- Applications
- Functions
Basic Information
The ACRYSET™ BP series of products are epoxy resins with a sea-island structure before curing.
Nippon Shokubai’s proprietary acrylic rubber microparticles are evenly dispersed in bisphenol A epoxy resin and bisphenol F epoxy resin, which improves brittleness – the main defect of epoxy resin-cured products. It also eliminates variations in physical properties caused by curing conditions and reduced heat resistance, which are seen in the conventional technology of liquid rubber modified epoxy resin-cured products.
This means products cured using the ACRYSET™ BP series are highly resilient with little internal stress, and excellent adhesive force and crack resistance, making them suitable for use in various applications.

Features and Properties
- Toughness
- Heat-resistant (around 180-200℃)
- Significantly eases internal stress
- Strong adhesive force
- Excellent durability
- Excellent crack resistance
