General Purpose Structural Adhesives for Limitless Design

LOCTITE HY 4090 and LOCTITE HY 4080 – Expanding your Design Solutions.

Combining speed, strength and durability, LOCTITE General Purpose Structural Adhesives help you reduce weight, reduce material costs, and increase reliability with improved health and safety for workers.

LOCTITE General Purpose Structural Adhesives bond a variety of materials, such as metals, including steel, composites, most plastics and rubbers. Enhanced properties include fast fixture to speed up production; excellent resistance to shock loading for assemblies needing high strength and low blooming to maintain aesthetic appeal on opaque materials.

Improved health and safety benefits include non-flammable, non-corrosive, isocyanate-free and low odor, making LOCTITE General Purpose Structural Adhesives an ideal alternative to traditional 2-part Methyl Methacrylate Adhesives (MMA) and Acrylic adhesives.

Please note: Henkel recommends that you test all adhesive applications under simulated or actual end-use conditions to ensure the adhesive meets or exceeds all required product specifications.

CHALLENGE 1 - Bonding stainless steel to plastic on a sign

Previous assembly method: Hand cut double sided tape.
Limitations: Production delays; tape strength for PMMA plastic is poor; loss of trim pieces lowered customer satisfaction; visibility of tape detracted from sign aesthetics.

Solution: LOCTITE HY 4090

Adhesive is dispensed into a groove on the plastic sign and the stainless steel trim piece is hand pressed into the groove to complete assembly.

LOCTITE BENEFITS – Bonding stainless steel to plastic on a sign

Easy dispensing and quick fixture reduces assembly time and labour.
Superior bond strength prevents trim loss.
Colorless adhesive resolves previous appearance issues.

CHALLENGE 2 – Bonding stainless steel grid to plastic batonnet in aromatherapy bath

An adhesive that cures in low humidity environments is required.
An adhesive that can bond both plastics and metal to keep inventory costs down.
A reliable solution is needed to reduce rework and scrap of defective parts.


Solution: LOCTITE HY 4090

Bath cartridge is assembled with one adhesive.

LOCTITE BENEFITS – Bonding stainless steel grid to plastic batonnet in aromatherapy bath

Eliminates issues from low seasonal plant humidity.
Single adhesive bonds both materials which reduces inventory and increases production output.
Reliable bond dramatically reduces defective parts and scrap.
