Properties & Applications:
The product is nontoxic and insipid. The principle is: as there are large quantity of relatively active Si-H bonds in the molecule, Under the effect of metal salt activator at low temperature it can crosslink to form waterproof film on the surface of various matters.
It can be applied as waterproof for various materials as fabric, glass, ceramic, paper sheet, leather, metal, cement, marble, etc. Especially for fabric waterproof.
It can be used as waterproof agent and softener for fiberglass
It also can be applied in antiadhesion isolating agent and crossinglink agent for paper manufacture.
Use methyl hydrogen silicone fluid together with methyl hydroxide silicone fluid latex can resist water and remain Air’s permeability of the fabric and enhance splitting tensile strength, friction strength and antifouling property and improve the feel and stitching property of the fabric.
Storage and Transportation:
It should be put and stored far away oxidant, acid and edible chemical materials;
It should be adopt protection against explode at storage, don't use tool of producing spark easily;
It should be kept away from fire and heat sources, the temperature in warehouse should be not exceed 30°C;
It should be control packing speed when filling for fearing static;
Transportation: As non-hazardous chemicals;
Quality guarantee period: 12 months. Beyond the time, it still can be used only after the result of recheck is up to this standard.
