Tools Typically Required:
Plant mister bottle containing water.
Safety Precautions:
Wear gloves to avoid skin contact. Cured adhesive on bare skin will not come off immediately with washing and may cause skin to darken. Cured
adhesive and discoloration will come off of skin in about 3 days.
Preparation:
To ensure positive adhesion it is recommended to use adhesive above 41°F (5°C). For easier application, ensure the product temperature is 59°F
(15°C) or higher. Surfaces must be clean and free of frost, standing water, grease, dust and other contaminants. Pre-fit all materials and protect
finished surfaces. Be very careful not to allow PL Premium to cure on finished surfaces. Pierce inner seal with reverse end of cap.
General Application:
Apply adhesive to one surface of the material being bonded. Press the surfaces firmly together within 15 to 20 minutes. Materials may be
repositioned within 30 to 45 minutes after applying the adhesive. If bonding two non-porous surfaces (such as foam, metal or rigid fiberglass) or
under very dry conditions (less than 30% relative humidity), add water in the form of a very light or atomized spray from a plant mister bottle to the
extruded adhesive. Follow same procedure if bonding large size sheet goods. The repositioning time will then be reduced to less than 15 minutes.
Use mechanical support for 24 hours while the adhesive cures. Cure time is dependent upon temperature, humidity, porosity of substrate and
amount of adhesive used. Low temperature and humidity will slow cure time. When bonding EPS and XPS foam insulation, avoid cure and surface
temperatures above 90°F (32°C) as this may cause cavitation of the foam. User is responsible for determining suitable and acceptable results for
their intended project. Test before use.
.
Clean-up:
Clean tools and adhesive residue immediately with mineral spirits. Loctite® PL® Premium can be removed mechanically once cured. Solvents
have little to no effect on cured adhesive.
Not damaged by freezing. Store product at standard conditions which are defined as 72°F ± 4°F (22°C ± 2°C) and <50% relative humidity. After
completion of work, seal cartridge nozzle tightly with aluminum foil. Wrap the foil tightly around the nozzle and seal it with tape. Applying petroleum
jelly around the opening before sealing with aluminum foil can create a more airtight seal. Product cures with exposure to moisture. Use an
approved hazardous waste facility for disposal.
