YT-921 Neutral Silicone Sealant for Granite and Concrete
1.Description:
YT921 is a universal construction silicone sealant developed by our company,it overcomes the disadvantages of acetoxy cure silicone sealant such as unpleasant odor,corrosion to metal and coated glass.YT921 can substitutes acetoxy cure silicone sealant for sealing joints and has more widely application.
2.Characteristics:
. YT921 belongs to RTV-1 good extrusion,Aluminum plate on and thixotropy between 4℃~40℃.easy to use;
. Neutral curing,non-corrosive to coated glass,concrete,marble,granite etc;
. Release low-molecular-weight alcohol and no unpleasant odor during cure;
.
Excellent resistance to low and high temperature change.No
fragility,rigidfication or crack at-50℃ and no softening, degradation at
150℃ whencured.it always keeps good elasticity;
. Excellent adhesion to most common building material without priming;
. Good compatibility with other neutral silicone sealants.
3.Purpose:
. Glazing for all type door and window;
. Sealing for metal structural engineering joints;
. Many other uses.

5.Application Standard:
YT921 is meet the following standards, or above.
. National standard GB/T14683-2003
. Company standard Q/(NGS) YT 1-2005
. U.S.A ASTM C 1184-2013
. ISO9001:2008
6.Package:
. YT921 in 310ml Cartridge net 300ml.or in 590ml multi-membrane cartridge.
7.Restriction of Usage:
. Cannot be used as structural sealant;
. Unsuitable for all kinds of material that can effuse grease, plasticizer or solvent;
. Unsuitable for the airproof location, because it is required to absorb moisture in air to cure for the sealant;
. Unsuitable for the frosty or moist surface;
. Unsuitable for the continually soggy or moist place;
. Cannot be used the product if the temperature is below 4℃ or above 40℃ on the surface of the materials.
8.Technical Service:
. Offer the integral technical data of the products.
. Adhesion Test:
The
products of Yt921 silicone sealant have excellent adhesion to most
common building material, such as glass,anodized aluminum,ceramic
tile,granite,brick, wood,steel and most plastics.But we cannot ensure
our sealants are suitable to all materials,as a result of the unceasing
appearance of new building materials and the application of new surface
treatment technology.In some cases,it is required to have the adhesion
test on the substrates.In the laboratory of our company,we can carry out
the adhesion test for clients and give the test report that includes
experimental result,recommended products,cleaning methods of the
material surface etc.
. Compatibility Test:
Ifthe accessory
materials like baker,double-sided glue strip can not be compatible with
silicone rubber,it may cause silicone rubber to turn colors, even lose
adhesion.To avoid these problems, we provide services of compatibility
test for clients.Clients can send the accessory to us by mail (or other
ways), then we will carry out the compatibility test and give the test
report.
. Staining Test:
We provide services of pollution test for
clients.Clients can send the substrates to us by mail(or other
ways),then we will carry out the staining test and give the test report.
9.Joint Design and Working Procedure:
See also "The Technology Instruction of YuanTong Construction Silicone Sealant".
10.Safety:
. Non-toxicity when cured;
.
Avoid eye contact before curing.If happened, rinse opened eye for
several minutes under running water,then consult with a doctor;
. Keep away from children;
. Ensure adequate ventilation at workplace or curing area.
11.Estimation of Dosage:
Remark:The
actual dosage of silicone sealant may be different from interface
design,installation place of gasket material,dressing technology and
amount of wastage on site.
Please refer to Table 1 for the estimated
dosage of Yt921 special point-support curtain wall sealant needed by
various specification interfaces.
