How to use glass silicone sealant for home decoration?

When people are decorating their new homes, they may encounter the need to use glass silicone sealants. The scope of use of glass silicone sealants is actually relatively wide, so it is best for everyone to know about glass silicone sealants. For the knowledge of ketone sealant, many friends are more willing to go to the large glass silicone sealant by themselves, but if your memory is not proficient, you will find that there are bubbles or unevenness in the glass silicone sealant, you need to To improve our own skills, today we will talk about some methods and steps of glass silicone sealant.

1. The quality of glass silicone sealant can be inspected from the aspects of viscosity, tension, whether it is mildew-proof, whether it is easy to clean, whether it will change color, etc. From the color point of view, glass silicone sealant has various colors, white, black, color And so on, and transparent colors.

2. Acidic silicone glass silicone sealant: It has a wide range of bonding and has excellent adhesion to most building materials such as glass, aluminum, and oil-free wood. But it cannot be used for bonding ceramics, marble, etc.

3. Neutral silicone glass silicone sealant: can be used to bond ceramic sanitary ware, marble, etc.

4. There are many varieties of glass silicone sealant on the market, including acid glass silicone sealant, neutral weather-resistant glue, silicic acid neutral structural glue, silicone stone glue, neutral anti-mildew glue, hollow glass silicone sealant , special sealant for aluminum-plastic panels, special glue for aquariums, special glue for large glass, special glue for bathroom anti-mildew, acid structural glue, etc.

How to use glass silicone sealant?

1. Use: One-component silicone glass silicone sealant can be used immediately. It is easy to punch it out of the glue bottle with a glue gun, and the surface can be trimmed with a spatula or wood chips.

2. Adhesion time: The curing process of silicone adhesive develops from the surface to the inside. The surface drying time and curing time of different characteristics of silica gel are different, so if the surface is to be repaired, it must be on the surface of the glass silicone sealant. Before drying (acid glue, neutral transparent glue should generally be within 5-10 minutes, and neutral variegated glue should generally be within 30 minutes). If color separation paper is used to cover a certain place, after the glue is applied, it must be removed before the skin is formed.

3. Curing time: The curing time of glass silicone sealant increases with the increase of bonding thickness. For example, the acid glass silicone sealant with a thickness of 12mm may take 3-4 days to solidify, but within about 24 hours, Already 3mm of the outer layer has cured. When bonded to glass, metal or most woods, it has a peel strength of 20 psi after 72 hours at room temperature. If the place where the glass silicone sealant is used is partially or completely closed, then the curing time is determined by the tightness of the seal. In an absolutely airtight place, it is possible to remain uncured forever. Increasing the temperature will soften the glass silicone sealant. The gap between metal and metal bonding surface 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, the acid glass silicone sealant will produce a smell due to the volatilization of acetic acid, which will disappear during the curing process, and there will be no peculiar smell after curing.

4. Bonding: A. Clean the metal and plastic surfaces completely, remove oil stains, and then rinse the entire surface with acetone except the plastic, and polish the rubber surface with sandpaper, and then wipe it with acetone. When using acetone, observe the precautions for using this solvent. B. Apply the glass silicone sealant evenly on the surface of the prepared object. If the two surfaces are bonded together, 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 out the glass silicone sealant. C. Place the bonded device at room temperature until the glass silicone sealant is cured.

5. Sealing: When the silicone glass silicone sealant is used for sealing, also follow the above steps, squeeze the glass silicone sealant into the joint surface or gap, so that the glass silicone sealant and the surface Full contact.

6. Cleaning: Before the glass silicone sealant 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 xylene, acetone and other solvents.
