A weekly look at new products, innovations
Eastman Chemical Co. has expanded its non-phthalate plasticizer portfolio with the addition of Eastman VersaMax Plus plasticizer.
Eastman said VersaMax Plus is an enhanced, general-purpose, non-phthalate solution that provides better efficiency, improved dry time, lower and stable plastisol viscosity, and faster fusion compared to traditional ortho-phthalate plasticizers and other non-phthalate options. The product is the second in the VersaMax family of plasticizers, according to the company, designed for plastisol manufacturers and dry-blend compounders.
The company claims the product offers improved dry times, faster fusion, enhanced plasticizer compatibility and high efficiency, demonstrating performance consistent to DEHP (di-2-ethylhexyl phthalate) across a variety of Shore A hardness levels while outperforming DINP (diisononyl phthalate).

Master Bond has unveiled MasterSil 910Med, a one-part acetoxy type silicone system that meets USP Class VI specifications for biocompatibility and ISO 10993-5 testing for cytotoxicity. This translucent paste withstands many sterilization methods, including liquid sterilants, gamma radiation and EtO, the company said.
As a silicone, MasterSil 910Med delivers high flexibility and has an elongation of 400-600 percent, according to Masterbond, and it offers reliable thermal cycling and mechanical shock resistance. The company said the bond strength to metals, composites, glass ceramics, rubbers, plastics and other silicone substrates is excellent, and serves the temperature range of -75°F to +400°F. It is an electrical insulator with a volume resistivity of >1015 ohm-cm, Master Bond said.
This single component system cures at room temperature with a tack free time of 10-20 minutes, Master Bond claimed. Curing is based on the humidity level, where the higher the humidity, the faster the cure. In addition, the company said thinner sections cure more quickly than thicker ones.
The firm said MasterSil 910Med is available in 80 gram tubes and has a shelf life of six months.

Momentive Performance Materials Inc. launched CoatOSil DRI waterborne silicone, at the American Coating Conference in Indianapolis earlier this month.
CoatOSil DRI is waterborne silicone that can act either as a co-binder or additive in latex systems, according to the company, and can help water-borne systems reduce water uptake and improve UV resistance.
Momentive has highlighted CoatOSil T-Cure silane oligomer, a mercapto silane with a unique structure that has a very low odor. The company said the material can lead to coating formulations with improved hardness development, corrosion resistance and adhesion to galvanized metal.
CoatOSil, Silquest and A-Link silanes are used to provide improved adhesion and crosslinking in coating systems, and Momentive said CoatOSil copolymers optimize wet out and surface uniformity in these systems.
