LOCTITE UR 7221 - 30kg (one-component polyurethane adhesive) / Macroplast UR 7221
Product description:
LOCTITE UR 7221 is a solvent-free, moisture curing one component adhesive based on polyurethane. At room temperature and the required humidity in the joint sufficent strength will be obtained after approximately 2 to 4 hours. For faster curing LOCTITE UR 7221 can be cured in a heated press. Maximum temperature must not exceed 70°C. Further information about the product: biuro@woronko-kleje.pl
Directions for use:
Application Temperature : 10 to 35 °C.LOCTITE UR 7221 is applied to the substrate by spatula or doctor blade, but can also be applied by spraying or rolls. When bonding substrates without sufficient humidity or which are not moisture permeable, the required amount of moisture has to be provided by other methods. A proven procedure is the combined spraying of the adhesive simultaneously with water in a fine mist. In the case of separate adhesive and water mist application, the water must not be sprayed onto the bare metal but on the other substrate or ideally on the adhesive. Bonding surfaces should be brought together immediately after adhesive application, assuring sufficient contact pressure while curing, preferably in a press. Since LOCTITE UR 7221 cures by reaction with humidity, open containers must always be properly sealed and protected against moisture immediately after taking out the quantity needed. For the same reason we recommend to use up openedcontainers as soon as possible.
Storage:
When properly stored in a cool, dry location, with the container tightly closed when not in use, this product will have a shelf life of at least 9 months. Recommended Storage: 15°C to 25°C. Storage below 10 °C or greater than 50 °C can adversely affect product properties. LOCTITE UR 7221 is frost-sensitive.
