# PMN Substance Application & Environmental Write up

The PMN substance water solution is used for waterp roofing of inorganic substrates. The PMN substance chemically reacts with the substr ate and becomes part of the substrate. It changes the surface from hydrophilic to hydrophobic. There are many organosilicon based waterproofing products commerci ally available in the market. Most of these products contain organic solvents, up to 80 %, to achieve long term performance (over 10 years). The PMN substance cont ains ethylene glycol as solvent (60%). However it is diluted 10-500 times w ith water depending on the application to achieve same or better performance t han solvent based products. The diluted solution (10 fold dilution) contains less t han 70-g total VOC per 1-Kg and 500 fold dilution contains less than 2-g . While so lvent based product can contain 400 - 800-g VOC per Kg. Therefore waterproofing app lication of the PMN substance reduces VOC 80-99 %. The ease of applicat ion is another factor. The PMN substance is non flammable as a concentrated or a diluted form. The applications of the PMN substance do not require sp ecific handling of the flammable material and the workers are not exposed to toxic v olatile solvent.

The PMN substance can also be used to modify surfac e of the aggregates used for asphalt pavement. The PMN substance reacts with the surface of the aggregate makes them hydrophobic. The PMN substance solution is mix ed with asphalt binder (approx. 0.1 %). When heated asphalt binder is mixe d with hot aggregates the PMN substance is reacted with aggregates and provide be tter adhesion between aggregate and asphalt binder which provide better antistrippi ng properties. The surface modification of the aggregates provides economic an d environmental benefits (i) up to 5 % reduction of asphalt binder requirements, (i i) stronger bonding between asphalt binder and aggregates hence lesser chance of bond f ailure, (iii) surface modification provides waterproofing of the aggregates, resulting better protection against water, snow or ice, (iv) smaller aggregates can be used w ith the larger one, this provides better packing of the road surface hence reduces po thole and (v) all types of aggregates can be used because surface modification provides uniform bondability with asphalt binder.

The PMN substance can also be used for cationic asp halt emulsion in water. It provides better wetting on the soil or aggregate ro ad surface. The PMN substance allows faster drying and better adhesion in the tac k coat or prime coat applications. It allows to reduce residual asphalt content by 20-30 %.PMN Substance Manufacturing in India 100 Kg

# Environmental Fate

The PMN substance is a solid mixture of organosilan e quats. It is supplied as solution in ethylene glycol. This compound has reactive grou ps that can react with inorganic substrates such as soil, stone, aggregates and conc rete etc. These inorganic substrates surface contains silanols groups (Si-OH). The PMN s ubstance chemically reacts with these silanols groups at ambient conditions. The PM N substance treatment of these inorganic substrates forms Siloxane (Si-O-Si) bonds between surface and PMN molecules. Siloxane bond is one of the most stable bonds in nature. Therefore the PMN substance upon reaction creates very stable water r epellent surface modification. This chemically bonded PMN substance does not leach out under normal soil environmental conditions. In presence of water, PMN substance tre ated surface is very stable and also it does not leach out in water. Therefore water doe s not get contaminated upon constant contact with PMN substance treated surfaces. The f ollowing diagram illustrates the partial reaction of PMN substance with silanol grou p on the surface of the inorganic bulk substrate.
