Silicone Regular for Spray Foam XH-1685

short description:

WynPUF® is our brand of silicone regulator for PU. Silicone foam control selection is important when developing open-cell and closed-cell spray systems. XH-1685 help to create the performance advantages you need. Silicone surfactant for spray foam is used in a variety of applications, from basement and attic insulation to acoustic insulation and soundproofing. It is also used to fill gaps in walls and ceiling, providing a tight seal to prevent air and moisture from entering the structure. Spray foam can be used to protect pipes from freezing during cold weather.

XH-1685 is equivalent to L-6950, B-8518 in international markets.

Product Details

WynPUF® XH-1685 foam stabilizer is a Si-C bond type of polysiloxane polyether copolymer. It has been originally developed for HCFC, water and hydrocarbons blown polyurethane foams, delivering very good foam stabilization and extremely fine celled foam; however industrial experience has demonstrated that it may also be used as a general-purpose surfactant for other rigid foam applications.
