Product Description
BMI-3000-C GEL - Catalyzed is a pre-catalyzed bismaleimide oligomer that exhibits excellent flexibility and, on cure, forms very tough, hydrophobic polyimides. The material has excellent hydrolytic stability and thermal stability. As an additive it can improve rheological properties by increasing the thixotropic properties of a liquid monomer composition. This feature in turn can help to reduce resin bleed out on a variety of surfaces.
BMI-3000-C Precatalyzed Gel is soluble in most aromatic solvents such as toluene, xylene, tetralin, etc. It is also compatible with and can be incorporated directly into many resin systems for enhanced performance.
BMI-3000 GEL - Catalyzed is recommended for use as an additive to increase flexibility, hydrophobicity and thixotropy. It has excellent adhesion to a variety of substrates. The pre-added catalyst allows used directly in thermal cure applications without the need for an additional formulation step. The material forms excellent films that can subsequently cure thermally. When used as a base resin, it can produce films that are tough, flexible and demonstrate good peel strength.
BMI-3000 GEL - Catalyzed is designed for thermal curing. A minimum of one hour at 150°C is a recommended starting point. Higher temperatures (up to 175 – 180°C) will result in significantly shorter cure time requirements. Curing below 150°C is not recommended. Due to its solvent free nature the curing of BMI-3000 GEL - Catalyzed is generally independent of ramp rate – both hot plate or oven are acceptable curing devices.
