Packaging and Storage

1. This GDZ421 room temperature vulcanizing silicon rubber sealant  is packaged and sealed in metal hose, sealed and stored, and transported as non-dangerous goods.
2. Package specification: 100g / piece, 10 pieces in a box.
3. Keep dry during storage and transportation to prevent sun and rain. The storage period of this product is half a year. The expired products can still be used after re inspection.


Since the basic polymer, filler and crosslinking agent of one component RTV silicone rubber Sealant GDZ series have been evenly mixed and packaged in one container; the rubber can be vulcanized into elastomer only by extruding the rubber and contacting the moisture in the air. It can also be dispersed in a suitable solvent for spraying, dipping or brushing. When preparing the dispersion, use dry solvent and avoid contact with moisture in the air.
