3M Hi-Strength 90 is a high-performance spray adhesive engineered for demanding bonding applications including plastic laminates, foam panels, fiberglass, metal, and wood. It delivers a strong, permanent bond to rigid substrates and is widely used in countertop laminate installation, cabinet fabrication, and composite panel assembly. The aerosol formula provides fast tack and good coverage, available in a 14.6 oz can. Designed for professional and industrial use where standard spray adhesives lack sufficient bond strength. Contains VOCs; use with adequate ventilation. Not recommended for lightweight paper or fabric applications where Super 77 is more appropriate.
What materials does Hi-Strength 90 bond?
Hi-Strength 90 bonds plastic laminates, high-pressure laminates (HPL), foam panels, fiberglass, metal, wood, and most rigid substrates. It excels in countertop laminate installation and composite panel assembly where a high-strength, durable bond is required.
Is Hi-Strength 90 the same as Super 90?
No, they are separate 3M products. Hi-Strength 90 is specifically formulated for laminate and rigid substrate bonding with an emphasis on peel strength. Super 90 is a general-purpose high-strength contact adhesive with a slightly different formulation and broader substrate compatibility.
How does Hi-Strength 90 compare to Super 77?
Hi-Strength 90 provides significantly greater bond strength and is suited for heavy or rigid materials like laminates and panels. Super 77 is formulated for lightweight materials such as foam, fabric, and paper. For laminate countertops or heavy bonding jobs, Hi-Strength 90 is the correct choice.
Do I need to spray both surfaces?
For maximum bond strength, apply Hi-Strength 90 to both surfaces, allow the adhesive to become tacky (typically 1 to 3 minutes depending on temperature and humidity), then press the surfaces together. Applying to only one surface reduces bond strength significantly.
Does Hi-Strength 90 require ventilation?
Yes. Hi-Strength 90 contains solvents and should be used in a well-ventilated area. Avoid prolonged inhalation of vapors, and keep away from open flames or ignition sources. Consult the Safety Data Sheet for full handling guidelines.
What size can does Hi-Strength 90 come in?
Hi-Strength 90 is available in a 14.6 oz aerosol can. This is the standard retail size; larger formats may be available through industrial distributors.
