LORD 320/322 Epoxy Adhesive for SMC, Metal, Rubber and FRP Bonding

LORD 320/322 Epoxy Adhesive is a two-component structural epoxy adhesive system designed for strong bonding, sealing and repair on automotive SMC, prepared metals, rubber, FRP, polyester thermosets, thermoplastics and many industrial materials. It is suitable for automotive composite parts, truck panels, fiberglass reinforced plastic components, metal brackets, rubber-to-metal assemblies, molded panels and general industrial bonding applications. For manufacturers, repair users, distributors and industrial buyers, this adhesive provides a practical solution when high strength, impact resistance and environmental durability are required.

LORD 320/322 Epoxy Adhesive Product Overview

LORD 320/322 Epoxy Adhesive is supplied as a two-part system consisting of LORD 320 resin and LORD 322 hardener. LORD 320 resin is an off-white paste, while LORD 322 hardener is a grey paste. After mixing, the adhesive becomes a grey paste and cures into a durable grey epoxy bond line. The system can be cured at room temperature or heat cured for faster processing, giving production users flexibility according to part size, fixture time and process requirements.

This adhesive is especially known for primerless adhesion to automotive sheet molded compounds. SMC and composite parts are widely used in vehicle panels, hoods, body components, truck parts and industrial molded structures. LORD 320/322 Epoxy Adhesive helps bond these materials without requiring a primer in many SMC applications, reducing process steps and improving production efficiency. It also provides excellent adhesion to prepared metals, cured rubber, FRP and selected thermoplastic materials when proper surface preparation is used.

Key Benefits of LORD 320/322 Epoxy Adhesive

LORD 320/322 Epoxy Adhesive provides strong load-bearing performance and durable cured properties. The cured adhesive offers impact resistance down to -40°C and helps inhibit crack propagation, making it suitable for structures exposed to shock, vibration and demanding mechanical stress. This is important for automotive and industrial assemblies where the adhesive bond must remain reliable during movement, temperature changes and service exposure.

The adhesive system is solvent-free, nonflammable and virtually odorless according to Parker LORD product information. It also resists humidity, sunlight, salt spray and temperature extremes. For automotive production, maintenance repair and composite bonding, this balance of mechanical strength and environmental resistance helps improve long-term assembly reliability. The cured adhesive is also resistant to many solvent-related conditions, while anti-corrosion processes such as phosphatizing and ELPO e-coat are listed as not affecting the adhesive or bond strength under TDS guidance.

LORD 320/322 Epoxy Adhesive for Automotive SMC Bonding

Automotive SMC bonding is one of the main uses of LORD 320/322 Epoxy Adhesive. Sheet molded compound parts often require a durable adhesive that can bond composite panels while maintaining impact resistance and dimensional stability. This product can be used for SMC-to-SMC assemblies, vehicle body panels, composite repairs, structural supports and molded component bonding. The recommended bond line thickness for general use is approximately 0.51–0.76 mm, helping users maintain consistent adhesive thickness and reliable wetting between parts.

LORD 320/322 Epoxy Adhesive for Metal, Rubber and FRP Assembly

LORD 320/322 Epoxy Adhesive can also be used for prepared metals, rubber, fiberglass reinforced plastics and mixed-material assemblies. Metal surfaces should be properly cleaned, and oxidized metal may require abrasion followed by a second cleaning step. For cured rubber, LORD 7701 adhesion enhancer may be used; for glass and ceramic surfaces, LORD AP-134 adhesion enhancer may be used to promote adhesion. These preparation steps help support stronger and more consistent bonding performance in industrial production.

Industrial Applications and Online Buyer Value

From a network promotion perspective, this product matches buyer search needs such as LORD 320/322 Epoxy Adhesive, SMC bonding adhesive, automotive composite adhesive, FRP bonding epoxy, rubber to metal adhesive, high strength epoxy adhesive and two component epoxy glue. These keywords are commonly used by professional buyers who need a technical adhesive for automotive, composite and industrial assembly rather than a general-purpose repair glue.

For distributors and online stores, LORD 320/322 Epoxy Adhesive can be promoted to automotive component manufacturers, composite part factories, truck repair users, FRP product manufacturers, metal fabrication workshops, rubber bonding users and industrial maintenance teams. A product page should clearly highlight two-component epoxy technology, primerless SMC adhesion, room temperature or heat cure options, impact resistance, environmental resistance, high temperature postbake resistance, solvent-free formula and broad substrate compatibility. These selling points help improve search relevance and increase inquiry conversion.

How to Use This Two-Component Epoxy Adhesive

Before application, all bonding surfaces should be clean, dry and free from soil, oil, grease, fingerprints, dust, mold release agents, rust and loose particles. Mix LORD 320 resin and LORD 322 hardener thoroughly until the color and consistency are uniform. Apply the mixed adhesive by automatic meter-mix dispensing equipment, cartridge, spatula, stiff brush or trowel. Join the parts carefully to avoid trapped air and apply enough pressure to ensure good wetting on both surfaces. Do not over-clamp, because excessive pressure can squeeze too much adhesive out of the joint.

Why Choose LORD 320/322 Epoxy Adhesive

LORD 320/322 Epoxy Adhesive is a practical choice for users who need strong bonding, primerless SMC adhesion and durable performance in automotive and industrial applications. It supports SMC bonding, FRP bonding, metal bonding, rubber bonding, composite repair and mixed-material assembly. With its two-component epoxy structure, flexible cure options, environmental resistance and excellent load-bearing performance, this adhesive provides a professional bonding solution for demanding manufacturing and repair applications.
