Liquid silicone rubber product claimed to provide improved curing properties and safety
Tokyo – Shin-Etsu Chemical Co. Ltd has developed a new one-component Liquid Silicone Rubber (LSR) that cures at room temperature by reacting with atmospheric moisture.
Branded as KCP, LSR is claimed to offer “superior combined characteristics including heat resistance, cold resistance, weather resistance and exceptional electrical properties”.
Target applications include adhesives/sealants and coatings for products such as electric vehicle (EV) components, semiconductors and electrical/electronics.
Removing the need for heating or UV equipment means LSRs curing at room temperature will help reduce environmental impact, Shin-Etsu added.
KCP products, he explained, release cyclopentanone during the rapid cure reaction, so adhesion develops quickly, giving tack-free times about half of those seen with conventional LSRs.
“The odor generated at the time of curing is lower and has a higher level of safety,” according to Shin-Etsu.
And, he continued, “because the ignition temperature is high, over 70℃, the handling time and effort required during transportation and storage can be reduced.”
