"Narujasuto P" is a water-based polyethylene primer for substrate preparation. It is made from a polyethylene emulsion and aggregates, and does not use cement, which means it does not generate dust. Additionally, it has waterproofing properties, which shortens the curing time after rainfall and can reduce construction time. The formed adjustment layer has the ability to relieve vapor pressure generated from the substrate. 【Features】 ■ No need for weighing, mixing, or stirring, and no issues arise from these processes ■ No dust generation since it does not use cement ■ Does not fall under the specific chemical substance hazard prevention regulations ■ Exhibits good adhesion even in slightly damp conditions when applied to concrete substrates ■ Has waterproofing properties, which shortens the curing time after rainfall and reduces construction time ■ The formed adjustment layer has the ability to relieve vapor pressure generated from the substrate *For more details, please refer to the PDF document or feel free to contact us.

"Nalfalt Top Hard" is a high-durability finishing paint for exposed waterproofing layers, featuring a special polyethylene-based emulsion type coating with excellent water resistance, weather resistance, and adhesion. We offer two types: "High Durability P" with a viscosity of 20,000 cps and "High Durability S" with a viscosity of 25,000 cps. 【Features】 ■ Main ingredients: Polyethylene acrylic emulsion, aggregate ■ Viscosity: (P) 20,000 cps (S) 25,000 cps ■ Solid content: (P) 65% (S) 67% ■ Specific gravity: (P) 1.5 (S) 1.2 ■ Appearance: Gray water-based emulsion ■ Packaging: 20 kg poly pail *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the coating waterproofing exposed method "Nalfalt WP-S." It does not use any substances prioritized by the Healthy Housing Research Association, such as formaldehyde, toluene, or xylene, nor any substances established by the Ministry of Health, Labour and Welfare guidelines. As it is a one-component water-based emulsion, there is no need to mix two components, eliminating issues related to improper mixing. Furthermore, it can be easily applied using a roller, brush, or spraying machine. 【Features】 ■ Safe and pollution-free work as it does not use any flammable materials or organic solvents ■ No need to mix two components due to its one-component water-based emulsion ■ Exhibits strong adhesion to steel plates ■ Can be used as a substitute for anti-corrosion paint ■ Blocks solar radiation affecting the roof, mitigating temperature rise inside the building (in heat-insulating specifications) *For more details, please refer to the PDF document or feel free to contact us.

"Nalfalt WP" is a water-based emulsion type waterproofing agent made by modifying asphalt with rubber. By simply applying it in its concentrated form, a waterproof membrane is formed through natural drying. Once the waterproof membrane is formed, it will not dissolve again. It adheres strongly to the substrate and forms a tough and durable elastic membrane, making it a product with excellent workability and safety. 【Features】 ■ Non-toxic and non-flammable, safe to use ■ One-component water-based emulsion ■ High waterproofing and strong adhesion ■ Can be applied even on damp substrates ■ Excellent flexibility *For more details, please refer to the PDF document or feel free to contact us.

"Narucourt CP" is a special polyethylene-based emulsion developed by Naruse Chemical using new technology. It is a water-based type that possesses excellent corrosion resistance, has outstanding elongation properties, and offers waterproof performance. It does not contain organic solvents and does not use any raw materials that fall under environmental hormone substances such as bisphenols. 【Features】 ■ Water-based type that does not contain volatile organic compounds (VOCs) ■ Equipped with excellent corrosion resistance that sufficiently meets corrosion technology standards ■ Can be applied even if the underlying concrete is wet ■ Due to its drying and curing type, it can be applied without worrying about usable time ■ Environmentally friendly *For more details, please refer to the PDF materials or feel free to contact us.

"Narcisheet N Composite Waterproofing" is a composite waterproofing system that maximally utilizes the advantages of modified asphalt sheets (Narcisheet N) and modified asphalt emulsions (Narfalt WP). It is a method that does not use open flames, eliminating the risks of fire and poisoning, allowing for safe construction even in enclosed environments such as indoors. Furthermore, it has excellent adhesion to most substrates (mortar, concrete, metal sheets, asphalt, urethane, rubber, etc.), making it easy to apply in complex areas, vertical surfaces, and at the edges of the waterproofing layer. 【Features】 ■ Completely safe as it does not use organic solvents or open flames ■ High waterproofing performance and strong adhesion ■ Can be applied even on damp substrates ■ The waterproofing layer is flexible and elastic, providing excellent adaptability to substrate expansion and contraction *For more details, please refer to the PDF materials or feel free to contact us.

"Narucourt JW" is a polyethylene-based emulsion developed by Naruse Chemical using new technology. Despite being water-based, it possesses excellent corrosion and waterproofing properties. It is solvent-free and does not use any raw materials that correspond to environmental hormone substances such as bisphenol A, making it a product considerate of environmental measures and the workers involved. 【Features】 ■ Water-based type that does not contain volatile organic compounds (VOCs) ■ Equipped with excellent corrosion resistance that sufficiently meets the guidelines for corrosion protection technology ■ Can be applied even when the substrate concrete is damp ■ Viscosity that allows for smooth work ■ Environmentally friendly *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Narcise N Composite Method." The "Narcise N" used in this method complies with the modified asphalt roofing standard JIS A 6013. "Narcifalt WP" is a water-based single-component product that does not use organic solvents, and since the film dries and hardens, it does not contain any substances of health concern. In the case of renovation work for rooftop waterproofing where the existing waterproofing has an exposed asphalt finish, the compatibility of similar materials, along with the reliability of asphalt waterproofing, is highly regarded. 【Features】 ■ Combines toughness and water tightness ■ Covers the weaknesses of modified asphalt adhesive sheets ■ Simplifies the structure of upstands ■ Can be adapted to the specifications of the Ministry of Land, Infrastructure, Transport and Tourism ■ Complies with JIS A 6013 modified asphalt roofing standard *For more details, please refer to the PDF document or feel free to contact us.

"Narushito Coating Waterproofing" is a modified asphalt sheet cold application method that does not use any organic solvents or open flames. To improve the workability of the Narufalto coating sheet method, "Narushito N" is used instead of non-woven fabric for the floor. It complies with JIS A 6013 modified asphalt roofing. 【Features】 ■ Environmentally friendly ■ Safe with no toxicity or flammability ■ Adhesion to wet substrates ■ High waterproofing capability due to asphalt ■ Followability to substrate expansion and contraction *For more details, please refer to the PDF materials or feel free to contact us.
