ABSTRACT:
A silane coupling agent of either ambi or monofunctional type, and/or an isopropyl titanate coupling agent of either ambi or monofunctional type; and/or, a glass resin thermoset silicone coupling agent of either ambi or monofunctional type which is refined siloxane chain/s with select OH groups in a carrier solution is and are sprayed or poured into hydrophilic particulate and/or fibrous, crystalline and/or amorphous inorganic substances or compounds in a high intensity mixing apparatus between about 70.degree. F. and 350.degree. F. and a silane coupling agent of either ambi or monofunctional; and/or an isopropyl titanate coupling agent of either ambi or monofunctional type; and/or, a glass resin thermoset silicone coupling agent of either ambi or monofunctional type which is refined siloxane chain/s with select OH groups in a carrier solution and hydrophilic particulate and/or fibrous, crystalline and/or amorphous inorganic substances are allowed to remain in situ at a temperature between 70.degree. F. and 350.degree. F. for at least about 1 minute.
