Maven MMA 4000 Acrylic - Crystal Clear Medium Set 18-Min MMA Adhesive-Low Viscosity & UV Stable Resistant-10:1 ratio

Product Name

Maven MMA 4000 Acrylic - Crystal Clear Medium Set 18-Min MMA Adhesive-Low Viscosity & UV Stable Resistant-10:1 ratio

Brief Description

Maven MMA 4000 is a two-part, 10:1 ratio methacrylate (MMA) structural adhesive known for its crystal clear appearance, low viscosity, and medium set time of 18 minutes. It is engineered to create strong, durable, and flexible bonds across a wide range of materials, including various plastics, composites, and metals. This adhesive is particularly valued for its UV stability, non-yellowing properties, and high resistance to environmental factors such as water, impact, wear, scuffing, and high temperatures. It requires minimal surface preparation and cures rapidly at room temperature, making it suitable for fast-paced production and demanding applications.

Comparison Note

Maven MMA 4000, as an MMA adhesive, offers a unique balance of properties compared to other structural adhesive chemistries like epoxies and polyurethanes. It provides a combination of high strength and flexibility, making it ideal for applications involving dynamic stresses, vibration, and impact, where epoxies might be too rigid and brittle. Unlike many epoxies, MMA adhesives generally require minimal to no surface preparation, tolerating slightly oily or unclean surfaces, which significantly reduces preparation time and cost. While epoxies often boast superior chemical and heat resistance, MMA adhesives offer faster cure times for a given work life, making them highly efficient for production lines. Compared to polyurethanes, MMAs typically exhibit higher bond strength and better resistance to impact and fatigue, without containing isocyanates, which can be a health and safety concern. The crystal clear, low viscosity, and UV stable nature of Maven MMA 4000 also provides aesthetic advantages over many other adhesive types, especially in visible bond line applications.
