Solution Summary

  • ACRYSET™ BP disperses acrylic rubber particles uniformly in epoxy resin, improving the brittleness that is the biggest drawback of epoxy resin.

  • ACRYSET™ BP is a toughening agent that exhibits toughness even at high temperatures (100-120°C).

  • Masterbatch makes it easy to achieve uniform dispersion of rubber particles in resin, improving productivity and stabilizing quality.

Toughening agent"ACRYSET BP" achieves toughness in epoxy adhesives!

One of the members who was gathering information at an online exhibition saw an exhibition panel for Nippon Shokubai 's toughening agent ACRYSET BP series (hereinafter referred to ACRYSET BP), became interested, and immediately contacted Nippon Shokubai.

ACRYSET BP is an epoxy resin in which acrylic rubber particles are uniformly dispersed, which is said to have the effect of improving the brittleness that is the biggest drawback of epoxy resin.In addition, compared to liquid rubber-modified epoxy resins, it also eliminates the decrease in heat resistance and the variation in physical properties due to curing conditions.

The R&D department was provided with a sample of ACRYSET BP and tested its performance as an adhesive. They found that it achieved the target adhesive strength, and while other resins containing rubber components sacrifice heat resistance, ACRYSET BP was expected to maintain its toughness even at high temperatures (100-120°C).

"By using ACRYSET BP as a masterbatch, we were able to easily achieve uniform dispersion of rubber particles. This also eliminated variations in adhesive strength, and we were convinced that we could achieve both improved productivity and stable quality." (Mr. T)

Mr. T then asked adhesive manufacturers to conduct further research and detailed testing on adhesives that use ACRYSET BP as a toughening agent. Currently, discussions are underway with three companies regarding the adoption of ACRYSET BP.
