Loctite 403 Instant Adhesive
High Strength Cyanoacrylate for Bonding Porous and Difficult Substrates
Product Overview
Loctite 403 is a one-component, high-viscosity, low-whitening, and low-odor alkoxy ethyl cyanoacrylate instant adhesive. This clear to straw-colored liquid cures via moisture contact and is engineered for rapid bonding of metals, plastics, and elastomers.
Key Features
- Fast, high-strength bonding for porous materials including wood, paper, leather, and fabric
- Rapid curing upon contact with surface moisture
- Excellent initial bond strength across multiple substrates
- High viscosity suitable for vertical or overhead application
- Low whitening and low odor for precision assembly applications
