How Anhydrides Help Achieve High Fiber Loading in Composites

Composites are a crucial part of today’s manufacturing industry. They are used all over the world in just about every modern market imaginable due to their natural strength and durability, as well as their versatility. The biggest advantage composite materials have to offer over others however is the strength-to-weight ratio that most composite materials have to offer. And recent studies have shown that for many common composites, the higher the fiber content within the material, the stronger it will be–high fiber loading in other words. But where do anhydrides fit into this mix?

A Quick Refresher on How Composite Materials are Made

To understand how anhydrides can help improve composite strength, it is important to understand what actually goes into making a composite material. Composites are made from two or more materials with different physical and chemical properties, combined in order to enhance those properties. At their most basic, they consist of flexible fibers with high tensile strength set into a rigid matrix resin system.

Recent studies are showing that the more fiber you can pack into the composite, the higher its strength will be–but most fibers require diluents to achieve the viscosity necessary to get the system. These diluents and additives can help with achieving the right viscosity to form the composite, but everything added to the mix will lower the integrity of the resin system. Furthermore the resin system has to bond well to the fibers while simultaneously wetting them out completely.

Anhydrides offer an Alternative

Anhydrides have the properties necessary to create much higher strengths in composites. Anhydrides generally have a low viscosity coupled with a high mix ratio, making them an excellent choice for creating high fiber content composites. They are also acidic and work extremely well to bond to alkaline sizing. The anhydride also enables the resin system to supplant any surface oils and greases and penetrate into the fiber bundles.They don’t require the diluents that other materials need to achieve the right viscosities, and so will retain far better integrity in the resin system overall. Whether using glass or carbon fiber, filament winding, pultruding or RTM; Broadview’s extensive line of cyclic, bi-cyclic, aromatic and multifunctional anhydrides will provide the properties and performance you desire.

Succinic Anhydride: A Safe and Versatile Building Block for Epoxy Curing Agents and More

Succinic anhydride is a common organic chemical compound used to build all sorts of products across pharmaceuticals, coatings, material science research and development, and much more. Succinic acid, the compound that the anhydride originates from, is a naturally-occurring organic acid, found in all different types of biological systems and one of the US Department of Energy’s top chemicals created from biomass in 2004. Today the succinic anhydride is used as a common environmentally friendly and relatively non-hazardous component in coating and pharmaceutical production.

A Safe Building Block for Pharmaceuticals

In the Pharmaceutical and Vitamin Industries, succinic anhydride is an important building block. Succinic anhydride will react with amines and hydroxyls to improve pharmaceutical and vitamin water solubility and bioavailability. It also introduces a four-carbon dicarboxylic constituent that may offer performance advantages.

A High-Performance Component of Urethanes and Polyesters

In the production of urethane, polyester and acrylic coatings succinic anhydride reacts with polyols to increase carboxylic acid sites. These carboxylic acid sites can react with isocyanates or hydroxyls to form urethanes and polyesters.

Succinic anhydride also serves as a building block for acrylation to create UV cured polyesters and urethanes. These coatings will all have improved moisture resistance, less yellowing, uv light resistance, reduced oxidation and increase low temperature toughness.

A Crucial Ingredient for a Variety of Weather-Resistant Coatings and Epoxies

Succinic anhydride can also be used as a chain extender in the production of urethane and polyester resins with terminal acrylate groups. These resins readily undergo free radical polymerization under UV light to form UV- and weather-resistant outdoor coatings with improved toughness and adhesion.

Succinic anhydride also finds utility as an epoxy curing agent both as a powder dispersed in epoxy resin or as a component in extruded powder coatings. Its slow reactivity coupled with its toughness and weather resistance add greatly to the performance of epoxy coatings and adhesives.

Troubleshooting Epoxy Curing Issues with Anhydrides

Epoxies are used widely for flooring, protective coatings, and electrical filament windings. They offer insulation for electrical components, protect floors in industrial and commercial environments, and are even used on vehicles or walls for improved protection and a long-lasting appearance. However, the epoxy curing process is subject to conditions like temperature and contamination that could impact the quality of the final coating.

Common Epoxy Curing Problems

The result of epoxy curing depends on a few major factors: temperature, curing rate, the presence of moisture or other contaminants, and correct formulation, among others. If the resin cures too quickly it could become brittle and more susceptible to abrasion and impact. Colder temperatures can slow the process, and even prevent it from happening. Moisture, trapped air, and other contaminants can affect the appearance and performance of the coating as well, causing bubbling, peeling, stickiness, or cloudiness.

Specialty Anhydrides that Improve Epoxy Curing

Broadview Technologies helps our customers overcome problems like thermal stability, variable cure rates, and brittleness with anhydrides that we’ve engineered to meet the needs of a variety of epoxy resins. We’ve developed several epoxy curing agents over the years to meet the common challenges of these coatings. Our anhydrides impart thermal stability to the coating, helping it to retain its properties despite varying temperatures. Some of our products are single-component epoxy systems that don’t require additional accelerators that may be toxic or would require more complex mixing. Broadview’s anhydrides also resist shrinkage during curing, maintaining the required precision of the coating.

We also can customize our epoxy curing agents for our customers and create new products on request, if our customers come to us with a particularly unique problem. Our team has decades of combined experience in the industry, and we always welcome a challenge.
