New flexible sealant offers high curing speed and low-VOC application

Henkel introduces Loctite MS 9650, a next-generation adhesive and sealant engineered to exceed automotive customers’ high expectations for flexibility and sustainability.

Based on a silane-modified polymer, it cures through reaction with moisture, forming a soft elastic product that is strong enough for elastic bonding. It can bond a wide variety of substrates – including glass, metal, painted surfaces and plastics – with good UV resistance. The material shows creep behavior to the same level as a silicone-based adhesive, superior compared to other silane-modified polymer grades.

By increasing temperature and humidity, curing time can be drastically reduced. This enables applications where one-component adhesives were previously considered unsuitable due to long processing times. Curing speed varies with factors such as moisture, temperature, and joint depth. The material can be boosted using Teroson MS 9371B to speed up production with dynamic mixing. 

A new solution for automotive display components 

Loctite MS 9650 delivers strong, durable bonds with excellent vibration resistance, creep behavior and UV resilience – making it well suited to automotive display components alongside a wide range of industrial applications. 

“At Henkel, we’re committed to delivering premium adhesive and sealant solutions designed to meet the rapidly evolving demands of the automotive sector,” said Bart Van Eeghem, Business Development Manager Automotive Electronics at Henkel. “Loctite MS 9650 excels in automotive environments, so customers can expect long-term performance with minimal need for maintenance or replacement.”

An all-round approach to sustainability

Loctite MS 9650’s silicone-free formula supports low-VOC production for improved operator safety, while its zero content of isocyanates and PVC helps minimize environmental impact and waste. Additionally, it is suitable for lightweight vehicle assemblies, contributing to energy-efficient vehicles overall.

“Sustainability today means looking at the whole picture,” said Bart Van Eeghem. “Loctite MS 9650 supports a holistic approach to sustainability.”
