ROBOND L-98D Plastic Adhesive

I am looking to turn Dow ROBOND L-98D into a production-ready adhesive for bonding plastic substrates in our new assembly line. My goal is to receive a complete, shop-floor-ready formulation that delivers strong, durable bonds on common engineered plastics (e.g., ABS, PET, PC) while staying within ROBOND L-98D’s recommended processing window.

You should already be comfortable working with water-borne acrylic systems and understand how to tailor viscosity, solids, and pH for slot-die, roll-coat, or spray application. Insight into suitable cross-linkers, plasticizers, defoamers, and wetting agents that play nicely with L-98D will be essential, along with guidance on surface prep for plastics, drying/curing profiles, and performance testing benchmarks (peel, shear, heat-age, humidity).

Deliverables I need from you
• A step-by-step adhesive formulation (percent-by-weight) built around Dow ROBOND L-98D
• Recommended mixing, coating, and curing parameters for plastic substrates
• A concise validation plan outlining test methods and pass/fail criteria for bond strength, heat/humidity resistance, and aging
• Safety and handling notes specific to the chosen additives

Acceptance will be based on clear, reproducible instructions and evidence that the proposed formulation meets the performance targets defined in the validation plan.
