Flexible Bonding

What is Flexible Bonding? 

Flexible bonding is the use of flexible adhesives and flexible silicone sealants which can accommodate movement, such as thermal expansion and contraction, of the substrates they're applied to. Using flexible materials provides a durable, resilient bond which prevents cracking and breakage of the adhesive joint while also preventing the passage of gases and liquids. 

Typically, flexible bonding is used in automotive and construction industries where vibration, thermal expansion and contraction, and high stress are common. 

Types of Flexible Bonding Materials: 

Elastomeric Silicone Sealants

Elastomeric sealants are often used for joints and surfaces which are prone to expansion and contaction, hwlping to prevent leaks and water ingress. They are durable, adhering to a range of substrates and offer weather resistance. 

Elastomeric Adhesives 

Used in applications where shock, impact, and vibration resistance are required, elastomeric adhesives offer excellent thermal resistance. They are used broadly across a range of industries beacuse of their durability and elogation properties. 

MS Polymer Adhesives

These excel wherever elastic bonding is required. Solvent free, they offer low shrinkage, high adhesion, and impact resistance, as well as UV resistance. 

Cyanoacrylate Adhesives

Flexible cyanacrylate adhesives offer near instant bonding while retaining flexibility. They allow for fast bonding of substrates such as metal, plastic, and rubber, and for smaller components to be sealed instantly when working with electronics.

Advantages of Flexible Bonding: 

• Resistance to stress, mechanical shock, and vibration
• Thermal, UV, and weather resistance
• Make joints and substrates watertight, airtight, and impermeable
• High strength
• Suitable for a wide range of substrate materials
