Key Features

• OEM Replacement Solution: Engineered for the fast and effective replacement of original equipment manufacturer (OEM) flexible foams in automotive applications.
• High Expansion Rate: Features a 10:1 expansion ratio, allowing a small amount of material to fill large cavities and voids efficiently.
• Closed-Cell Construction: Provides excellent moisture and temperature resistance, ensuring durability and consistent performance in automotive environments.
• Non-Shrinking Formula: Composed of 100% solids, this urethane foam prevents shrinkage, thereby helping to avoid drawing in or wrinkling body panels over time.
• Rapid Curing: Cures in approximately one hour, which helps maximize work time and enhance vehicle throughput in repair shops.
• Easy Application: Designed for use with 3M™ Automix™ applicators, ensuring straightforward mixing and precise application directly into automotive cavities.

Applications

• Replacing flexible foam in automotive body structures such as door skins, door cavities, roof bows, and intrusion beams.
• Filling voids and gaps within body panels and other auto body closed cavities.
• Reducing Noise, Vibration, and Harshness (NVH) by providing sound deadening and acoustic insulation in vehicle interiors.
• Restoring vehicles to pre-accident condition during collision repair by replicating OEM flexible foams.
• Providing structural support in specific areas of the vehicle.

Benefits

• Restores Original Vehicle Integrity: Effectively replaces factory-installed foams, helping to restore vehicles to their original condition and maintain structural integrity.
• Enhances Driving Comfort: Significantly reduces cabin noise and dampens vibrations, contributing to a quieter and more comfortable driving experience.
• Optimizes Repair Efficiency: Its high expansion rate saves material costs, while the rapid 1-hour cure time streamlines repair procedures and increases productivity.
• Ensures Lasting Performance: The closed-cell, non-shrinking formulation resists moisture and temperature, offering durable performance without panel deformation.
• Simplifies Automotive Repair: Provides a convenient, foam-in-place material that mixes and applies easily with compatible applicators, making OEM foam replacement simple and cost-effective.
