What are the Different Types of MSDS Adhesive?

There are nine separate categories for MSDS adhesive, with 30 total sub-categories, each of them obtaining the classification because of their chemical makeup, bonding, and setting properties. Grouping similar adhesives together on the MSDS, which stands for Material Safety Data Sheet, allows for consumers to quickly and accurately reference which of them would be the most suitable for any given project, and it also addresses safety hazards that could arise due to improper storage or inhalation.

Cyanoacrylate, also called super glue, is listed on the MSDS adhesive chart as i1-i5.

An Epoxy is a general-use MSDS adhesive that is classified between E1-E6 depending on the flexibility once completely hardened. It is formulated to be able to bond to almost any surface, and the quick-set time makes it useful for many types of projects. Epoxy is also thought to provide ample strength to create a permanent bond within most rigid materials, which is why this solvent is used within many types of industries.

Urethane is another fast-setting MSDS adhesive that can be applied to many different kinds of wood, metals, and plastics. It is commonly used when two different composites have to be permanently bonded, which many other adhesives struggle to do well. This type of adhesive is classified as either U1 or U2, based on the total setting time. IQ glue, listed simply as IQ on the MSDS adhesive list, features very similar properties and is often used as a substitute. Many businesses opt for this adhesive in all of their bonding needs because of its durability and ease of use.

Methacrylate adhesives are designed for either plastic (M1) or metal (M2) and provide resistance to both chemical and weather resistance. This type of MSDS adhesive is normally considered for industrial use because of these properties and is mainly used outdoors. It can also withstand both extremely hot and cold temperatures and contains one of the highest shear strengths within this category, making it popular within the construction industry.

There are several other MSDS adhesives that are used in specific circumstances. A cyanoacrylate instant adhesive can bond two pieces together in less than 10 seconds—on the MSDS adhesive chart, this compound is listed as i1-i5. Wood, paper, and fiber adhesives are classified G1-G4, and this category makes up the general purpose wood glues. PermaTack adhesives, denoted as P on the MSDS chart, are designed for labels and various kinds of tape. Threadlocker adhesives, which are denoted as T1-T5, are applied to threaded fasteners in order to create a semi-permanent seal.
