DOWSIL™ 7091 Adhesive Sealant
7091 Adhesive Sealant is a high-performance, one-component adhesive and sealant that provides excellent bonding and sealing properties. It is typically used in construction, automotive, marine, and industrial applications where a strong, flexible bond is required. The product is formulated with a moisture-curing technology that allows it to cure quickly and form a tough, durable bond. It can be used on a variety of surfaces, including metal, glass, plastic, and painted surfaces, and provides excellent adhesion even in harsh environments.
● 7091 Adhesive Sealant has good resistance to water, chemicals, and UV radiation, making it suitable for outdoor applications.
● It also maintains its flexibility over a wide temperature range, which allows it to withstand thermal expansion and contraction.
● It is easy to apply and can be tooled and smoothed with minimal effort.
● It can be used for a variety of applications, such as bonding and sealing seams, joints, and gaps in construction, automotive, and industrial settings.
● It is available in a variety of colors, including black, white, gray, and clear, making it suitable for a wide range of applications.
● It comes in cartridges, tubes, and bulk packaging, depending on the specific needs of the user.
● Automotive: DOWSIL™ 7091 is ideal for use in automotive applications such as bonding and sealing car components, including windshields, sunroofs, and windows. Its high strength and flexibility make it suitable for use in harsh environments where extreme temperatures and vibrations are common.
● Construction: DOWSIL™ 7091 is also used in the construction industry for sealing and bonding applications. It can be used to seal joints and gaps in various construction materials such as concrete, metal, and glass. It is also suitable for bonding metal panels, roofing sheets, and other construction materials.
● Electronics: DOWSIL™ 7091 is commonly used in electronic applications as well. Its excellent adhesion to a wide range of substrates makes it suitable for sealing and bonding electronics components and devices. It is also used for sealing and bonding various types of sensors, connectors, and enclosures.
● The useful temperature range of a 7091 adhesive sealant will depend on the specific type of sealant and its composition. In general, however, most adhesive sealants have a useful temperature range that is specified by the manufacturer.
● Silicone sealants: These typically have a useful temperature range of -60°C to 200°C (-76°F to 392°F). Some high-temperature silicone sealants can withstand even higher temperatures.
● Polyurethane sealants: These typically have a useful temperature range of -40°C to 90°C (-40°F to 194°F). Some high-temperature polyurethane sealants can withstand temperatures up to 150°C (302°F).
● Acrylic sealants: These typically have a useful temperature range of -20°C to 80°C (-4°F to 176°F). Some high-temperature acrylic sealants can withstand temperatures up to 120°C (248°F).
● Butyl sealants: These typically have a useful temperature range of -40°C to 90°C (-40°F to 194°F).
● Epoxy sealants: These typically have a useful temperature range of -40°C to 120°C (-40°F to 248°F). Some high-temperature epoxy sealants can withstand temperatures up to 150°C (302°F).
This product has a 12-month shelf life from the date of manufacture when kept in its original, unopened containers at or below 30°C (86°F).
1. Substrate compatibility: DOWSIL™ 7091 Adhesive Sealant is not recommended for use with certain substrates, such as certain plastics and some metals, without proper surface preparation or priming. It's important to ensure that the substrates are compatible and properly prepared before using the adhesive.
2. Cure time: The curing time for this adhesive can vary based on environmental conditions, such as temperature and humidity. It can take up to 24 hours to fully cure, so it's important to allow enough time for the adhesive to cure before subjecting it to stress or load.
3. Joint movement: While DOWSIL™ 7091 Adhesive Sealant has some flexibility, it is not recommended for applications where large joint movements are expected. If joint movement is anticipated, a more flexible adhesive may be necessary.
4. Paintability: While DOWSIL™ 7091 Adhesive Sealant can be painted over, it may require a primer and testing to ensure compatibility with the paint system being used.
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.
