Silicone rubber waterproof mastic sealant is a non-shaped sealing material composed of organopolysiloxane as the main agent, with vulcanizing agent, vulcanization accelerator, reinforcing filler and pigment added. According to the use, it can be divided into F type and G type. Type F is used for building joints while Type G is used for mounting glass. According to the fluidity, it can be divided into N type and L type. The N type is non-sagging type while the L type is self-leveling type. According to different vulcanizing agents, silicone rubber sealants can be divided into acetic acid type, ketone oxime type, alcohol type, amine type and amide type. In general, high modulus silicone rubber building sealant uses two types of vulcanization systems: acetic acid type and alcohol type; medium modulus silicone rubber building sealant adopts alcohol type vulcanization system; low modulus silicone rubber construction sealant adopts amide type vulcanization system.

The waterproof principle of silicone rubber foam sealing strip: silicone rubber sealing strip will elastically deform under pressure, so that the gap between the contact interface and the sealing strip is filled and generates a rebounding force, so that the contact surface and the foam sealing strip produce friction. When the sealing strip itself does not leak and when the friction force and the rebounding force are greater than the internal pressure or the external pressure of the sealed medium, the sealing material does not leak due to deformation or displacement, and vice versa.

How To Use Quick-drying Sealant 

1.Use: A single group of silicone glass glue can be used immediately. It is easy to type it from the bottle with a glue gun, and a spatula or wood chip can be used to trim the surface.

2.Adhesion time: the curing process of silicone rubber is developed from the surface to the inside. The silicone glue drying time and curing time of different characteristics of silica gel are different. So if you want to fix the surface you have to do it before the glass gel sheet is dry (acid glue, neutral and transparent glue should be in 5-10 minutes, neutral color glue should be in 30 minutes generally). If the color paper is used to cover a certain place, after coating, it must be removed before the skin is formed.

3.Curing time: the curing time of glass glue increases as the adhesive thickness increases. For example, the acid glass glue of 12mm thickness may take 3-4 days to solidify. But within about 24 hours, the outer layer of 3mm has been solidified. When glued to glass, metal or most wood, the fast drying silicone adhesive has an anti-stripping strength of 20 pounds per inch at room temperature after 72 hours. If the use of glass glue is partially or completely sealed, the solidification time is determined by the closeness of the seal. In a place of absolute closeness, it is possible to remain uncured forever. If the temperature is raised, the glass will soften. The gap between metal and metal bonding should not exceed 25mm. In all kinds of bonding situations, including airtight conditions, the adhesion effect should be thoroughly checked before the equipment is used. In the curing process, acid glass glue will produce a smell due to the volatilization of acetic acid, which will disappear in the curing process. There will be no smell after curing.

4.Adhesion: A. Wipe the surface of the metal and plastic completely, remove the oil, and then wash the whole surface with acetone except for the plastic. If it is rubber surface, apply sandpaper and rub it with acetone. Please observe the precautions when using acetone. B. Apply the glass glue evenly on the surface of the prepared object. If the two surfaces are glued together, place one side properly first and press the other side to squeeze out the air, but be careful not to extrude the glass. C. place the bonding device at room temperature and wait for the glass to solidify.

5.Seal: the silicone glass sealant also can be used for sealing purposes according to the above steps. Squeeze the glass glue into the joint or the seam so that the glass glue is in full contact with the surface.

6.Cleaning: before curing, the glass glue can be erased with a cloth or paper towel. After curing, it should be cleaned with a scraper or xylene, acetone and other solvents.

RTV-1 silicone is a condensed silicone rubber that is gradually cured from outside to inside by contacting with moisture in the air. It can be also called non conductive silicone sealant. RTV-1 silicone rubber are used in bonding, sealing, encapsulating photovoltaic module components including photovoltaic frame, junction box and micro-inverter, power industry including circuit boards, electronic components, light emitting diode industry including lamp beads, lamp cap and light bar, home appliance including air conditioner, fridge, washing machine, and microwave oven, induction cooker, new energy vehicle including electronic component. GOLOHO RTV-1 silicone rubbers are designed to provide long-term bonding, sealing, encapsulating and protection against moisture, environmental degradation, mechanical and thermal shock, heat dissipation and vibration where a room-temperature-curing product is preferred.

When using RTV-1 silicone rubber, all surfaces must be clean and dry. Degrease and wash off any contaminants that could impair adhesion. Suitable solvents include isopropyl alcohol, acetone, or methyl ethyl ketone. Apply a bead of RTV-1 silicone rubber to one of the prepared surfaces, then quickly cover with the other substrate to be bonded. On exposure to moisture, the freshly applied material will “skin over” in about 10 to 15 minutes at room temperature and 50% relative humidity. Any tooling should be completed before this skin forms. The surface is easily tooled with spatula. GOLOHO RTV-1 silicone rubbers will be tack free in about 5 to 60 minutes. After skin formation, cure continues inward from the surface. In 24 hours (at room temperature and 50% relative humidity), GOLOHO RTV-1 silicone rubbers will cure to a depth of 2 to 3 mm. Very deep sections, especially when access to atmospheric moisture is restricted, will take longer to cure completely. Cure time is also extended at lower humidity levels. Before handing and packaging bonded components, users are advised to wait a sufficiently long time to ensure that the integrity of the adhesive seal is not affected. This will depend on many factors and should be determined by user for each specific application.
