Sulfurized rubber sheet waterproofing "NP Sheet No. 2 waterproofing method"

Sulfurized rubber sheet waterproofing "NP Sheet No. 2 waterproofing method"

Corresponding to the advancements and developments in modern architectural technology! Lineup includes S type and S with adhesive (made to order).

The "NP Sheet No. 2 Waterproofing Method" is a technique that combines a vulcanized rubber sheet primarily made of durable ethylene propylene diene monomer (EPDM) and a tape-like sealing material primarily made of butyl rubber (IIR), which has excellent airtightness. To enhance mechanical strength, reinforcing materials are mixed into the polymer (rubber) and vulcanized to create an elastomer that excels in weather resistance, cold resistance, and heat aging resistance, covering a wide temperature range from low to high temperatures. Additionally, it is a waterproof material that has excellent followability to cracks in the substrate and movements of the building, making it suitable for exposed waterproofing. 【S Type Features】 ■ Uniform sheet across all layers ■ Excellent weather resistance ■ Good cold and heat resistance, maintaining rubber elasticity from -40°C to 120°C ■ Good chemical resistance to acids and alkalis ■ High fatigue resistance *For more details, please refer to the PDF document or feel free to contact us.

Urethane Coating Waterproofing "Sepiron Waterproofing Method"

Urethane Coating Waterproofing "Sepiron Waterproofing Method"

The hardened coating has a stretch rate of over 650%! It can also follow the behavior of the substrate, providing reliable waterproof performance.

The "Sepiron Waterproofing Method" is a new urethane waterproofing technique developed while addressing challenges such as reducing environmental impact and achieving high durability. With consideration for the environment, the standard specifications boast rapid curing properties that allow for hardening even in winter by the next day. There are two methods: the "Sepiron Q Method," which is "not subject to special regulations," and the "Sepiron E Method," which is more environmentally friendly, uses solvent-free urethane, and all standard specifications are "not subject to special regulations or organic regulations." Additionally, we offer the composite insulation waterproofing "Sepiron M Method," which combines urethane waterproofing materials with modified asphalt sheets. 【Features】 ■ Excellent workability (rapid curing) and shortened construction period ■ Walkable ■ Seamless with a beautiful finish ■ Lightweight, putting no burden on the roof ■ Compatible with complex substrate shapes *For more details, please refer to the PDF materials or feel free to contact us.
