Features and Benefits

Durable – creates high strength bonds with or without primer; exhibits excellent primerless adhesive properties.

Convenient – single component requires no mixing; skins over quickly at room temperature, reducing cycle time.

Non-Sag – remains in position when applied on vertical or overhead surfaces, allowing for greater process flexibility

Easy to Use – easily dispensed; can be tooled and/or painted immediately.

Excellent Appearance – duplicates all types of OEM seals; holds brush marks without die back; weld-through with no burn back.

Chemically Resistant – solvent resistant when cured. Painting and most cleaning processes do not affect bond strength.

Temperature Resistant – uncured material can endure 225°F (107°C) for 60 minutes, and cured material can endure 325°F (163°C) for 60 minutes with no negative effect.

Environmentally Resistant – resists weathering and aging; provides excellent resistance to indirect UV exposure.


Duplicates factory seams where a non-sag, toolable/brushable seam sealer is required.
