Hydroxy Terminated Polydimethylsiloxane applies to RTV silicone rubber sealant potting

1. Product features

ZS-NJ-D939C is one kind of the one-component dealcoholized silicone sealant which is Room temperature curing. This products have the properties such as high strength, good adhesion on Aluminum, copper, Stainless steel and other metal, excellent dielectric and good heat resistance. The general use of temperature range is from -60℃~200℃. During the curing process, it will release the alcohols, which with no corrosion to the materials such as polycarbonate(PC) and copper. Absolutely compliance with the EU ROHS’s requisition.

2. The typical use

1,The bulb housing adhesive fixed and general light jewelry adhesive seal.

2,Adhesive fixed potting of smart prepayment water meter,Adhesive sealing of general lighting products and electronic components.

4. Instructions

1. Surface cleaning:cleaning coated surface,remove the rust,dirt and oil.

2. Brush the glue: Unscrew the hose cap (or cut open), pushed the glue to the clean surface, evenly distributed so that will be glued surfaces together and fixed.

3.Curing: put the glued or sealed parts in the air and let it be natural cured. It’s one curing process that cured from the surface to the internal, in less than 24 hours (at room temperature and 55% relative humidity) glue curing depth of 2 ~ 4mm, if the sizing location more deeper, in particular, which is not easily accessible to the air, then the fully curing time will be extended, if the temperature is low, the curing time will be extended too, sealant is fully cured at least 7 days if the thickness of 6mm.


after Operating, unused glue must be sealed and stored , and tighten the cap immediately,. if the seal has a little crust when use it in the next time, remove it and it will not affect the normal use. During the storage process, the canal orifices may appear a small amount of the curing phenomenon, cleared it and it can use it again, and no influence to the product performance.

6. Packaging specifications

Sample: 100mL / tube, 100tubes / box; 300mL / tube, 25tubes / box.

7. Storage and transportation
