Manufacturing Process: Waterproof Coating on Roof (with Diagram)

- Raw Material Blending: High polymer elastomers, stabilizers, fillers, and additives are prepared (ISO 9001 verified batch control).
- Melting & Mixing: Automated reactors melt & blend raw materials at 165-200°C (Process control: PID loop).
- Extrusion & Sheet Formation: Homogenized melt is extruded into continuous roofing membranes; thickness calibrated by CNC roller press.
- Surface Treatment: Calendering and lamination; surfacing possible with anti-UV granules for enhanced weather resistance.
- Cooling & Curing: Gradual cooling to prevent thermal stress microcracks; curing under controlled humidity.
- Cutting, Inspection & Packaging: Sheets cut to size, subjected to tensile, elongation, and impermeability testing per ANSI/ASTM D1970 benchmarks.
- Site Application (View Demo Video): Membranes are torch-applied, cold-adhesive, or self-adhesive installed by certified crews.
Waterproof Coating: Main Material Types and Standard Compliance
- High Polymer Waterproof Membrane for Roof: Modified TPO, EPDM, and PVC—superior elongation, heat & chemical resistance, suitable for harsh industrial environments.
- Polyurethane Coating: One-/two-component, liquid-applied, forms seamless and highly elastic waterproofing layer.
- Bituminous Membrane: SBS/APP modifed, torch- or self-adhesive, time-tested but moderate in UV/weatherability.
All membrane types are produced and tested in accordance with ISO 9001 (Quality Management), ANSI (American National Standards), and region-specific codes such as EN 13956 (Europe). If your project specification requires compliance with LEED or ASTM D1970, high-polymer and energy-saving waterproof coatings are strongly recommended.
