Solvent solute of stone protective agent

       Solvent and the solute, protective agent is a specifically designed to protect the stone of the liquid, and is mainly composed of a solute (active ingredients), solvent (diluent) and a small amount of additives.

      1, water refers to water as the dispersion medium protective agent. The solute such protection agent most is methyl silicate alkaline liquid, water soluble silicone hydrophobic agent neutral dispersion, and oil in water emulsion type organic silicon dispersed emulsion and fluorinated acrylic acid aqueous solution. These protective agents are to be used as a carrier of water to carry the effective material inside the stone, once the surface of the stone has a hydrophobic property, once again, the protective agent will be hydrophobic nature of the stone. Not only can not form the effective material of stone pores of the superposition of the agent, but will form a spot on the stone surface, which is a very difficult to get rid of the surface contamination.

        This protective agent can not be re painted, it is difficult to stack. Therefore, in the protective agent construction to pay full attention to, not in the over protective agent after drying and then coated over the second door agent, and should be in the over protective agent has been inhaled stone, but is not dry, timely coated over the second door agent. And so on, can make the stone inside more inhalation of protective agents, the formation of more effective crystallization to increase the performance and effect. Can also be used to soak the protective agent in the stone to reach saturation.

       2 ,solvent type refers to the organic as dispersion medium protective agent, such protective agent of solute is mostly silicone or organic fluorine. These protective agents are different in different solute, and the coating properties and the superposition property are also different. Solvent based silicone protective agent, the solvent and solute formula of this kind of protective agent is reasonable, and the coating is good, and the coating can be added to the self, and the phenomenon of anti penetration can not be generated. Therefore, according to the different needs of the stone for a number of superimposed protection, use more convenient. At the same time, this kind of protective agent can be applied to the stone which is not satisfied with the failure or the effect of the use of the water protective agent, and the effect can be achieved. But to remind the time: it is best to use the same brand or have a more profound understanding of the protective agent to re apply or overlay, so as to avoid discoloration.

       On the basis of organic solvent organic solvent type fluorine door agent, this kind of protective agent has very strong anti oil, at the same time, also has a strong anti permeability, and therefore not suitable for its own weight coating and superposition, the second pass door should be in the over protective agent is not drying before, otherwise will produce anti permeability, not conducive to inhalation of the stone house, but for brushing the water protective agent or solvent type organosilicon protective agent stone if you want to increase the anti oil effect, can be used such protective agent recoat add, the stone to prevent water pollution to prevent oily pollution effect is good.

       As belong to the solvent type acrylic and silicone acrylate resin special protective agent (like the bottom of a stone protective agent) can generally be re painted, won't produce each other is not the phenomenon.

      Stone door agent in the future direction of development: environmental protection, low content of Xoc, with water as the solvent of waterproof, anti oil performance better protective agent products. Such as: water based organic fluorine protective agent.
