Loctite 1690727 Structural Acrylic Adhesive 25ml

Product Description

The LOCTITE 1690727 is a two-part, acrylic-based structural adhesive sold in a 25ml unit. Known commercially as LOCTITE AA 330, it functions as a multipurpose structural bonder designed to join dissimilar substrate materials in a single assembly operation. The adhesive delivers medium- to high-viscosity application characteristics and provides good impact resistance once fully cured. Service temperature reaches up to 212 degrees F. Cure requires the use of LOCTITE SF 7649 activator, applied separately before bonding. Maintenance and assembly technicians working across light industrial, commercial, and trade applications typically handle this product.

LOCTITE 1690727 is suited for bonding dissimilar materials including PVC, phenolic compounds, and acrylic substrates. Common applications include assembly of tool handles, household appliances, sporting goods, and decorative trim components. The two-step activation process makes it appropriate for production line work and repair scenarios where a reliable, durable structural bond is required without mechanical fasteners. It performs across a range of environmental and mechanical stress conditions given its rated impact resistance and service temperature range.

Key Features

• Two-step acrylic structural bonding system requiring LOCTITE SF 7649 activator for cure
• Bonds dissimilar substrates including PVC, phenolic, and acrylic materials
• Medium- to high-viscosity formulation for controlled application
• Good impact resistance suited for assemblies subject to mechanical stress
• Service temperature rated up to 212 degrees F
• Multipurpose use across tool handles, appliances, sporting goods, and decorative trims

Compatibility

Designed for use with dissimilar substrate assemblies including PVC, phenolic, and acrylic compounds. Requires LOCTITE SF 7649 activator for proper cure activation.

Installation Notes

Apply LOCTITE SF 7649 activator to one substrate surface and allow it to flash off before applying the adhesive to the mating surface, following the manufacturer application instructions. Work in a well-ventilated area and use appropriate personal protective equipment when handling acrylic-based adhesive systems. Store the product according to label guidance to maintain shelf stability and performance.
