Designer Molecules

Nuvico has synthesised over fifty different Oligomers for use in our range of products. Our latest product contains up to 70% Bio-Renewable carbon.

Step 1 : Molecular Design

• Select mode of molecular assembly

• Required degree and type of cure-functionality for chemical and physical properties and co-polymerisation dynamics

• Functional side groups for compatibility and adhesion

• Component blocks for desired physical properties

• End groups for synthesis reactivity and/or product characteristics such as adhesion and compatibility

Step 2 : Synthesis

• Small scale laboratory synthesis

• Initial reaction profile and progress including inter-step evaluation fo reaction progress

• Preliminary reactivity test of candidate oligomer

• Preliminary evaluation of physical and rheological properties

• Drop-in candidate molecule into test formulation for screening test

• Move to small batch pilot synthesis of molecules that show desired potential and performance

Step 3 : Molecular Characterisation

• Stability during synthesis

• Post-synthesis stability under variable temperature conditions

• Colour and colour stability

• Viscosity and Molecular weight distribution

• Refractive index

• Mechanical Properties; including Tensile Strength, Elongation, Flexural strength and displacement, Elastic and Plastic deformation and Yield Stress.

• Secondary Mechanical properties such as Scratch Resistance, Marring Resistance, Impact resistance

• Chemical properties such as Glass-Point transition, water absorption, chemical and solvent resistance, stain resistance

• Colour and performance stability under accelerated Ultra-Violet ageing
