Everbond Ultra Clear Brush Contact

For automotive upholstery, furniture manufacturing, and commercial assembly where visible glue lines must be avoided, Everbond Ultra Clear Brush Contact is a thixotropic contact adhesive that dries completely clear. This one-component polychloroprene formula provides high initial strength and rapid bonding, making it suitable for secure assembly even when working with trim materials with high spring-back forces.

How it works

Everbond Ultra Clear Brush Contact functions via rapid solvent evaporation. Applied evenly to both mating surfaces, the thixotropic liquid flashes off in approximately 3 to 5 minutes to form a tacky film. When the two surfaces are pressed together under strong pressure, they form an instant, high-strength bond. Because it dries clear, it prevents unsightly joint lines on exposed seams, such as those on neoprene drink coolers, PUR foams, and fine upholstery fabrics.

Numbers that matter

• 6 to 8 m² per litre consumption: Provides a predictable coverage floor for estimating material requirements across flat substrates.
• 3 to 5 minutes dry time: Extremely fast open-time window before bonding, keeping assembly lines and upholstery workshops moving.
• 10°C to 35°C application range: The safe temperature envelope for applying the adhesive to prevent pre-cure or condensation-related failures.
• 120°C heat resistance: Tested to withstand temperatures in excess of 120°C when used with the 2P additive, protecting the bond against high-heat cabin environments in transport vehicles.

Where to use it

This adhesive bonds a broad range of materials, particularly in the manufacturing of transport vehicles and commercial upholstery. Suitable substrates and applications include:

• Materials: Timber, MDF, particleboard, rubber sheets, plastic laminates, leather, glass, metal sheets, fabric, and both cloth-backed and polyester-backed vinyl.
• Vehicle Assembly: Adjoining steps, wheel arches, seat brackets, side walls, cover trims, and edging profiles.
• Upholstery & Manufacturing: Auto upholstery, furniture upholstery, PUR foams, textiles, and neoprene drink coolers.

Limitations

• Temperature floor: Do not apply in temperatures below +10°C. Cold temperatures can cause condensed water to form on the wet adhesive layer, preventing a proper bond.
• Application risks: Do not apply excessive adhesive, allow the product to pool, or join the substrates too early. Entrapped solvents from wet adhesive pools will result in blistering, a weak bond, or complete joint failure.
• Porous materials: For highly open-weave or porous substrates, Adheseal spray contact is recommended instead of brush application to prevent the adhesive from bleeding through to the face of the material.
• Container life: Once the container is opened, the material must be used up in a short time.

Application

All adhesion surfaces must be clean, dry, and free of oils, grease, dust, and friable material.

Apply the adhesive evenly to both surfaces using a suitable roll-coater, tooth-comb, brush, or notched trowel. Avoid forming pools of adhesive in corners or depressions. Wait 3 to 5 minutes until the adhesive is touch-dry, then bring the two materials together with strong, even pressure. Clean up wet or excess adhesive with acetone.
