Key features

Integral Water Repellency: Chemically reacts with cement matrix to provide deep, integral water repellent treatment.

Low Viscosity Fluid: Clear, low viscosity liquid (50-250 Cst) that easily disperses in water-based slurry.

Reduces Water Absorption: Dramatically decreases water ingress and capillary absorption in cementitious materials.

Prevents Efflorescence: Reduces transfer of water-soluble salts, preventing aesthetic issues like efflorescence.

Low VOC Emissions: Releases little Volatile Organic Content (VOC) upon chemical reaction with cement.

Versatile Applications: Suitable for fiber-reinforced cement boards, prefabricated components, and autoclaved lightweight cement.

Easy Integration: Can be used at 0.1-0.5% levels in cement formulations without diluting in solvents.

AI-Powered supplier vetting

SummaryHangzhou Silway New Material Technology Co., Ltd. is identified as a China-based limited company operating as both a trading company and manufacturer/factory, with chemical products focused on silicone additives, water repellents, release agents, antifoams, and related agricultural and industrial applications. It reports three production lines and annual productivity of 1,000 tons each for silicone adjuvants and water repellents. The supplier states that it has exported since 2017, derives 51%–70% of sales from exports, and holds self-managed import/export rights. Its stated R&D engineer experience and quality-control staffing are each below five, while its descriptions emphasize technological innovation and internal management. No certifications, after-sales capabilities, customization services, or detailed customer case studies are provided. Trade records show one transaction associated with each of two buyers, but these records are limited and do not establish broad customer performance.

Supplier typeThe supplier is identified as both a trading company and manufacturer/factory, while another record classifies it as a trading company. It is a limited company based in Hangzhou, Zhejiang, China, and operates in chemical-related trade.

R&D capabilityThe supplier explicitly states a long-term commitment to silicone innovation, science and technology, technological innovation, and improving market competitiveness. However, the reported total experience of R&D engineers is below five, and no patents, laboratories, or developed-project evidence is provided.

Production capacityThe supplier reports three production lines and annual productivity of 1,000 tons for silicone adjuvants plus 1,000 tons for water repellents. These stated production resources and capacities provide explicit evidence of manufacturing capability.

Client casesTwo trade records associate the supplier with one buyer in Uzbekistan and one buyer in Vietnam, with one transaction recorded for each. These entries provide limited evidence of customer activity but do not establish a broad, documented customer portfolio or successful case history.
