Formulation Additives for Thermoset Composites

Formulation additives impart the optimization of thermoset composites properties by enhancing adhesion, rheology and wetting abilities. BTC’s formulation additives for the thermoset composites comprise of air release agents, wetting and dispersing agents, flow and levelling agents and slip agents.

Air Release Agents

Entrapped air in the thermoset composites matrix affects negatively the composites properties, besides others the porosity, the osmose and the mechanical properties.
Efka® air release agents – properties & applications

Low to Medium Molecular Weight Dispersants

The use of dispersing agents results in increased filler, pigment loading, reduced viscosity and improved flow, increased colour strength and a stable dispersion of the compound.

High Molecular Weight Dispersants

The use of polymeric dispersants results in increased pigment loading and reduced viscosity while improving the flow behaviour, increased colour strength and a stable dispersion compound.

Substrate Wetting Agents and Surface Modifiers

For thermoset composites wetting agents and surface modifiers are used to prevent surface defects during the application of the compound or to optimize the profile of the dry surface.

Performance Additives for Thermoset Composites

Performance additives assist organic substrates such as composites which are exposed to a variety of environmental and artificial factors like radiation, humidity, temperature change, microbiological attack, air pollution and more.

Chemical Intermediates for the Composites Industry

Styrene reduction is an important topic in the composites industry; vinyl monomers can replace a part of it by up to 20 %. Formulators need to balance between the different vinyl monomers of the range by mixing them to obtain the properties expected. Vinyl monomers are used in unsaturated polyester glass fiber reinforced, besides others.
