Alternative Cure Systems for RTV Silicone Sealants

We use RTV silicones in our assembly operations, and our workers keep complaining about the strong vinegar smell. Somebody told me that we might be able to get low-odor, low-volatile silicones. What issues should we be aware of?

Dave Dunn Ph.D.

Room-temperature vulcanizing (RTV) silicones are well-known for their extreme durability. They are convenient one-component sealants that cure by reaction with moisture from the atmosphere.

Pressure-sensitive adhesives (PSAs) offer easy application and secure bonding, including adhering wound care dressings to skin. Skin is a variable substrate, however, and consideration must be given to various skin types to ensure dressings can be securely attached and easily removed without skin damage.

Bonding Polystyrene Foam

We want to bond sheets of polystyrene foam to steel and to wood. What adhesives would you recommend that will be effective and safe to use?

Dave Dunn Ph.D.

November 19, 2021

Bonding polystyrene foam to steel and wood is an application that was traditionally done with contact cements or other solvent-based adhesives. Due to health and flammability concerns, however, the modern trend is to use 100% reactive systems.

Moving the Adhesives and Sealants Industry Forward

The adhesives and sealants industry relies heavily on distributors for far more than simply raw materials and chemicals shipments.

According to a recent report from Grand View Research, the global chemical distribution market was estimated to be $247.1 billion last year and is projected to see robust growth (5.4% CAGR) to 2028. The distribution of specialty chemicals, such as those used in CASE (coatings, adhesives, sealants, and elastomers) and other sectors, is expected to be the fastest-growing segment of the market, reaching $139 billion in that timeframe.

Bonding Fluoroplastic Parts to Metals

We manufacture PTFE and other fluoroplastic parts. We have been requested to make parts that can be bonded to metals. Is there a good adhesive, some sort of additive to the PTFE, or a surface treatment that we can use?

Dave Dunn Ph.D.

September 21, 2021

Polytetrafluoroethylene (PTFE) is a high-performance plastic used in a variety of industries, particularly for its heat and chemical resistance and “non-stick” properties. However, PTFE has a low surface energy that does not allow adhesives to wet its surface and subsequently bond.
