Key factors to consider when using a PU adhesive
Due to their excellent bonding strength, flexibility, and durability, polyurethane adhesives are a popular choice in a wide variety of industries. These adhesives are versatile and can bond an extensive range of materials, including wood, metal, plastic, honeycomb, and insulation materials.
When using a polyurethane adhesive, there are several key factors to keep in mind to ensure a successful bond and these include:
- Surface Preparation: Crucial to ensure a strong and lasting bond
- Adhesive Application: Choosing the correct method plays a pivotal role in achieving the desired results
- Open and Cure Times: Essential to ensure efficient production processes
- Bond Strength: Crucial for the durability and longevity of the final product
Surface Preparation
Prior to applying polyurethane (PU) adhesive, it is important to correctly prepare the surfaces to be bonded, to ensure a strong and durable bond.
Remove any dust, dirt, grease, or contaminants from the bonding surfaces using a suitable cleaner such as isopropanol.
Our two-component primer has been designed as a pre-treatment for non-ferrous metals such as aluminium, copper, brass, zinc and nickel and is ideal for use in panel lamination.
Adhesive Application
Polyurethane adhesives can be applied either manually or automatically by rolling or beading, complementing a variety of manufacturing methods from a simple hand applied system to the
most advanced automated machinery.
We work with a number of leading adhesive application equipment manufacturers to offer a complete package and our experienced engineers are also available to offer support and assist with any maintenance or servicing requirements you may have.
Open and Cure Times
We can offer a variety of adhesive formulations with different open and cure times to suit your specific manufacturing process.
Open Time: Refers to the duration during which an adhesive remains in a workable or liquid state after application, before it begins to set or cure.
Cure Time: Refers to the period required for an adhesive to fully set and achieve its intended physical and chemical properties, such as strength, hardness, and durability.
Bond Strength
Polyurethane adhesives have been a popular choice in many industries due to their excellent bond strength and versatility.
They can form a strong and durable bond between a wide range of materials including metals, plastics, wood, honeycomb and insulation.
They also offer good resistance to chemicals, moisture, and UV exposure, making them the ideal choice for more challenging environments.
