Meeting ANSI Standards in the U.S. Market: The VAE RDP Advantage for Large-Format Tile Projects

The U.S. construction boom is dominated by large-format tiles and thin porcelain panels. Specifiers demand adhesives meeting ANSI A118.15 (improved performance) for these heavy, non-porous materials. Ordinary C2 adhesives often fail the rigorous shear bond and water immersion tests. Our VAE-based RDP is your direct path to meeting these stringent U.S. standards without over-formulation.

The U.S. Specification Challenge
American architects and contractors rely on ANSI standards, not just EN classifications. To win high-rise commercial and luxury residential projects, your adhesive needs:

• ANSI A118.15: Superior shear bond strength on large, heavy tiles.
• ANSI A118.11: High-performance for exterior and wet-area applications.
• Consistent results across the U.S. climate spectrum — from the humid heat of Florida to the freezing winters of Minnesota.

Our VAE RDP: The ANSI Compliance Engine

1. Superior Shear Bond for Large-Format Tiles
Our VAE polymer forms a flexible, tenacious film that grips the back of large porcelain panels completely. This ensures high shear bond strength that exceeds the ANSI A118.15 requirement, preventing the tile “creep” and debonding common with rigid mortars.

• Shear bond strength (ANSI A118.15): >350 psi (standard >50 psi)
• Full coverage on 24″ x 48″ tiles, confirmed by glass plate testing.

2. Flexibility for Exterior and Wet Areas (ANSI A118.11)
The low Tg of our VAE RDP (-5 to +5°C) provides the flexibility needed for freeze-thaw durability in Northern states and dimensional stability under the Southern sun. Our system consistently passes the 100-cycle freeze-thaw test and prolonged water immersion.

• Tensile adhesion after water immersion: >150 psi
• Freeze-thaw bond retention: >90%

3. Partnered with an HPMC for Extended Open Time
Our HPMC 15000 mPa·s provides a stable, extended open time of 30+ minutes at 70°F (21°C) and excellent water retention at low dosage, giving installers the workability they demand for precise tile alignment.

U.S. Market Success Path
A tile adhesive manufacturer in Texas switched to our VAE RDP system to meet the new ANSI A118.15 spec for a high-rise condo project. They achieved a 380 psi shear bond, passed every wet and thermal cycle test, and secured the multi-million-dollar contract.
