Neutral Cure, Low Odour Non Yellowing
|
|
| |
| PRODUCT DESCRIPTION |
WeatherSil NY is a one part, low modulus non yellowing silicone sealant which undergoes a neutral cure when exposed to atmospheric moisture. The resulting rubber like seal exhibits high elasticity and excellent durability against sunlight, UV radiation, rain, snow and temperature extremes. The excellent weather resistance combined with a high movement capability ensures many years of continuous service in building joints and glazing applications.

| Key Product Features
|
WeatherSil NY is a highly versatile sealant which will adhere to many common building materials such as glass, concrete, various metals and painted wood without the use of a primer*.
The sealant is also designed to have excellent adhesion to a broad range of thermoplastics, examples being : ABS, PC**, PVC and PMMA***. WeatherSil NY passes the Lexan ® chemical compatibility test of GE Plastics. It also complies with the stress corrosion test of Röhm when used with Plexiglas®.
* Qualification testing is advised. In certain cases the use of a primer can be required.
** Lexan ® and Makrolon ®
*** GE Bayer Silicones recommends to always clean substrates prior to application. This is especially the case for plastics and in particular PMMA. Isopropylacohol is widely used for cleaning purposes and should be applied using a clean lint free cloth. At least 20 minutes should be allowed for drying before applying sealant.
