Beginning in February, Dow Corning brand silicone materials for high performance building will transition to the new DOWSIL brand.

Combining the power of two trusted companies
The DOWSIL product brand name represents the collective experience and combined power of Dow and Dow Corning. You’ll get the same warranty coverage, features and benefits you’ve come to expect from these trusted silicone products.

To simplify the transition, product descriptors that are part of the product names today will remain the same. For example:

Current product name                                            New product name
Dow Corning 983 Structural Glazing Sealant           DOWSIL 983
