∎Packing Specification
●Cartridge 310ml
●Sausage 400ml
●Sausage 600ml
●Pail/Drum 240kg
310ml: 24pcs per box , 600ml:20pcs per box
∎Direction for use
Tool: Manual or pneumatic plunger caulking gun
●Cleaning: Clean and dry all surfaces by removing foreign matter and contaminants such as oil dust, grease, frost, water, dirt, old sealants and any protective coating.
●For cartridge
1.Cut nozzle to give the required angle and bead size
2.Pierce the membrane at the top of the cartridge and screw on the nozzle
3.Place the cartridge in an applicator gun and squeeze the trigger with equal strength
●For sausage
1.Clip the end of the sausage and place in barrel gun
2.Screw end cap and nozzle on to barrel gun
3.Using the trigger extrude the sealant with equal strength
∎Attention of operation
● Choose this product, primer, activator and other matching product, must have bonding test before bonding the materials, to ensure that they have good compatibility. At the same time, before application, should guarantee that the sealant, primer and activator are in the warranty period.
●Please strictly according to the application process, any violation of the application operation may cause bonding failure. This product is innocuous after curing completely, but before
curing, please avoids contacting with eyes and skin. In case of eyes and skin contact, wash immediately and thoroughly with soap and water. If the situation is serious, please go to see a doctor immediately
∎ Instruction
Surface preparation
Surface must be clean, dry, free of water, oil, grease or rust and of sound quality. Remove all loose particles or residues with a jet of compressed air, sandpaper, hard brush. Clean surface with a solvent, like acetone, if the substrate can stand it.
Priming
Pre-test substrates for adhesion. Cleaners and/or primers may be required to achieve optimal adhesion. As a rule, substrates must be prepared in accordance with Adeseal instructions; specific guidance regarding adhesion on specific surfaces may be obtained by submitting substrate samples
for analysis to our Laboratories.
Tooling and finishing
Tooling and finishing must be carried out within the tack-free time of the sealant.
Removal
Uncured product can be removed with a white spirit or another suitable solvent. Once cured, the
material can only be removed mechanically.
Over-painting
In general, it can be over-painted. The paint must be tested for compatibility by carrying out preliminary tests. Attention must be observed with the use of alcohol or alkyd-resin since they may interfere with the curing process of the sealant and modify the drying time of the paint itself. It should be understood that the hardness and rigidity of the paint film may impair the elasticity of the sealant and lead to cracking of the paint film.
Application
Pierce through the protective membrane in the front threaded section. Screw on the plastic nozzle and cut it at an angle according to the desired bead
thickness & profile. Fit the cartridge into a manual or pneumatic air operated gun (provided with telescopic piston) and apply material carefully preventing air entrapment. Once opened, packs should be used up within a relatively short time.
Do not apply at temperatures below 5°C or above 40°C. The optimum operating temperature for
both substrate and sealant is between 15°C and 25°C.
Limitations
●PU-24 may be painted.However some coatings may crack if movement occurs, preliminary tests recommended.
●Avoid exposure to high levels of chlorine (avoid to seal joints in chlorinated swimming pools).
● Do not cure in the presence of curing silicone sealants.
● Avoid contact with alcohol and other solvent cleaners during cure.
●Do not apply when moisture-vapour-transmission condition exists from the substrate as this can cause bubbling within the sealant.
●When applying sealant, avoid air-entrapment.
● Since system is moisture-cured, permit sufficient exposure to air.
● White colour tends to yellow slightly when exposed to ultraviolet rays.
●The ultimate performance of Pu Construction depends on good joint design and proper application with joint surfaces properly prepared.
●PU construction should not be used for structural glazing
∎Transport &Storage
● Transport: Keep the sealed product away from moisture, the sun, high temperature and avoid collisions.
● Storage: Keep the sealed product into cool, dry place.
● Storage temperature: 5~25℃. Humidity: ≤50%RH.
●Cartridge and Sausage :9 month. Pail/Drum:6 month.
Notice:If the temperature is higher than 40 ℃ or the humidity is more than 80%RH, the shelf life may be shorter.
