
Our original brand “WORLD ROCK”
The technologies behind our corporate history and proprietary product portfolio were developed
to share the issues you are facing and realize your dreams.
With our corporate philosophy, “Designing adhesion technologies from our customer's perspectives,” our development strategies are promoted by integrally building on three systems: “additional function design,” “assessment technologies”, and “process proposals” based on our adhesion technologies.
Designed “adhesion” products
Before LCD monitors became the mainstream instead of CRT-based televisions, products used to be manufactured by using the “injection method” in spite of a number of problems. To cope with such problems, Kyoritsu Chemical & Co., Ltd. succeeded in developing and commercializing a new adhesion technology called the “One Drop Filling (ODF) method,” which allows the outer sealing material and liquid crystal to be bonded together completely at one time without causing any chemical reaction or contamination.
“Adhesion” technologies used
for smartphones
As capacitive touch panels are being adopted for smartphones in recent days, market needs for transparent and flexible (low-elasticity) optical adhesives called Optical Clear Resin (OCR) are rapidly growing. Since the 1990s, we at Kyoritsu Chemical & Co., Ltd. have been responding to technical issues surrounding devices equipped with touch panels, reflection-averse aeronautical instruments, etc., to eventually develop OCR products under the “WORLD ROCK” brand, which are currently adopted in a number of smartphones.
