Fibreglass & Resin Products for Mining in Namibia

Match the resin to the stream: isophthalic (NCS 991) handles dilute acids, process water and general chemical service economically; vinyl ester (Derakane 411) is the specification for hot, concentrated or oxidising streams — acid plant areas, aggressive leach circuits. The cost gap is real, so line the aggressive zones in vinyl ester and the balance in iso rather than over-speccing everything.

Routine patches are absolutely maintenance-crew work with the right kit: grind to sound laminate, acetone-wipe, laminate mat and resin in staged layers, topcoat. We supply the full basket — resin, catalyst, mat, rollers, acetone — plus application guidance. Full-tank relines and inspection-certified work stay with specialists, but the 80% of failures that are local damage should never wait for one.

Directly — at 38 °C in a summer workshop, standard catalyst ratios gel resin in the bucket. Drop toward 1% MEKP, mix small batches, shade the drums, and schedule big laminating jobs for night shift when the exotherm maths works with you instead of against you. Our counter gives seasonal starting ratios with every drum.

Epoxy tar (EPD 100) is the traditional heavy-duty answer for buried pipe, bund walls and immersed steel — thick, black, and chemically tolerant. For splash zones and repairs, epoxy systems with glass reinforcement rebuild and protect in one operation. Surface prep decides the outcome: budget the abrasive and the degreaser, not just the coating.
