The Advantages of Ultra-Low-Viscosity HDI Trimer and High-Flexure HDI Prepolymer for Polyaspartic Coatings
This presentation will show how ultra-low-viscosity HDI trimer and high- flexure HDI prepolymer will perform in polyaspartic coatings such as floor, bed liner and heavy corrosion protection, etc. The use of ultra-low-viscosity HDI trimer in polyaspartic coatings maintain coating performance like drying property, hardness, chemical resistance and weatherability while lowering the viscosity of the formulation (while attaining VOC reduction) than the standard viscosity HDI trimer. This is a result of the trimer structure being also the main component. Furthermore, when it is desired to make a non-solvent formulation, the ultra-low-viscosity HDI trimer is considered to be optimum. On the other hand, as a result of applying high-flexure HDI prepolymer to polyaspartic application, it has better flexibility than HDI trimer. Moreover, the high-flexure HDI prepolymer has excellent weatherability that is important for heavy corrosion protection. If necessary, coating performance like drying, hardness and flexibility can be adjusted by using a blend formulation of the high-flexure HDI prepolymer and low-viscosity HDI trimer.
