Plexus MA422 Methacrylate Adhesive
At a glance
- Methacrylate adhesive
- Working Time: 17–20 minutes
- No primer needed
Plexus MA422 is a two-component methacrylate adhesive specifically developed for structural bonding of thermoplastics, metals, and composite assemblies. The adhesive has a 10:1 mixing ratio and a working time of approximately 17 to 24 minutes. At a temperature of 23°C, Plexus MA422 reaches around 75% of its final strength within 35 to 40 minutes.
This adhesive is widely used in composite bonding applications within the transport and marine sectors, as little to no surface preparation is required. Plexus MA422 stands out due to its unique combination of excellent fatigue resistance, very high impact strength, and superior toughness, resulting in durable and reliable bonds.
Applications
Plexus MA422 is suitable for bonding the following materials:
- Aluminium
- Gelcoat
- Stainless steel
- PU
- GFRP (glass fibre-reinforced plastic)
- Polyester

Adhesive type describes the family of adhesive or sealant, such as epoxy adhesive, (methyl)methacrylate adhesive, polyurethane adhesive or polymer sealant. Its chemistry affects processing, curing, flexibility and adhesion. Products of the same type may still differ, so check the suitable substrates and application instructions.
- Methyl Methacrylaatlijm

Mixing ratio indicates how much of each component is needed, for example resin (A) and hardener (B). A ratio of 100:50 by weight means 100 grams of A to 50 grams of B; by volume you might use millilitres. Weight and volume ratios are not necessarily the same because the components may have different densities. Accurate measuring is important for proper curing.

Curing time is the period a product needs to reach a specified stage of cure. It is usually given in hours or days, often at a reference temperature such as 20 °C. A product may be tack-free or safe to handle before reaching its full mechanical and chemical resistance. Film thickness and mixed quantity may also affect the time.

Working time is the period during which a product remains workable after mixing or activation, usually given in minutes at a specified temperature, often 20 °C. With reactive resins, the chemical reaction also continues in the mixing container, and larger quantities or higher temperatures can shorten this time. Working time is different from gel time and full curing time.
- Approximately 17-24 minutes
