- Application Instructions
Follow the procedure below for best results.
Surface preparation
Clean oil, dust, water, solvents, and other contaminants. Let dry fully.To coat by brushing
1. Apply an even coat to both surfaces using a brush or spatula.
2. Carefully position surfaces to be bonded and apply pressure.
3. Allow at least 24 hours at room temperature for full strength.ATTENTION! Unwanted cement adhesive residues should be cleaned immediately with acetone.
- Compatibility
Adhesion— The 8337 has excellent adhesion to metal, paper, cloth, foam, felt, rubber, and more. It is not compatible with contaminants like water, oil, and greasy flux residues that may affect adhesion. If contamination is present on the substrate, clean the surface first. This adhesive contains solvents that may not be compatible with some materials. It is recommended to test compatibly prior to use.

Viscosity: Brookfield viscometer at 60 rpm with LVT spindle #4
Working Life: Based on thin film application and porous materials. For non-porous materials, time can take several hours.
Full Strength: time varies depending on thickness, temperature, humidity, and porosity of materials being bonded.
Storage Temperature Limits: If stored above stated temperature, it may have a permanent effect on viscosity.

- Health, Safety, and Environmental Awareness
Please see the 8337-Liquid Safety Data Sheet (SDS) for more details on transportation, storage, handling and other security guidelines.
Environmental Impact: The 8337 formulation has a regulated volatile organic compound (VOC) content of 0% [0 g/L] by VOC-exemption.
Health and Safety: The liquid is flammable and should be kept away from flames and other ignition sources. As with most paint materials, avoid breathing in vapors or direct contact with the material and use in a well-ventilated area. It causes irritation and other symptoms like headaches, pain, as well as having long term exposure effects.
Wear safety glasses or goggles and disposable gloves to avoid exposures. Wash hands thoroughly after use. The cured coating presents no known hazard.
