How much is “enough” when it comes to adhesive?
More adhesive isn’t necessarily better when you want an effective bond or seal. Covering the bond surface is the main requirement. The type of adhesive and the bonding environment have a lot to do with how much is “enough” and how much less or extra will cause adhesive failure. Adhesive failure is a common issue […]
How To Bond Plastic To Metal
There are metal adhesives and plastic adhesives but what to do when you want to bond plastic to metal? There are metal adhesives that bond some plastics and plastic adhesives that bond some metals. The specific substrates, as well as the surface condition of the substrates, the types of stresses on the bond, and the […]
Metal Bonding Acrylic Adhesives
Metal Bonding Acrylic Adhesives Epoxies, Cyanoacrylates, and several other technologies provide excellent adhesion to metals. But, acrylic metal bonding adhesives are often a good choice not only for the strong bonds to metals but also for the variety of curing options available, which can optimize production processes. Many acrylic adhesives form strong bonds to a […]

Industrial adhesives Vs Consumer adhesives
What are industrial adhesives? How do they differ from consumer adhesives? Strictly speaking, industrial adhesives are adhesives that are labeled for industrial use. Various local and global bodies require industrial adhesives to include specific language on each label based on the chemistry. With all that is required – it doesn’t leave much room for images […]
5-minute epoxy – more than the name implies
Recently I received a call for a 5-minute epoxy. In general terms, 5-minute epoxy refers to two-component epoxy that start to set up in around 5 minutes. But they are not all alike. Epoxies can vary in viscosity, mix ratio, color, specific gravity, gap fill ability, hardness, elongation, dielectric strength, conductivity, strength, temperature resistance, and […]
Pipe Size Diameter and Pipe Sealant Use
Permabond LH050 general purpose anaerobic pipe sealant is for use on metal pipe. Permabond LH050 is classified by Underwriters Laboratories Inc.® for use in devices handling gasoline, petroleum oils, and natural gas (pressure not over 300 psig) not exceeding 2 in. pipe size; propane and butane not exceeding 1 in. pipe size. And it is […]
Choosing a High Strength Structural Adhesive
A structural adhesive is an adhesive that forms a bond which bears a structural load. Two of the most common types are epoxy adhesives and acrylic adhesives. Often both types will work for structural metal bonding application. Choosing the best type of high strength structural adhesive for the application depends on several factors. Understanding the […]
Industrial Adhesives for Dissimilar Substrates
Bonding Dissimilar Substrates It goes without saying that if you are bonding plastics use a plastic adhesive and if your bonding metal, an adhesive for metal. It gets more complicated when you want to choose industrial adhesives to join dissimilar substrates. Plastic to Metal Industrial Adhesives Two HUGE categories here – there are likely an […]
Efficient scale up – Adhesive processes
One of the questions our tech team asks engineers seeking an adhesive recommendation is “How many assemblies will you be manufacturing?” Although, from a business perspective, this is nice information to have. It is critical information to make an ideal product and process recommendation. Often, the right viscosity, rheology, and set time of a process […]
What is Permabond 2K Primer and Adhesion Promoter
Permabond 2K Primer is a multi-purpose product. It is ideal for preparing substrates for bonding, identifying if the surface is wetting out properly, or if additional surface preparation is needed. 2K Primer contains an adhesive promotor to increase bond strength. Therefore, it is ideal for preparing metal, glass, plastic, and composite for bonding. When bonding […]
