KingGlue 520 Adhesive is an air-drying contact adhesive that is excellent for joining seams and butt joints of Kingflex Pipe and Sheet Insulation for line temperatures up to 250°F(120°C). The adhesive may also be used to apply Kingflex Sheet Insulation to flat or curved metal surfaces that will operate at temperatures up to 180°F (82°C).
KingGlue 520 will make a resilient and heat-resistant bond with many materials where the use of a solvent-base neoprene contact adhesive is suitable and desirable.
Application Guidelines
Mix well, and apply only to clean, dry, oil-free surfaces. For best results, the adhesive should be brush-applied in a thin, uniform coat to both bonding surfaces. Allow the adhesive to tack prior to joining both surfaces. Avoid open time of more than 10 minutes. KingGlue 520 Adhesive bonds instantly, so pieces must be positioned accurately as contact is made. Moderate pressure should then be applied to the entire bonding area to insure complete contact.
Temperature Recommendations
It is recommended that the adhesive be applied at temperatures above 40°F (4°C) and not on heated surfaces. Where application between 32°F and 40°F (0°C and 4°C) cannot be avoided, exercise more care in applying the adhesive and closing the joint. Applications below 32°F (0°C) are not recommended.
High Temperature Operation
Where lines and tanks that are insulated and will operate at hot temperatures, KingGlue 520 Adhesive must cure a minimum of 36 hours at room temperature to attain heat resistance for insulated pipe to 250°F (120°C) and insulated tanks and equipment to 180°F (82°C).
Curing Requirements
Adhesive-bonded seams and joints of Kingflex Pipe Insulation must cure before finishes are applied. Where the insulation is installed by adhering seams and butt joints, the adhesive must cure 24 to 36 hours.
Adhesive-bonded seams and joints of Kingflex Sheet Insulation must cure before finishes are applied. Where the insulation is installed by adhering seams and butt joints only, the adhesive must cure 24 to 36 hours. Where the insulation is installed against surfaces with full adhesive coverage, requiring wet adhesive at joints, the adhesive must cure seven days.
DANGER / SAFETY WARNINGS
Extremely flammable mixture; vapors may cause flash fire; vapors may ignite explosively; prevent buildup of vapors—open all windows and doors—use only with cross ventilation; keep away from heat, sparks, and open flame; do not smoke; extinguish all flames and pilot lights; and turn off stoves, heaters, electric motors, and other sources of ignition during use and until all vapors are gone; close container after use; avoid prolonged breathing of vapor and prolonged contact with skin; do not take internally; keep away from children.
Not for consumer use. Sold only for professional or industrial application.
Frequently Asked Questions (FAQ)
Q What is the temperature limit for KingGlue 520 Adhesive?
KingGlue 520 Adhesive is designed for joining seams and butt joints of pipe and sheet insulation for line temperatures up to 250°F (120°C). It can also apply sheet insulation to flat or curved metal surfaces operating at temperatures up to 180°F (82°C).
Q What is the recommended application temperature?
It is recommended to apply the adhesive at temperatures above 40°F (4°C) and not on heated surfaces. If application between 32°F and 40°F (0°C and 4°C) is unavoidable, extra care must be taken. Applications below 32°F (0°C) are not recommended.
Q How long does the adhesive take to cure?
For seams and butt joints on pipe and sheet insulation, the cure time is 24 to 36 hours. For full adhesive coverage installations requiring wet adhesive at joints, the adhesive must cure for seven days. For high-temperature pipe/tank operations, it must cure for at least 36 hours at room temperature.
Q What is the maximum open time when applying KingGlue 520?
You should allow the adhesive to tack prior to joining surfaces, but avoid an open time of more than 10 minutes. Because it bonds instantly, pieces must be positioned accurately upon contact.
Q Can this adhesive be used by individual consumers?
No, KingGlue 520 Adhesive is not intended for general consumer use. It is sold exclusively for professional or industrial applications.
Q What safety precautions must be taken during application?
Since this is an extremely flammable mixture, you must prevent the buildup of vapors by opening all windows and doors for cross ventilation. Keep it away from heat, sparks, open flames, and other ignition sources. Avoid prolonged inhalation of vapors and contact with skin.
