8.Technical Service:
Offer the integral technical data of the products.
-Adhesion test:
The products of YT928 silicone sealant have excellent adhesion to most common building material,as glass, anodized aluminium, ceramictile, 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:
If the 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 submit the test report.
9.Joint Design:
The joint design of silicone structural sealant must be carried out according to JGJ102 "The Technical Order of Glass Curtain Wall Engineering" by professional designers;
The width and thickness of silicone structural sealant are no less than 6mm;
The width of silicone structural sealant should be greater than or equal the thickness;
The joint of silicone structural sealant can be full of the sealant according to common working procedure;
The adhesive width and thickness design of silicone structrual sealant must be carried out according to JGJ102 "The Technical Order of Glass Curtain Wall Engineering";
The sealant should be able to exposure in the air. Cannot move the joint during the cure.
10.Working procedure:

11.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.
12.Cure Time:
YT9288 begins cure from surface to deep after exposure in the air. The Tack-Free Time is about 60min, and the entire curing takes place after 21 days.
