[performance characteristics]
Synthetic leather soft paste moistureproof agent as a kind of hydrophilic reactive polyether modified polysiloxane and waterproofing agent, the waterproof mechanism is capture after reaction with the water, and then achieve the goal of elimination of the influence of moisture in the system. This product has the function of leveling, viscosity reducing, foaming, wetting, emulsification, softness and slippage. It is a good special surfactant.
[technical indicators]
Appearance: pale yellow transparent liquid (low temperature may be turbid or solidified)
Activity: greater than 99%
Solubility: DMF, alcohol, ketone, toluene, esters are completely miscible with water.
Surface tension: 26 ~ 30mN/m.
[usage]
1, used in Pu resin, coating resin accidental introduction of capture moisture, thereby eliminating leather surface because of the water droplets to form a "spot", to ensure product quality, improve the yield of synthetic leather. It can improve the resin-leveling, reduce the shrinkage cavity and pinhole phenomenon, and improve the feel and luster of the leather surface, increase the wear resistance of the fabric, and have the effect of anti-adhesion and dissolving. At the same time, polysiloxane in this product can participate in the reaction of leather materials through active -oh, which can be used to make the leather more flexible and smooth.
