Bionil PF Pre-Cleaning
Weld and Surface Pre-Cleaning Liquid
Pre-cleaning liquid that removes fabrication contamination, oil, grease and light pitting from stainless steel and other non-ferrous metal surfaces.
High Viscosity for Vertical Surfaces

High Viscosity for Vertical Surfaces
Its high, non-run viscosity clings to vertical surfaces, allowing it to penetrate surface soils better and deliver better cleaning. Does not damage painted surfaces such as epoxy, acrylic, etc.

Bionil SV has a viscosity of approximately 4000-6000 cP. Unlike water-like 1 cP cleaners, this value allows it to cling and stay suspended on vertical surfaces independently of gravity. High viscosity means a longer contact time with the soil.
Yes, the formula is designed within a neutral to mildly alkaline pH range and is not aggressive towards the chemical structure of industrial paints such as epoxy, acrylic and polyurethane. Tank outer walls and painted machine surfaces show no darkening or blistering even after long dwell times.
