K-FLEX® 850S

Hydrobrite® PVC Oil has been approved as a functional equivalent to paraffin wax in the PPI range formulations for high pressure PVC water pipe at concentrations of 1 to 2 phr. Hydrobrite® PVC Oil has been added to TR-2 (PPI PVC Range Composition Listing of Qualified Alternative Ingredients). This product also has NSF International approval and has been listed under Witco Corporation in NSF version 12, issue January 15, 1999. Hydrobrite® PVC Oil serves as an excellent external lubricant for rigid PVC applications including pipe, siding, window profiles, fences and doors. As an external lubricant the oil helps reduce friction between the polymer and metal surfaces. *A patent on Hydrobrite PVC Oil technology has been issued by the U.S. Patent Office.

In particular, the K-FLEX® 850S dibenzoate plasticizer blend is designed for:

• Latex adhesives · ·
• Latex coatings
• Latex caulks and sealants
• Latex overprint varnish and waterborne flexographic ink

Like K-FLEX® DP and 500, K-FLEX® 850S has full FDA approvals for adhesives and was created to maximize on efficiency and cost effectiveness. In coatings K-FLEX® 850S is low in VOC to assist the formulator on issues of VOC reduction. Also, K-FLEX® 850S is considered a low vapor pressure-volatile organic compound (LVP-VOC) by Rule 310 of CARB. This means that K-FLEX® 850S is not considered a VOC in California for applications such as latex caulk. K-FLEX® 850S is not recommended for PVC applications; however, it can be used in other applications such as polysulphide sealants. In the EU K-FLEX® 850S is label-free.
