AA500 is a one-component sealant that solidifies after contact with water vapor in the air. It is easy to operate and does not require stirring before use. It can be applied using a manual or pneumatic glue gun. Before applying the sealant, ensure that the surface of the substrate is dry and free of oil, grease, dust, etc. After applying the sealant, the sealant surface must be trimmed before the sealant surface forms a crust. When designing the glue joint, avoid three-sided bonding of the sealant.
Cannot be used for structural assembly
Cannot be used on surfaces that will leak plasticizers or solvents, which may cause the sealant to be damaged
Not recommended for use in completely sealed spaces, which may result in incomplete curing due to lack of water vapor
Not recommended for long-term immersion in water
Not recommended for structural surfaces that will directly contact food
Cannot directly contact the reflective coating of the mirror
CONSTRUCTION
1. Cleaning of substrate surface
(1) The purpose of surface treatment before bonding is to remove oil, dust, surface damage and loose natural oxide film on the surface of the base material during the production and transportation process, so as to roughen the surface of the base material and form a surface suitable for mechanism embedding. morphology, while improving surface chemical properties and improving durability under the influence of stress environmental factors.
(2) Cleaning solvents are usually isopropyl alcohol, methyl ethyl ketone, and xylene. The cleaning cloth should be white, clean, soft, non-linting cotton.
(3) Use the "double cloth wiping" method to clean the surface of the substrate. Soak a clean cloth with solvent. Wipe the surface of the substrate in only one direction. Before the solvent evaporates, immediately use a second cloth with a clean dry surface. Wipe the solvent off the surface of the substrate.
(4) Do not put the soaking rag into the container for soaking, otherwise the clean solvent will be contaminated and the cleaning effect will be affected.
(5) Only clean the bonding and sealing construction part within 1 hour each time. Do not expose the cleaned substrate surface to the air for too long.
2. Make a bet
Use plastic tape to cover the surface near the interface to ensure that the sealing working lines are perfectly neat.
Cut the mouth of the hose, install the pointed tube, and then cut it at a 45° angle according to the size of the gap.
Install the sealant gun and press out the sealant along the gap at a 45° angle to ensure that the sealant is in close contact with the surface of the base material. When the joint width is greater than 15 mm, sealant needs to be applied multiple times. After gluing, trim the surface with a knife to remove excess sealant, then tear off the tape. If there are stains, use a damp cloth to remove them.
3. Pad material
Open-cell polyurethane or closed-cell polyethylene foam padding rods and polyethylene materials are recommended lining materials. Prevent sealant from sticking on three sides.
STORAGE & SHELF LIFE
Store the original sealant in a dry place, the temperature should not be higher than 27 degrees, the storage period is 12 months from the date of production.
