Silicone Sealant

Silicone sealant is a part of silicone products. It is mainly divided into deacetic acid type, dealcoholic type, deamination type and oxime type. Silicone sealant is also known as glass glue because users buy silicone sealant is mainly used in glass bonding and sealing. The chemical composition of polydimethylsiloxane, silica polymer can all be called silicone. Silicone sealant is a kind of ointment or gel. Once it comes into contact with the moisture in the air, it will solidify into a tough rubber like solid material.

Zhongtian Silicone Sealant Product Series

Silicone sealant product series is a significant part of the whole products series of Zhongtian. It is likely that you have used silicone sealant on your own, or seeing others use is or merely walked by it. Because of the strong adhesive bonds that silicon is able to generate, silicon sealant enjoys quite wide application in various fields. Find silicone window & door sealant as well as a weather-resistant adhesive for neutral curtainwall here in Zhongtian! As silicone sealant suppliers, we provide customers with a reasonable silicone sealant price.

Silicone Window & Door Sealant

One component, neutral, room temperature curing building silicone sealant, and non-corrosive for most of building materials.

Weather-resistant Adhesive For Neutral Curtainwall

GS885 is one component, neutral cure siliconesealant. It curing quickly, high adhesive strength and high modulus.

Silicone Sealant Properties

Silicone sealant is an adhesive in liquid form. Silicone sealant must be cured under temperature between 40°F to 100°F and humidity between 5% and 95%.Generally speaking, the outlook, touch feeling and function of silicone based caulksealant are much like a gel. It has the following properties:

Flexibility: Silicone can keep its elasticity and stability is not only high but low temperatures when compared to other adhesives. The silicone based sealant is highly flexible and can accommodate movement and expansion of materials without cracking or losing its adhesion.

Chemical resistance: Silicone based sealant is resistant to many chemicals, solvents, and oils, making it suitable for sealing in environments where exposure to these substances is likely. The chemical resistant silicone sealant can withstand exposure to acids, alkalis, and other corrosive materials without deteriorating or losing its adhesion.

Water resistance: Silicone based sealant is waterproof and can effectively seal out water and moisture. It forms a durable barrier that prevents water from penetrating through the seal, making it ideal for sealing bathroom fixtures, kitchen sinks, and other areas that are exposed to water.

Silicone Sealant Uses

Compared with other adhesives, silicone sealant has great use-value and strong applicability. It can bond with many materials and show strong tensile properties. During the work, even under great tension and pressure, it will not easily encounter deform. Good resistance to stretching and tearing, play a super protective role. As one of the local China silicone sealant manufacturersand silicone sealant suppliers, Zhongtian can provide you high-quality silicone sealant application solutions, which can be widely used in new energy, military, medical, aviation, shipping, electronics, automobile, instrument, power supply, high-speed rail, and other industries.

How To Apply Silicone Sealant?

Silicon is often used to finish joints, prevent humidity and fill seams or gaps. You need to apply silicon sealant step by step.

First of all, choose the proper type of silicon sealant. It needs to be noted that not all types of silicone sealants can be painted over. Bonding before you paint over the sealant. Choose the color that is most suitable for the underlying surface. Then the oxidation step takes place. It is worth mentioning that if the silicone sealant used contains any acidic elements, this step will be taken on the underlying surface. And then you need to clean the surface, remove any glue or residues before masking. Using the sealant cartridge then by employing a hobby knife. The next will be making the seal, in which the ideal working position will be holding the sealant gun at an angle of 45°. Last but not least, finishing off the sealant line by wetting your finger with some soapy water. Here you have finished the whole process of applying the silicone sealant.

Using Limited Conditions of Silicone Sealant

Various silicone glass sealant is subject to the following restrictions when used.

-Not suitable for construction in places with long-term water immersion.

-not with the material soluble with oozing grease, plasticizers or solvents.

-frost or wet surface can not be bonded.

-completely closed place can not be cured (silica gel needs to be cured by the moisture in the air).

-the substrate surface is not clean or not firm when not bonded.

Acid silicone glass sealant will corrode or can not bond copper, brass (and other copper alloys), magnesium, zinc, electroplated metal (and other zinc alloys), while it is recommended that masonry materials made of goods and carbonized iron substrate do not use acidic glass adhesive in methyl isobutyrate (PLEXIGLAS), polycarbonate, polypropylene, polyethylene and TEFLON (Teflon, polytetrafluoroethylene) made of The use of this product on the material will not be able to obtain a good bonding effect and good compatibility.

It is also not suitable for joints moving more than 25% of the joint width, and it is better not to use ordinary acidic glass adhesives on structural glass (except acidic structural adhesives), and acidic glass adhesives should not be used in places where abrasion and substantial disadvantages can occur. Silicone acid glue substrate surface temperature of more than 40 ℃ is not suitable for construction.

Types of Silicone Sealant

By product packaging

Single-component and two-component.

Single-component silicone adhesive, the curing of which is dependent on contact with moisture in the air to produce a change in physical properties.

Two-component means that the silicone adhesive is divided into two groups A and B. Any group alone cannot form a cure, but once the two groups are mixed, they produce a cure.

The common market is a single-component silicone glass adhesive.

By nature

Single-component silicone glass adhesive is divided into two types of acidic and neutral adhesives by nature.

Acidic glass adhesives are mainly used for general bonding between glass and other building materials. The neutral glue overcomes the characteristics of acidic glue corroding metal materials and reacting with alkaline materials, so it has a wider range of application, and its market price is slightly higher than acidic glue.

A special type of glass adhesive in the market is silicone structural sealant, which is directly used for metal and glass structure of glass curtain wall or non-structural bonding assembly, so the quality requirements and product grade is the highest in glass adhesive, and its market price is also the highest.

By color

Silicone glass adhesive has a variety of colors, commonly used colors are black, porcelain white, transparent, silver gray, gray, bronze six kinds. Other colors can be customized according to customer requirements.
