BASF Show New Composite Systems and Coatings at JEC 2011

28 March 2011

BASF will present new composite systems for automotive lightweighting and innovative specialty coatings for wind turbine rotor blades at the Paris JEC Composites Show from March 29 through 31, 2011, in hall 1, booth G 17.

An additional focus this year will be on novel composites based on polyurethane (PUR) and epoxy for automotive lightweight construction.

New systems for lightweight components

BASF is offering new solutions based on epoxy and PUR that are branded Baxxodur and Elastolit R, respectively. Both systems feature similar properties and can be selected individually to match the customer's application conditions and requirements.

The two systems from BASF feature reduced RTM cycle times, with demoulding times of less than five minutes. They function by innovative curing mechanisms which means that they can be processed much longer than conventional products and still cure much faster if required. Both systems are self-releasing and suitable for processing on common high- and low-pressure equipment. BASF say that components made from these materials show excellent thermal and mechanical properties.

The novel epoxy systems for the automotive industry are based on the same innovative principle as the new epoxy systems BASF launched in 2008 for the production of wind turbine blades: the use of so-called latent curing agents offers users in both industries a significantly lengthened pot life while it reduces cycle times at the same time. BASF holds patents for these systems.

Other PUR innovations

The specially developed Elastolit D PUR foam cores are characterized by high compression strength and temperature resistance combined with low density, enabling composite structures with high specific component stiffness and good isolating properties plus low weight.

In its Elastocoat C system, BASF has developed an in-mold coating material for use on commercial high-pressure commercial vehicles, that can be realized cost-effectively by PUR composite spray moulding (PUR-CSM) equipment.

New coating materials

At JEC 2011, BASF presents its new Relest Wind RepKit for onshore and offshore wind energy plants. Along with all the materials and tools necessary for rotor blade repairs, the kit also comprises an application training seminar. The new Relest Wind RepKit has been designed for stationary use on the ground or on wind turbines.

Relest Wind ProcessCoat has been developed to provide effective protection against erosion and UV radiation in rotor blades - one of the products in BASF's coatings range for wind energy applications.
