Permabond TA4631 Polyolefin (PE, PP), Nylon & Rubber Bonder, Clear Color, Thin Viscosity 12-18 min Acrylic MMA Adhesive White

Product Name

Permabond TA4631 Polyolefin (PE, PP), Nylon & Rubber Bonder, Clear Color, Thin Viscosity 12-18 min Acrylic MMA Adhesive White

Brief Description

Permabond TA4631 is a two-part, 1:1 mix ratio, no-odor acrylic (MMA) adhesive specifically engineered for bonding low surface energy plastics such as polypropylene (PP) and polyethylene (PE), including HDPE, without the need for primers or expensive surface treatments. It also effectively bonds nylon, rubber, metals, and composite materials, making it ideal for dissimilar surface bonding applications.

Popular Applications & Uses

- Bonding low surface energy plastics like polypropylene and polyethylene.- Attaching trim, moldings, and decorative plastic components in automotive interiors and exteriors.- General assembly of plastics, metals, and composites.- Applications in electronics and consumer goods.- Medical device assembly.- Bonding rubber and elastomers.- Structural bonding of various materials, including dissimilar surfaces.

Industries that Commonly Use It

- Automotive Service/Repair- General Manufacturing- LED/Electronics- Marine- Medical Device/ Prosthetics- Metal Fabrication- Plastic Fabrication- Transportation/ Specialty Vehicle

Special and Unique Features

- No odor formula, enhancing operator comfort and suitability for odor-sensitive environments.- Bonds polyolefins (PE, PP, HDPE) without the need for primer or surface treatments like flame, plasma, or corona treatment, offering cost and process savings.- Adhesion to a wide variety of substrates, including difficult-to-bond low surface energy plastics, metals, and composites.- Full cure at room temperature.- Excellent impact and shear strength.- Great water resistance and can bond underwater.- Ideal for bonding dissimilar materials.- Lower viscosity / flowable formula, suitable for joints with smaller gaps.
