Small white customer, how to distinguish the quality of glass glue (silicone sealant)? Can only be pit? Take a look at the introduction of Oman environmental protection small series!

.. Look at the packing.

Clear printing, neat font, factory name, factory address, product name, date and other relevant information accurate and detailed. Make sure the product is used for the same purpose as you (some special use products are not marked, you can check with your supplier), and then look at the "shelf life". The better the glass glue, the longer the storage period should be in the relative environment, basically the higher the use of environmental requirements, the better the quality of glass glue, of course, the longer the storage period.

Second: look at the bottom of the rubber cylinder.

It is normal to see whether there is glass glue overflow at the edge of the stopper. Because there is no air left inside the glass glue encapsulation, the piston must be pushed up with force in order to squeeze out the air inside, and the glue overflow is seen. Therefore, there are also people in the industry to get the barrel glass glue with the top glue plug, the top does not move is normal, if the top moved up, the quality of this glue is doubtful.

Third: look at the production date.

Expired glass glue will greatly reduce the quality of the glue

Fourth: drawing.

The longer the wire drawing, the higher the viscosity of the glass glue, the higher the viscosity, the better the quality

No. 5: Smell.

The lighter the taste of neutral glass glue during curing, the better the quality, and no taste after curing.

Sixth: look at the displacement size.

Good glass glue on the vertical surface, not cured will not appear displacement or collapse phenomenon

Seventh: curing speed.

After playing out to see the curing speed, good glass glue under normal circumstances can be about ** curing depth of 7mm. Too long time may not be good or the glue is not authentic. Too fast that is the curing agent added more, curing agent added too much after easy to harden, elasticity is not good so that the life is not long. So the market of the same grade of glass glue, quick - drying type are relatively cheap

See the above introduction, do you understand? Oman reminds: small white customers, in the purchase of glass glue, be sure to polish your eyes, to prevent being cheated!
