AI Technical Summary

Benefits of technology

This new type of chemical called an oxirane compound that makes up most types of plastics used today are made from organic materials like phenol formaldehyde or melamine cyanate ester. These chemistries have very quick cure rates but they take longer than usual when mixed with other substances during production.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the speed and effectiveness of producing high quality electronics (electronic devices) from epoxide resins without requiring excessively longer periods for complete curing or causing damage during production processes such as bonding wires onto printed circuits board(PCB).
