Basekim’s Oxidized Bitumen 105/15 is a hard, semi-solid bitumen specially air‑blown to raise its softening point (~100–110 °C) and reduce penetration (~10–20 dmm), resulting in superior thermal stability, water resistance, and durability—ideal for waterproofing, roofing, road joint sealing, tank linings, and pipeline coatings. Available in bags, drums, or bulk, it adheres well to diverse substrates and complies with international standards, offering reliable long‑term performance.
