MOUNTSHIP™ M200

MDI-Based Polyurethane Adhesive

Need strong, cost-effective bonding for dark-colored tracks or base layers?
→ MDI-based PU adhesive delivers high strength, REACH compliance, and proven durability — ideal for budget-conscious large projects.

Product Advantages

Safety First

TDI-free, formulated with safer MDI; free MDI content < 0.1% after curing — fully compliant with REACH, RoHS, and other international environmental and health standards.

Superior Bonding

High crosslink density delivers >2.0 MPa adhesion to both EPDM and concrete — remains intact under long-term loading, high-pressure washing, and repeated thermal cycles (no delamination or granule loss).

Efficient Application

Fast initial tack and rapid strength development shorten project timelines; 1K moisture-cure system requires no mixing or metering — simple, fast, and reliable on-site application.

Cost-Effective Performance

Delivers >90% of aliphatic PU performance at a significantly lower cost — ideal for dark-color systems, school tracks, and community sports courts where value and volume matter.

MOUNTSHIP™ A950

Aliphatic Anti-Yellowing PU Adhesive

The Premium Standard for Safety & Aesthetics Zero yellowing for 2+ years on white/light EPDM surfaces; near-odorless, EN 71-3 certified. Ideal for luxury playgrounds, hospitals, and indoor children’s zones.

Product Advantages

Anti-Yellowing Excellence

Pure aliphatic isocyanate structure — zero benzene rings, superior UV resistance. Keeps white and light-colored EPDM surfaces bright and clean for 2+ years, with no yellowing.

Child-Safe & Non-Toxic

Near-odorless during curing and aging; rigorously tested and certified to REACH and EN 71-3 (Toy Safety) standards.

Enhances Color Brilliance

Preserves true color vibrancy of EPDM granules — ideal for bold, light, or custom Pantone® hues. The perfect partner for high-visibility, high-aesthetic projects.

Premium Project Standard

The preferred binder for high-end applications: luxury residential play zones, theme parks, urban plazas, hospitals, and indoor children’s areas — where safety, aesthetics, and longevity are non-negotiable.

FAQ

Q: What are the ideal temperature and humidity conditions for applying PU adhesive?

A: Recommended: 10–40°C ambient temperature, substrate dry, and ≤75% relative humidity. For cold conditions (<10°C), pre-warm the adhesive to 25°C to improve flow (avoid open-flame heating).

Q: What’s the open time for MDI vs. aliphatic PU adhesives?

A: SAFIBOND™ M200 (MDI-based): ~25–35 min at 25°C — fast initial tack, ideal for large-area, high-speed installation.
SAFIBOND™ A950 (Aliphatic): ~40–60 min at 25°C — longer working time, perfect for intricate designs or multi-color zones.

Q: What’s the recommended mixing ratio with EPDM granules? How to ensure homogeneity?

A: Typical ratio: 1 part adhesive : 5–7 parts EPDM (by weight). Adjust based on granule size, polymer contentand layer thickness.
Mixing best practice:
① Dry-mix EPDM granules for 2 min;
② Add adhesive gradually, mix ≥3 min;
③ Rest 2–3 min before laying.

Q: How can I verify compliance with REACH, RoHS, EN 71-3?

A: We provide SGS test reports (, including:
• Free MDI < 0.1%
• Full 169-SVHC screening (REACH)
• Heavy metals (Pb, Cd, Hg, etc.) within RoHS & EN 71-3 limits

Q: How to choose between SAFIBOND™ M200 and SAFIBOND™ A950?

A: Quick Selection Guide
1️ Color? → White / light / multi-color design? → A950
2️ Application? → Kindergartens, hospitals, luxury residential? → A950
3️ Budget & Scale? → Large public projects + dark systems + cost-sensitive? → M200

Q: Is SAFIBOND™ compatible with other brands’ EPDM granules?

A: Yes — compatible with most EPDM granules on the market.
For optimal performance & warranty support, we strongly recommend pairing with SAFIXGRAN™ series — crosslink compatibility fully validated.
