4．Packing
- Plastic bottle packing, net volume is 310ml;
- Sausage Packing, net volume is 400ml;
- 5 gallons drum packing, net weight is 25kg;
- 55 gallons drum packing, net weight is 235kg or 270kg.
5．Pretreatment procedure of adhesive surface
- All the surfaces must keep clean and dry, clean out the grease and
contamination that have bad effect on adhesive surface. The solvent
applicable include propel alcohol, or methyl ethyl ketone.
- Adhesion with some certain kind of plastics need to use special
surface treatment. For example, adhesion with polypropylene and
polytetrafluoroethylene need chemical corrosion or
plasma-treatment, therefore it can reach optimal adhesion.
6．Instructions
- Apply SMG533 neutral sealant on the pretreated surface, cover the
another cover instantly.
- When exposed to moisture at room temperature and 50% relative
moisture, the surface of sealant would cure in crust in 10 to 15
minutes. Before curing the residual sealant should be swept out by
knife tool ( use blade will sweep out the cure skin easily).
7．Curing Time
After formation of crust, curing process will penetrate into inside
sequentially. In 24 hours time (at room temperature and 50%
relative moisture), curing thickness of SMG533 neutral sealant is
4.1mm. The deep-seated part, especially the part that has limit
contact with air has longer curing time. Similarly curing time
would extend in low-temperature condition. We advise the users wait
patiently (enough time) to avoid affecting the integrity of the
sealant. This time is depended by many factors, it should decided
by users (decide through special application of the sealant).
8．Service life and storage
When SMG533 neutral sealant is original biding , kept in shade and
dry at the temperature below 27℃, useful life of neutral sealant is
9 months (since product time).
As the result of SMG533 neutral sealant would react with moisture
of the air(form curing skin),the sealant must be tightly sealed in
containers when not used. Blockage can form in sealant tube or tube
end in storage time, it can be clean out easily ,residual component
of the sealant won’t change.
9. Precautions
This product is innocuous after curing, but avoid contacting with
eyes and children before curing; The work area must keep
ventilation state.
