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 based caulk 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 manufacturers, 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 silicone sealant. It curing quickly, high
adhesive strength and high modulus.

Silicone Sealant Properties
Silicone sealant is an adhesive in liquid form. Generally speaking, the
outlook, touch feeling and function of silicone sealant are much like a gel. It
has the following properties:
1. Silicone can keep its elasticity and stability is not only high but low
temperatures when compared to other adhesives.
2. Silicone is other chemicals, moisture, and weathering resistance.
3. Silicone sealant must be cured under temperature between 40°F to 100°F and
humidity between 5% and 95%.

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
manufacturers, 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.

Categories 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.
