AdditivesAdditives function to reduce the cost of composites products. Along with cost they also work to enhance fire-retardancy, reduce resin shrinkage, improve thermal stability and increase weatherability. These products include fumed silica, alumina trihydrate, calcium carbonate, stearates, glass fiber, ceramic, and thermoplastic microspheres.
CatalystsCatalysts also known as organic peroxides are used to initiate and control the curing process of polyester and vinyl ester thermoset resin systems.
Colorants/PigmentsColorants and pigments can be types of dye, biological pigment, ink, paint, or colored chemicals. Different formulations require a variety of diverse properties that can be provided by various types of colorants and pigments.
Core MaterialsThe purpose of core materials in a composite is to increase thickness of a low-density material. They can increase the stiffness and strength with little additional weight to the composite structure.
Engineered MineralsEngineered materials deliver optical, mechanical, and rheological performance. These minerals additives also help minimize cost.
Epoxy Curing AgentsEpoxy curing agents are widely used in the infrastructure and construction markets. When applied these agents increase the chemical resistance, strength, and temperature performance.
Epoxy ResinsEpoxy resin systems are less flammable, more durable, have a lower shrinkage with longer shelf life and more chemical impact and resistance. This material can be utilized in general purpose adhesives, binders, rigid foams, non-skid coatings, industrial coatings, and plastics.
Fiberglass ReinforcementsFiberglass is typically made from silica-based materials blended with metal oxides. These Formulations may vary based on application needs providing a balance between cost and performance.
GelcoatsThese coating systems can be formulated to meet many composite applications by combining various resins, fillers, colorants and thickening agents. Gelcoats are applied to a mold surfaces to form a protective and cosmetically appealing coating to many composite structures.
Mold Release ProductsMold release agents form a coating that provides a barrier between the mold surface and the product being produced. These mold release systems increase productivity and product quality. Some release agents require elevated temperature cure while others cure under ambient temperature conditions.
Polyester CompoundsPolyester compounds can be engineered to provide void filling, fairing, reinforcement or adhesive requirements to a composite product. A variety of fillers and resins system can be combined to meet a specification.
SolventsA solvent is a liquid with the capability of dissolving another substance. Once the solute is dissolved it creates a solution. Solvents vary by strength, application, and industry.
Structural AdhesivesStructural adhesives are used in constructions to reduce the need for mechanical fasteners. This can improve the structure visually and enhance the overall quality with little change in weight.
ThixotropesThe most commonly used thixotropy is fumed silica. This powder has an extremely low bulk density and high surface area. It’s three-dimensional structure results in increased viscosity when used as a thickener in thermoset polyester resins.
Vinyl Ester ResinCreated for maximum corrosion resistance, vinyl ester resin is a balance between polyester and epoxy resin. This balance gives the product great handling characteristics and properties. Benefits of this hybrid include heat resistance, durability, strength, and low viscosity for easy pouring and vacuum infusion.
