METHACRYLATE ADHESIVES

Methacrylate Adhesives

Methacrylate Adhesives (MMA) are uniquely different from 2 component epoxy system as their formulation is based on modified acrylic monomer that will yield high bonding strength and toughness in a quick setting time. Methacrylate Adhesive from Araldite, Everwide and Partite are preferred structural adhesives by the R&D and manufacturing engineers as it can set and cure rapidly with adhesion strength comparable to epoxy.

Most Methacrylate Adhesives aresupplied in the format of a Resin and Catalyst and when mixed in the right ratio or proportion,  it will give rise to fast reactivity (between 5 - 20 minutes) with some heat being released in the process and resulting in extremely high bonding strength to the bonding materials. Apart from its tough and robust bonding strength, it can withstand extreme outdoor weathering and variable temperature cycles without losing its adhesion strength. For specific requirements, this methacrylate adhesive can also be supplied in no mix system whereby, the Resin and Catalyst are applied separately on the substrates before placing them together for bonding. 

Methacrylate Adhesives are so versatile that minimal surf ace preparation is required to achieve optimal bonding strength and its ability to bond strongly to most metals, engineering plastics like ABS, PC, PET, composite, fiberglass, wood, and some rubbers.

No Mix Methacrylate Adhesive Grade

Agomet No Mix Methacrylate Adhesives are solvent-free reactive acrylic systems, i.e. the strength of the adhesive (cohesion) itself is built through a chemical reaction. In 2-component types, this process is started by mixing the components thoroughly. The mixture's low initial viscosity ensures thorough spreading over the surface, an important pre-condition for final adhesion. As the reaction progresses, the viscosity increases until the adhesive are no longer free-flowing. Once the working time of the mixture is exceeded, it can no longer be applied properly, yet the chemical reaction continues. The final strength of the the bonded joint is reached after a number of hours or days, depending on the adhesive used, whereas the assembled parts can be handled earlier

A new line of surface-activated methacrylate adhesives, designed to increase customer bonding options, has been introduced by Huntsman Advanced Materials. The Adhesives allow fast cure and durable joining of metals, thermoplastics and composites. The high strength adhesives are suitable for use in the loudspeaker, electrical/electronics,
transportation, marine, construction, furniture and general fabricating industries.

Known as Agomet® methacrylates, the eight adhesives and four hardeners are part of the broad Huntsman Advanced Materials range of Araldite® structural adhesives. The new products exhibit the unique ability to bond substrates via surface pre-activation or by bead on bead application. Surface pre-activation allows users to apply hardener/lacquer to a substrate up to 30 days before the adhesive is added to bond an assembly. The adhesives can also be hand mixed or can be dispensed by meter-mix machines.

Easy-to-apply Agomet methacrylates are ideal for bonding small and large areas; with work lives ranging from one to twenty minutes. Handling time varies from two to thirty-five minutes, and the adhesives have gap-filling properties from 0.4 mm to 5 mm depending on the application method used. Cured Agomet methacrylates exhibit lap shear strengths as high as 35N²/mm.
