Bonding Polycarbonate with Industrial Adhesive

How to Prepare and Bond Polycarbonate Manufacturers using polycarbonate substrate materials often look to an adhesive for bonding or joining parts. Industrial adhesives offer a low-cost and convenient method of adhering parts, allowing flexibility of choice of substrate e.g. you can bond polycarbonate to other plastics, wood or metal where other bonding techniques such as...

Bonding Acrylic with Industrial Adhesive

Acrylic or PMMA (poly methyl methacrylate) is a popular thermoplastic (most commonly referred to PlexiglasTM). It is often clear / transparent and is used for a wide variety of common everyday items such as display racks, menu stands, windows and skylights, signs, displays etc. It is a lightweight and easy to handle alternative to glass. Acrylic is a great substrate fo...

Bonding Nylon/Polyamide with Industrial Adhesive

Polyamide (commonly called Nylon which is a DuPont tradename), is a thermoplastic material widely used in a number of applications across various industries.  Special blends are often available with features such as high lubricity, flexibility, and flame retardant properties.  Often, Nylon is glass-filled to give extra strength and stiffness properties.  It often has a...

Surface Energy & Wetability

Surface Energy A “wetable” surface is one which is said to have “high surface energy,” liquid can be spread across the surface without the bunching of droplets. Low surface energy materials which do not “wet out” leave liquid droplets standing proud - imagine a freshly waxed car sprayed with water droplets - the drops bunch up at a steep angle to the paintwor...

Should the nuts and bolts be cleaned before using threadlocker MM115?

Permabond MM115 tolerates some oil on the nuts and bolts.  In most cases Permabond MM115 can be used on ‘as received’ nuts and bolts, but we recommend testing to be sure - particularly if nuts and bolts appear to be heavily contaminated. A couple of points to consider: Metal ions are needed for the MM115 threadlocker to cure, too much contamination on the com...

The Importance of Surface Preparation

Why is surface preparation important in adhesive bonding? As any professional who works with adhesives knows, surface preparation is one of the most vital elements in achieving a high bond strength and optimising durability and lifespan of bonded joints. Different substrate materials will require different types of adhesives for bonding and different methods of surface pr...
