Methyl Methacrylate Adhesives

Methyl methacrylate (MMA) adhesives have a different cure mechanism than other two component reactive adhesives. These adhesives, based on a modified type of acrylic, are fast curing and offer high strength and toughness.

Supplied as two parts (resin and catalyst), they are usually mixed immediately before application. Some more specialised types are also available where the components can be applied in separate operations: the resin component to one surface to be bonded, the catalyst to the other. They tolerate minimal surface preparation and bond well to a wide range of materials like metals, engineering plastics, composite and fiberglass. The products are available in a wide range of cure speeds and as liquids or pastes.

The cure profile of MMA adhesives can be adjusted more readily than other types of two component adhesives. This allows formulation of adhesives that have a slower reaction rate immediately after mixing to allow more time for adhesive application and assembly of parts (longer worklife). After a short period of time (induction period), the rate of reaction increases to provide more rapid strength build-up. This reduces the time components need to be fixtured before bonded assemblies can be processed further.

Acrylic Adhesives No-Mix Structural Adhesive System

Acrylic Adhesives are well-known for their durability and strength and usually made from esters of acrylic, methacrylic and cyanoacrylic acids. Acrylic adhesives are used for applications that require high tensile and shear strength with shock and stress resistance.

Some of the main advantages of Acrylic Adhesives are listed below:

Quick settling time; almost twice as fast than ordinary Acrylic adhesives
Low Odor and hence better working environment
High tensile strength even on difficult to bond substrates
Optically clear
Electrically insulated

PARTITE Acrylic Adhesives are no mix, two-part system. Simply apply Acrylic Adhesives to one surface, the activator to the other and join parts together. Fixture time will range from 60 seconds to 5 minutes depending upon the grade.

Following are the most popular grades with specifications. Custom formulations and variety of packing are available.
