Help me with Finding a Business Partner

I want to manufacture a chemical additive in India or China. The chemical additive is added to asphalt mixes produced in asphalt mixing plants for the purpose of extending the life of asphalt pavements. Asphalt pavement contractors, asphalt mix producers and asphalt mix material sellers may be interested in chemical additives. The chemical additive patent has been pended in India or China, and has been actually applied to the asphalt pavement construction sites. The chemical additive shows excellent quality (1.5 times better than the regular asphalt pavements) and economically competitive compared to all other products available (most economical price). I am looking for any business partner (or technical licensee, or investor, etc) in India or China to manufacture there for sale. I am looking for $0.4M-$0.5M to do business in India or China. The chemical additive can be applied to the regular asphalt pavements to construct the modified asphalt pavements that extend the life cycle of asphalt pavements. Also, it can be used for the recycled asphalt pavements to improve pavement performance, even 100% RAP-recycled pavements, to eliminate the early damage of pavements.
