Lord AP-134 Adhesion Enhancer/Surface Modifier for Glass, Ceramics, Metals, e-Coatings

LORD® AP-134 adhesion enhancer/surface modifier is a one-coat, moisture-cure primer used to promote adhesion to a variety of polar substrates. These substrates include architectural and automotive glass, steel, aluminum, brass, e-coated metal, glass fabric, ceramic tile, vitrified clay pipe, concrete and some plastics.

Features and Benefits

• Versatile – provides a wide range of product applications by functioning as a primer to a variety of polar substrates and as an adhesive for reaction injection molding (RIM) of polyurethane to glass.
• Easy to Apply – applies easily by spray, dip or polyester felt applicator.
• Convenient – requires only a single coat for most applications, reducing labor, solvent usage, inventory and shipping costs.

Applying / Drying / Curing 

Allow adhesion enhancer/surface modifier to hydrolyze in moist air (50-80% RH) at 70-90°F (21-32°C) for 1-2 hours. To reduce the hydrolysis time, parts can be cured in an oven at 190°F (88°C) for 3 minutes. Air being drawn into the oven should be 50-80% RH. The cure time can vary depending on the mass of the part being primed. Large parts require more time in an oven to complete cure, due to the heat sink effect ofthe larger mass.

For best adhesion, apply top coat or encapsulating polymer within 24 hours after adhesion enhancer/surface modifier cures.

Clean Up

Use toluene or alcohol to remove wet adhesion enhancer/surface modifier. Remove cured adhesion enhancer/surface modifier by mechanical abrasion, blasting or grinding methods.

Shelf Life
Shelf life is one year from the date of shipment when stored in a dry, well-ventilated area at 70-80°F (21-27°C) in the original, unopened container.
After opening, protect adhesion enhancer/surface modifier from moisture contamination. If using a 55-gallon drum, install a desiccant cartridge to dry the air drawn into the drum when drawing off the product.
