Silway 742 - Silicone Waterproof
Silway 742 - Silicone Waterproof is a hydrogen silicone oil emulsion produced by Hangzhou Silway New Material Technology Co.ltd., based in Hangzhou, Zhejiang, China. The formulation creates a hydrophobic barrier that repels water while allowing the substrate to breathe. It is supplied as a milky white emulsion suitable for direct application on roof coatings, masonry, clay and timber surfaces. The product is marketed as low‑VOC and suitable for demanding construction environments.
Typical technical data for the emulsion include a solids content of 30‑35 % by weight and a viscosity range of 1 000‑3 000 cSt at 25 °C, which facilitate easy mixing and uniform film formation. The recommended wet film thickness is 100‑200 µm, delivering a durable water‑repellent layer after curing. Standard curing time is approximately 24 hours at 20 °C, and the VOC content is ≤ 50 g/L, meeting many environmental regulations. The emulsion conforms to common industrial standards for waterproofing agents.
Construction contractors, roofing specialists and manufacturers of pre‑coated panels commonly specify Silway 742 for long‑term protection against water ingress. Trade terms often involve FOB or CIF from the port of Shanghai, with packaging offered in 20 L drums or 200 L intermediate bulk containers. The supplier indicates flexibility in minimum order quantities, but exact thresholds should be confirmed directly. Buyers should verify the product’s ISO or SGS certification status and request a safety data sheet before procurement.

Sourcing Silway 742 - Silicone Waterproof from Hangzhou Silway New Material Technology Co.ltd. - China Import Guide
Before finalising a purchase, confirm the solids content, viscosity and VOC levels against the technical data sheet provided by the supplier. Request a sample batch to evaluate film formation, colour consistency and breathability on a representative substrate. Ask for copies of any ISO or SGS certificates, as well as a detailed safety data sheet, to ensure the product meets the regulatory requirements of your market.
When arranging shipment, clarify whether the transaction will be on FOB or CIF terms and identify the preferred Chinese port, typically Shanghai, for loading. Discuss container loading plans, including the number of 20 L drums or 200 L IBCs that can be accommodated in a standard 40‑foot container, to avoid unexpected freight costs. Confirm payment method, such as a confirmed letter of credit, and negotiate a schedule that aligns with your project milestones and cash‑flow considerations.
Implement a quality assurance protocol that includes third‑party inspection of the sealed containers upon arrival, verification of the product’s pH and viscosity, and measurement of the applied film thickness on a test panel. Ensure that the supplier provides a full set of documentation, including the material safety data sheet, test certificates and a commercial invoice, to facilitate customs clearance and downstream quality control. Maintaining these checks helps guarantee that the waterproofing system performs as intended throughout its service life.
