Storage condition
Store in a cool, dry, cool place below 27 degrees C, from the production date, the storage period is 9 months, please pay attention to the production date of the product packaging.
887 dry hanging stone plastic A, B components must be sealed storage, but also could not contact the air, the use should be immediately sealed to prevent contact with air curing failure.
Usage method
Stone and metal contact parts must be clean, no dust, water and oil;
Clean the greasy dirt on the metal;
887 dry hanging stone glue according to the quality than 11:1 (such as A component 2.75kg with B component 250g) for matching operation. When mixed with B were divided into A component by glue gun, stir evenly with a wooden stick or a stirring drill (mixing with butterfly experimental methods must be used in a hybrid test), it should be used within 30 minutes. About 30 minutes after the component A, B mixed evenly, the mixture become to semi - curing state, after two hours become harden, curing totally after 24 hours. (Note: curing speed can be adjusted according to user requirements for a certain).
Using restrictions
Could not be used for back bolt type stone curtain wall;
Could not be used as structural sealant;
Should not be used for long-term immersion or wet place all year round.
