Prokem PB 364 Gets First Use in Oxford

Prokem have employed a new vinylester resin in the refurbishment of a damaged nitric acid bund in Oxford UK.

Initial investigation revealed that the glass reinforced plastic (GRP) lining had delaminated on two walls and the floor of the containment bund.

A large crack had formed across the floor of the bund. When opened, the underlying concrete had perished to a depth of 150mm (6”) due to acid penetration, presenting a very real risk of leakage and pollution.

Prokem repaired the damage, removing the damaged concrete and refilling the void with a composite of sand and vinyl ester resin. Once repaired, the bund was reconditioned and relined with the new product - PB 364 – chosen for its exceptional resistance to nitric acid.

PB 364 offers resistance to Nitric acid at concentrations of up to 60%.
