Case Studies

1. Project Overview

Item	Content
Project Name	Beijing City Administrative Sub-Center Staff Turnover Housing — North District Phase I & Phase II sub-plots; 18-block pilot delivered first (per Beijing Urban-Rural Construction Group)
Application Field	Residential / Public-Sector Staff Housing Sub-segments: Wood floor & panel bonding · Kitchen & bathroom wet-area sealing
Products Used	INGADA MS-35 — Instant Bond Construction Adhesive (wood floor & panel bonding) INGADA MS-88L — Crystal-Clear Mold-Proof Sealant (kitchen & bathroom wet-area sealing)
Project Location	Tongzhou District, Beijing — Lucheng Town Site bounded by Songliang Rd (E), Yudaihe St (S), Tongnan Rd (W), Tonghu St (N) ≈400 m from the Administrative Office Area · ≈1 km from Metro Line 6 Dongxiayuan Station

INGADA’s Role: INGADA supplied MS-35 instant-bond construction adhesive for prefabricated wood-floor and panel bonding, and MS-88L crystal-clear mold-proof sealant for kitchen/bathroom wet-area sealing, contributing to the North District project’s industrialized dry-process assembly workflow and its “move-in-ready” delivery standard for relocated government staff. The project was completed in Q3 2021.

2. Engineering Challenge

Challenge 1 — Low-VOC & “Move-In-Ready” Mandate

Relocated government staff required same-day occupancy after handover. Conventional on-site wet-mix cement and sand bedding generates months of VOC off-gassing (“放味” period of 3-6 months). The project mandated prefabricated dry-process assembly and sealants with French A+ / low-VOC certifications to compress the off-gassing window to a few days.

Challenge 2 — First-of-Kind (Reverse-Cast Porcelain) Façade at Residential Scale

The North District was the first large-scale residential deployment in China of the “瓷板反打” prefabricated façade technique: each external wall panel integrates structure, insulation, window frame and porcelain decorative skin in one factory-cast unit (pieces up to 7.6 t, ±2 mm installation tolerance). Adhesives and sealants touching these interfaces must bond across dissimilar substrates (porcelain · insulation · concrete · aluminum window frame) without inducing stress cracking in the cast porcelain skin.

Challenge 3 — Standardized High-Volume Wet-Area Sealing Across 1,700+ Apartments

Phase II alone delivered ~1,700 small-format units (35-70 m²) across 14 towers. Each kitchen and bathroom required consistent mold-proof sealing — typically the first failure point in public-sector housing. Sealants had to combine mold-proof V0 protection, crystal-clear aesthetics (so the substrate stays visible) and high-volume, repeatable application by assembly-line installers.

3. INGADA Solution

Challenge	Product	One-line Key Advantage
Wood floor & panel bonding — need high initial grab to eliminate clamps and accelerate the prefabricated flooring line (Challenge 1 & 3)	MS-35 Instant Bond Construction Adhesive	800 kg/m² instant grab · 3.2 MPa shear · zero-sag vertical bonding · -30°C to 100°C — supports clamp-free, support-free installation in an industrialized assembly line
Kitchen & bathroom wet-area sealing — must be low-VOC, mold-proof V0 and crystal-clear to preserve the substrate visual (Challenge 1, 2 & 3)	MS-88L Crystal-Clear Mold-Proof Sealant	Crystal-clear transparent finish · ≥8× mold resistance vs V0 standard · French A+ low-VOC · designed for glass shower enclosures and high-end wet-area substrates

4. Results & Outcomes

Outcome	Evidence / Metric
Project delivery on schedule	Phase I and Phase II of the North District delivered in 2018-2020; full North District Q3 2021 completion — matches INGADA case record “Completed in Q3 2021”
First-of-kind industrialized façade in residential China	“瓷板反打” prefabricated porcelain-façade technology — first large-scale residential deployment in China; integrated structure, insulation, window frame and decorative skin in single 2-7.6 t panels, ±2 mm installation tolerance
Move-in-ready interior finishing	Prefab dry-process finishing throughout 1,700+ units; “拎包入住” handover with smart locks; VOC off-gassing period compressed from typical 3-6 months to a few days
Wet-area sealing at residential scale	MS-88L deployed across kitchen and bathroom wet areas; ≥8× mold resistance vs V0 standard reduces re-sealing maintenance across the asset lifetime
