Product Overview
NW Silane-Modified Polymer Waterproof Coating is a single-component, moisture-curing waterproof coating.
The products are divided into exposed-type and non-exposed-type varieties. The exposed-type uses silane-modified polyether as the base polymer and calcium carbonate as the primary filler, with the addition of cross-linking agents, stabilizers, and other additives. It reacts with moisture in the air to form a siloxane three-dimensional cross-linked structure; The non-exposed type uses a silane-modified polyether as the base polymer and is formulated with various additives, such as crosslinking agents and stabilizers, to produce a colorless, transparent, single-component, moisture-curing coating.
Product Categories
The product group consists of a single component.
Products are classified by application as exposed (W) and non-exposed (N).

Product Features
1. High solids content; contains 100% reactive compounds; quick surface drying time; no volumetric shrinkage; no sagging when applied to complex curved surfaces; saves construction time.
2. It can be applied to damp surfaces, is highly adaptable to various environmental conditions, and is convenient and easy to apply.
3. Solvent-free, plasticizer-free, NCO-free, zero VOC, and safe enough for use in drinking water.
4. A single-component, single-coat application is sufficient to achieve the required thickness, saving time, effort, and money.
5. It has excellent water resistance and is suitable for environments where it is frequently exposed to water.
6. The coating is dense and seamless, forming a skin-like structure that provides excellent waterproofing and corrosion resistance.
7. It adheres well to substrates such as concrete and metal color-coated steel, does not delaminate, and provides high bond strength.
8. It offers excellent resistance to aging and is suitable for exposed waterproofing projects. With a long service life, it represents a one-time investment that pays off for a lifetime, eliminating maintenance costs.
Construction Methods
Remove loose sand, debris, and metal rust particles from the substrate surface → Prepare the substrate → Apply a silane-modified polymer waterproof coating.
Important Notes
Do not perform construction work at temperatures below 0°C, in the rain, in extremely humid conditions, or in poorly ventilated areas.
Recommended Dosage
Exposed type: 1.5–1.6 kg/m²; non-exposed type: 0.3–0.5 kg/m².
Scope of Application
Exposed Type:
Suitable for use in all types of building waterproofing projects. It is particularly suitable for waterproofing sloped surfaces such as metal roofs, rooftops, and sloped edges.
Non-exposed type:
Suitable for home waterproofing, especially for waterproofing and repairs in kitchens, bathrooms, balconies, and patios; adheres well to tiles.
