DY-ET113 PU Resin Water Repellent
DY-ET113 PU Resin Water Repellent is a hydrophilic polyether modified polysiloxane copolymer designed for use as water repellent. The polymer has a combination of organo-reactivity from the polyether groups as well as properties typical of a polysiloxane fluid. The active ingredients react with moisture/water to produce hydroxy groups. These hydroxyl groups will bond with the substrates and themselves to produce a hydrophobic treatment that inhibits water absorption into the substrate. Exposure to water before use as a treatment may cause the material to cure in the container.
Pale yellow, transparent liquid (become hazy or solidifying at low temperature)
Active content (%)
Completely soluble in DMF, alcohol, ketone, toluene, and ester. Partially soluble in water.
Surface tension (mN/m)
The product can be used on leather to capture water in leather, avoiding negative reaction which may affect the quality of the leather. It can offer a high level of repellency to water, modifying hand feel and gloss, improving abrasion durability and leveling, reducing shrinkage and pinhole, and imparting anti-blocking and release.
HOW TO USE
1. Application in resin, the advisable use level is 0.2~0.5% of the system
2. Application in PU fabrics, the advisable use level is 0.8%~1.5% of the system.
Normally the DY-ET113 water repellent should be diluted in solvents to 10 times of original volume prior to use.
