Product Details
Product Overview
It is an advanced composite matrix resin widely used in the production of high-performance composites, particularly well suited for manufacturing high-temperature-resistant copper-clad laminates and high-temperature-resistant laminated boards, and can serve as a replacement for Kerimid 701A polyimide resin.
Product Chemical Description
It is a bismaleimide-based polyimide resin system that contains no DDM or similar components in its chemical composition, thereby meeting green and environmentally friendly requirements.
Product Features
- High glass transition temperature and thermal stability (the original text incorrectly reads “high glass pigmentation temperature”; this has been corrected).
- Excellent solvent resistance.
- Low coefficient of thermal expansion (CTE, T-axis).
- High copper foil peel strength.
- Good storage stability.
Product Usage
Depending on the required solid content, dilution can be carried out using organic solvents such as acetone. When preparing copper-clad laminates with pure resin, the resin should be diluted with a solvent to a solid content of 40–65% under conditions below 80°C before use. When preparing copper-clad laminates in combination with brominated epoxy resin, the amount of brominated epoxy resin added should be such that the pure resin solution does not exceed 20%, and an appropriate amount of inorganic flame retardant [Al(OH) 3 ], dilute with a solvent to a solid content of 40–65% under conditions below 80°C before use. Prepregs are prepared using reinforcing fibers (glass fiber, carbon fiber) for use in laminated products.
