In many industries now, sealant is widely used. For example, the doors and Windows industry that I work in, sealant is used more frequently, and for example, in decoration, the same sealant will be used. Two types of sealant, 995 structural adhesive and glass adhesive are used. For the wide, these two kinds of glue belong to the sealant, what is the difference?

1: The difference in packaging

There are two kinds of packaging of glass glue, one is plastic drum packaging, will be printed with the word glass glue. The other kind of packaging is soft bags filled in long bucket plastic bag type, with the word silicone sealant printed on the packaging.

The packaging of structural adhesive and silicone sealant is the same, but also soft package, the packaging will generally be printed with silicone structural sealant or silicone weather resistant structural sealant, and the difference between glass glue is the word "structure".

2: The difference between glass glue and structural glue performance

Glass glue is mostly used for pasting and sealing, oxidation resistance and weather resistance, temperature resistance, bearing performance is low, so it is mostly used for sealing the gap between indoor objects. For example, the seal of the gap of indoor doors and Windows, the seal of the table, the seal of the gap of the corner, the seal of the ceramic tile between the toilet and the ground, and the paste and seal between the glass. In a word, glass glue can be used to fill gaps in the room.

Structural adhesive has the characteristics of sticking force, flexibility, bearing power, oxidation resistance, structural stability, etc., it is used for pasting between different materials. For example, paste between curtain wall glass and window frame, paste between stone and wall, paste between door frame and wall.

Weather resistant structural sealant is generally used with structural structure, structural adhesive is responsible for material paste, the weather resistant structural sealant is responsible for filling the surface gap. For example, the gap between the glass curtain wall is sealed, the surface of the gap between the steel hanging stone is sealed, and the seal between the outer wall window frame and the wall is sealed. In short, weather resistant structural sealant is used for pasting and sealing between outdoor materials.

What do the numbers on the sealant mean

On the surface of any sealant package, there will be some Arabic numerals printed. For example, the same kind of silicone weatherproof sealing offset printing has 225, 995, 2000, 6000 words, these words represent the sealant paste hardness and strength, the more back, on behalf of the sealant hardness and strength is higher, better weather resistance, longer service life.

Summary: The difference between structural glue and glass glue, it can be believed that glass glue is only suitable for sealing gaps, can not be used for structural paste between materials, mostly used indoors. Structural adhesive is used for structural paste and seal between the same or different materials. It is mostly used outdoors. Structural adhesive is much more expensive than glass adhesive in price.

In addition, in the choice of sealant, Uman 995 structural glue manufacturers suggest to buy brand products as far as possible, some small factory production of sealant in quality is still very worrying.
