The SIGMACOVER 300 LT is a thick‑film, two‑component tar epoxy coating for underwater ship hulls, usable down to -10 °C.
SIGMACOVER 300 LT is a thick‑film, two‑component polyamine‑based tar epoxy coating offering excellent seawater resistance, corrosion resistance, and chemical‑pollution resistance. It can be applied and cured at low temperatures as low as -10 °C and works well on both protected and unprotected underwater steel surfaces.
The product data includes density, solid content, VOC limits, recommended dry‑film thickness (125‑250 µm), theoretical coating rates, mixing ratios, diluent recommendations, safety precautions, recoat intervals, and curing times. Storage life is at least 12 months in a cool, dry place, and full cure at -10 °C takes about 7 days. This manual is written in Chinese.
