Hydrogen Fluoride Solutions for Electronics 

SAFETY INFORMATION:  Hydrogen fluoride is extremely dangerous and should only be handled by highly-trained personnel.  Failure to follow this could result in injury or death.  For  solutions of >30% HF double nitrile gloves are recommended and the use of C-alloy layered gloves or HF resistant gloves is needed. For 4 hours or more of HF exposure: Butyl rubber, neoprene rubber, Viton®/butyl rubber, Barrier® (PE/PA/PE), Silver Shield/4H® (PE/EVAL/PE), Trellchem® HPS, Trellchem® VPS, Tychem® SL (Saranex®), Tychem® CPF3, Tychem® BR/LV, 4 Tychem® Responder®, Tychem® TK.

The following gloves will protect against hydrofluoric acid (>70%) for 4 hours or more: Neoprene rubber, Barrier® (PE/PA/PE), Trellchem® HPS, Tychem® TK
