Product Description

One-part silicone rubber products – RTV-1

are ready to use. They cure at room temperature and are ideal for bonding, or sealing and encapsulation.

Fong Yong SFR-8200 silicone sealants are key players: ready-to-use compounds that have been tailored to the specific demands in electrical and electronics sectors..


SFR-8200 is a high viscous flame resistant one-part RTV silicone sealant. It exhibits good adhesion properties to most materials, such as transportation tools, boat, airplane, metals, glass, ceramics and electronic devices. SFR-8200 cures at room
temperature on exposure to moisture in the air to form elastomer. It does not generate heat neither corrosive acetic acid by-product while curing. It has wide service temperature range, and exhibits excellent weather resistance and dielectric
properties, suitable for electric and electronic evices as waterproof sealant.


1. Neutral, no acidic corrosive by-product.
2. Easy operation (premixing and heating are not equired).
3. Short skin over time (15~20min).
4. Excellent adhesion properties for a variety of aterials.
5. Wide service temperature range (-50℃ ~ +200).
6. UL94V0 approval (E120665).

What is an RTV Silicone?
An RTV (Room Temperature Vulcanization)  silicone sealant is a sealant that begins to cure immediately upon being exposed to air (specifically the moisture present in the air), as opposed to water based sealants such latex.


What colors do silicone sealants come in?
SFR-8200 is available in any color required.


At what temperature can silicone caulk be applied?
SFR-8200 can be applied at room temperature. Regardless of temperature, it is important to ensure the surface be clean, dry, free of frost (for cold weather applications) for proper adherence to occur.


Do I need to use different caulk products for different jobs?
Yes. Caulks differ in their formulations, and their intended use. Properties like adhesion, flexibility, elasticity, and durability vary substantially from product to product so it is important to select the right product for each job.

If you need to know the best caulk to use for your application, contact us http://www.fongyong.com.tw. We will be happy to help you select the best product(s) to your application.


What does the term “Skinning Over” mean?
Skinning over means that the product has begun to cure and has developed a firm skin formation on the surface.


How do I store silicone caulk?

1.     Remove the screw on nozzle, and make sure any air is removed by pushing the caulk to the tip of the cartridge before replacing the screw on nozzle.

2.     Replace the removable tip.

3.      Store in a cool, dry environment.


Once I have applied the caulk, how long do I need to wait for it to cure?
Typically, our SFR-8200 silicone (and other silicone sealants) will cure in 24 hours. Of course, this cure time could vary depending on environmental factors – primarily the moisture in the air. Since SFR-8200 is a moisture curing silicone sealant, it relies on the moisture in the air to cure. Lack of humidity will extend the curing process, and could take up to 48 hours.
