Orthovinyl lamination resin

Combining stability and user friendliness

Orthovinyl lamination resin is a vinylester-based resin that is easy to process and can be used to fabricate thin-walled, stable laminates.

Due to its structure, it bonds to carbon fibre more effectively than an acrylic resin. This achieves a high degree of stiffness at a low laminate wall thickness, which falls between that of an acrylic resin and that of an epoxy resin.

Nevertheless, Orthovinyl can be processed as quickly and easily as an acrylic resin. The standard Ottobock 617P37=0.150 hardener can be used.

All benefits at a glance

The resin exhibits a slightly yellow tinge in the liquid state which is not, however, visible in the laminate
As with an acrylic resin, the setting time can be reliably determined based on the added hardener and the temperature
Higher degree of stability than an acrylic resin due to better bonding to the reinforcement fibres
Very easy to sand
Excellent balance between matrix and reinforcement material
Can be coloured with Ottobock pigment pastes
Small number of layers possible
Very good impregnation, especially of carbon fibres
The product fulfils all performance and safety requirements for the manufacture of medical devices provided that the prescribed instructions for use are observed
