Below are performance RESINS and Potting Compounds for Surface Mounted Technology (SMT) that meet our customer requirements, or we will develop systems for you that will.

 

Would your components benefit from either EPOXY or URETHANE potting of stress sensitive electronics?  The best solution for Surface Mount Components, Boards and soldered connections are low Tg (Glass Transition) urethanes. Many of our systems have a glass transition as low as -73C, with operating temperature up to 150C.

 

efi-Polymers provides electronic Printed Circuit Board (PCB) potting system solutions to issues like:

UL94V-0 (Flame Retardant) requirements, environmental challenges, thermal conductivity barriers, low coefficient of thermal expansion (CTE), convenient mix ratios, wash down and tamper proof requirements.

UL Online Certifications: QMFZ2.E211862, OBJS2.E210549
