Foster® 85-75 DRION® Contact Cement
FOSTER DRION ® CONTACT CEMENT (Non-Flammable)
FOSTER DRION CONTACT CEMENT is a fast-setting, water- resistant adhesive for sealing the laps of vapor barrier jackets. Also used for bonding materials to a variety of surfaces in applications where immediate adhesion and high initial adhesive strength are required. Especially suited for bonding two impermeable surfaces. Non-flammable chlorinated solvents eliminate explosion and fire hazards during application.
DRION CONTACT CEMENT is ideal for bonding the laps and seams of polyester secondary vapor barriers on cryogenic insulation systems. It maintains a strong bond between layers of polyester film even at temperatures as low as -320 ° F (-196 ° ).
DRION CONTACT CEMENT must be applied to both surfaces, allowed to dry, and bonded with moderate uniform pressure. Gives strong immediate bond strength and allows bonding up to 1 hour after application. At temperatures below 50°F (10°C), drying time will be extended.
DRION CONTACT CEMENT meets NFPA 90A & 90B 25/50 requirements.
DRION CONTACT CEMENT is produced under the classification and follow-up service of Underwriter's Laboratories, Inc.
DRION CONTACT CEMENT contains no asbestos, lead, mercury, or mercury compounds.
Store between 40°F (4°C) and 100°F (38°C). Store above 70°F (21°C) at least 24 hours before use. Make certain this product is completely dry and the area free from solvent odor if food is involved. Always test plastic materials and painted surfaces for compatibility when using a solvent base product. Do not use with flexible PVC. 02/13
