Silicone glass glue is a kind of silicone products. Silicone glass glue is divided into two types, one-component and two-component, mainly used for insulating glass sealing. Two-component silicone glass sealant is a room-temperature vulcanized two-component sealant with room temperature vulcanization silicone rubber 107 and methyl silicone oil 201 as the main agent and metal oxide as the vulcanizing agent. Weather resistance and UV resistance, high and low temperature resistance and aging resistance; high bonding strength; good adhesion to glass and aluminum alloys. Mainly used for insulating glass to seal the second seal. Next, the sealant manufacturer will introduce you to the use of silicone glass glue! Let's learn together!
use
The one-component silicone glass glue is ready to use, easily ejected from the bottle with a glue gun, and can be trimmed with a spatula or wood chip.
Sticking time:
The curing process of silicone rubber develops from the surface inward, and the surface drying time and curing time of silicone rubber with different characteristics are different (for the detailed description of curing time, please refer to the "Technical Parameters" content in Chapter 4), so if you want to Repairing the surface must be carried out before the surface of the glass glue is dry (acid glue, neutral transparent glue should generally be within 5-10 minutes, neutral variegated glue should generally be within 30 minutes). If separation paper is used to cover an area, after applying the glue, be sure to remove it before the skin is formed.
Curing time:
The curing time of glass glue increases with the increase of bonding thickness. For example, acid glass glue with a thickness of 12mm may take 3-4 days to solidify, but within about 24 hours, the outer layer of 3mm has been cured. 20 psi peel strength after 72 hours at room temperature when bonding glass, metal or most woods. If the place where the glass glue is used is partially or completely closed, then the curing time is determined by the tightness of the sealing. In an absolutely airtight place, it is possible to remain uncured forever. Increasing the temperature will soften the glass glue. The gap between metal-to-metal bonding surfaces should not exceed 25mm. In various bonding occasions, including airtight conditions, the bonding effect should be fully checked before the bonded equipment is used. During the curing process of acid glass glue, there will be a smell due to the volatilization of acetic acid. This smell will disappear during the curing process, and there will be no peculiar smell after curing.
Bonding:
A. Wipe metal and plastic surfaces completely to remove oil stains, then use acetone to rinse all surfaces except plastic, and sand the rubber surface, then rub with acetone. When using acetone, observe the precautions for using this solvent.
B. Apply the glass glue evenly on the surface of the prepared object. If you want to bond the two surfaces, you can find a place for one side first, and then squeeze the other side with enough force to squeeze out the air, but be careful not to squeeze it. out the glass glue.
C. Place the bonded device at room temperature and wait for the glass glue to cure.
Seal:
When silicone glass glue is used for sealing, also follow the above steps to squeeze the glass glue into the joint surface or gap, so that the glass glue can fully contact the surface.
clean:
Before the glass glue is cured, it can be wiped off with a cloth or paper towel. After curing, it must be scraped off with a scraper or scrubbed with solvents such as xylene and acetone.
Precautions:
During the curing process, acid glass glue will release irritating gas, which is irritating to human eyes and respiratory tract. Alcohol-based neutral adhesives release methanol during curing. Methanol has a potential carcinogenic hazard and is a known skin and respiratory irritant. The volatile gas can cause irritation of the eyes, nose, and throat. Therefore, it should be used in a well-ventilated environment, avoid entering the eyes or contacting the skin for a long time (after use, wash hands before eating and smoking), and do not swallow this product. Keep out of the reach of children; the construction site should be well ventilated; if accidentally splashed into the eyes, flush with clean water and seek medical attention immediately. Fully cured glass glue is not dangerous.
General Guidelines:
Before use, please read carefully the correct construction method and use of glass glue, please pay attention to the instructions on safe use and health hazards.
