About IRS 3103 Structural Polyurethane Adhesive
Also available to buy online at
IRS 3103 Structural Polyurethane Adhesive is a general-purpose two-part black adhesive which offers excellent bond strength to a wide range of substrates including plastics, metals and composite materials. It is non-sagging when dispensed, allowing application on vertical substrates, and offers excellent gap-filling properties.
IRS 3103 cures to handling strength in minutes, and reaches enough cure to be sanded after 30 minutes. Once cured, it forms a durable polymer which is resistant to moisture, fuel, solvents and chemicals.
IRS 3103 is supplied in pre-measured, side-by-side double syringe cartridges and includes static mixing nozzles for straightforward application.
