Sika SG20S structural sealant
Sikasil ® SG-20S is a one-component neutral curing organic silicon adhesive for structural glass, which can effectively adhere to a variety of substrates
Comply with GB 16776-2005, ASTM C 1184&ASTM C920 for Type S, Grade NS, Grade 25 (displacement capacity ± 25%)
Very good UV resistance and weather resistance can be effectively adhered to many substrates, including glass, metal, coated metal, plastic and wood
Sikasil ® SG-20S is used for structural glass and other adhesive construction.
This product is only applicable to experienced professional users. The actual substrate and conditions must be tested to ensure adhesion and material compatibility.
Sikasil ® SG-20 S reacts with moisture in the atmosphere to solidify. At low temperature, the moisture in the air is usually low, and the curing reaction rate is slightly slow (see Figure 1)
The surface shall be clean, dry and free of grease, oil and dust.
The surface treatment depends on the specific properties of the substrate and will affect the adhesion durability.
The optimum temperature of base material and sealant is between 15 ° C and 25 ° C.
Sikasil ® SG-20 can be processed with manual, pneumatic or electric glue gun and pump equipment. For suggestions on selecting and setting up the appropriate pump system, please contact Sika Industrial Systems Engineering.
The joint must be of proper size.
The calculation of necessary joint size is based on the technical data of adhesive and adjacent building materials, the exposure degree of building components, their structure and size, and external loads.
The joint depth shall not exceed 15 mm
The finishing and completion must be carried out within the molding time of the sealant or adhesive.
Modified Sikasil ® For SG-20S adhesive surface, in order to achieve better wetting effect, the adhesive can be extruded without using mold agent.
Packaging method 600ml sausage package
1.What is the minimum order quantity for your rubber products?
We didn’t set the minimum order quantity,1~10pcs some client has ordered
2.lf we can get sample of rubber product from you?
Of course, you can. Feel free to contact me about it if you need it.
3. Do we need to charge for customizing our own products?And if it is necessary to make tooling?
if we have the same or similar rubber part, at the same time, you satisfy it.
Nell, you don’t need to open tooling.
New rubber part, you will charge tooling according to the cost of tooling.n additionalif the cost of tooling is more than 1000 USD, we willreturn all of them to you in the future when purchasing orderquantity reach certain quantity our company rule.
4. How long you will get sample of rubber part?
Jsually it is up to complexity degree of rubber part. Usually it take 7 to 10work days.
5. How many your company product rubber parts?
it is up to the size of tooling and the quantity of cavity of tooling.lf rubber part is more complicate and much bigger, well maybe justnake few, but if rubber part is small and simple, the quantity is more than 200,000pcs.
6.Silicone part meet environment standard?
Dur silicone part are allhigh grade 100% pure silicone material. We can offer you certification ROHS and $GS, FDA. Many of ourproducts are exported to European and American countries., Such as: Straw, rubber diaphragm, food mechanical rubber, etc.
