Kastar 4000 Silicone Waterproof Coating: CE-Certified Specifications and Performance for Building Waterproofing
Introduction
Kastar 4000 Silicone Waterproof Coating is a one-component, UV-resistant silicone waterproof coating designed for long-term building protection. Manufactured by Kastar Adhesives Technologies Co., Ltd., a Chinese OEM/ODM factory founded in 1998 with a 150,000 m² facility and an annual output of 300,000 tons, this product has obtained CE certification for the European market. This article provides the technical parameters, certification details, and application evidence that procurement professionals and distributors need during the research and evaluation stages.
Problem Definition: Why Reliable Waterproofing Matters
Building envelopes—roofs, exterior walls, basements, and expansion joints—are constantly exposed to UV radiation, rain, freeze‑thaw cycles, and structural movement. Inadequate waterproofing leads to leaks, mold growth, structural deterioration, and costly repairs. Buyers require a coating that offers long‑term durability, proven compliance with regional standards (e.g., CE marking for Europe), and consistent performance under extreme conditions.
Industry Background
The global silicone waterproof coating market is shifting toward high‑solids, 100% silicone formulations that outperform acrylic or polyurethane alternatives in weatherability and service life. Regulatory bodies in Europe and North America increasingly demand third‑party certification—such as CE marking under EN standards—to ensure fitness‑for‑purpose. For distributors and contractors, specifying a CE‑certified product simplifies project approval and reduces liability.
Detailed Solution: Kastar 4000 Silicone Waterproof Coating
Kastar 4000 Silicone Waterproof Coating is a single‑component, moisture‑curing product that forms a seamless, elastomeric membrane. Its key technical parameters, verified by the manufacturer, are:
- Solid Content: 98%
- Elongation at break: ≥200%
- Tensile strength: ≥1.2 MPa
- UV resistance: 1,000 hours without cracking or peeling
- Operating temperature range: −80 °C to +180 °C
- Outdoor service life: ≥25 years
The product holds CE certification (certificate number ICR/VC/HS260188) issued by ICR, valid from January 16, 2026 to January 15, 2031. This certification confirms compliance with European standards EN 15651‑1:2017, EN 998‑1:2016, and EN 13300:2001+AC:2002, covering sealants, rendering mortars, and interior/exterior coatings respectively.
Step-by-Step Application Guidance
- Surface preparation: Clean and dry the substrate; remove loose particles, oil, and old coatings.
- Priming (if required): Apply a compatible primer to porous surfaces.
- Application: Use a brush, roller, or spray gun. For cracks and joints, embed reinforcing fabric into the first coat.
- Curing: Allow the coating to cure via atmospheric moisture. Avoid water contact during the first 24 hours.
- Inspection: Check for uniform coverage and film thickness; apply a second coat if necessary.
Use Cases
- Roof waterproofing – flat and sloped roofs exposed to UV and rain.
- Exterior wall waterproofing – prevents moisture ingress and efflorescence.
- Expansion joint sealing – accommodates structural movement.
- Basement and underground structure waterproofing – resists hydrostatic pressure.
- Bathroom and balcony waterproofing – seamless membrane for wet areas.
