How to use Silane Coupling Agent Aminopropyltriethoxysilane Crosile550
ECOPOWER Crosile®550 silane coupling agent, gamma-aminopropyltriethoxysilane, a versatile amino-functional coupling agent may be an excellent candidate for use in a range of broad applications to provide superior bonding between inorganic substrates and organic polymers.
Chemical Formula: H2NCH2CH2CH2Si (OC2H5)3
1. Preprocessing packaging method
Put the filler into the solid mixer (high-speed solid mixer HNSHEL or V-type solid mixer, etc.), spray the above silane solution directly on the filler and stir, the higher the rotation speed, the better the dispersion effect. Generally, stir for 10-30 minutes (the slower the speed, the longer the time), and the filler should be dried at 120 degrees Celsius (2 hours).
2. Silane coupling agent Crosile550 aqueous solution
(Glass fiber surface treatment agent): Glass fiber surface treatment agent often contains: film-forming agent, antistatic agent, surfactant, coupling agent, water. The amount of coupling agent Crosile550 is generally 0.3%-2% of the total glass fiber surface treatment agent. First, the pH value of the 5-fold aqueous solution is adjusted to a certain value with an organic acid or salt. With good agitation, add the silane until clear, then add the rest of the ingredients. For insoluble silanes, isopropanol can be used to aid dissolution. During the drawing process, the glass fiber surface treatment agent is sprayed on the glass fibers and dried to remove the solvent and water.
3.Background Law
5%-20% Silane coupling agent Crosile550 solution is applied to the surface of the substrate by the above-mentioned treatment methods such as coating, brushing, spraying, and dipping. Remove and dry at room temperature for 24 hours, preferably 120°C. 15 minutes.
4. Direct Join Method
Silanes can also be added directly to filler/resin mixtures. When the resin and filler are mixed, the silane can be sprayed directly into the mixture. The amount of coupling agent is generally 0.1%-2% of the amount of filler (determined according to the diameter of the filler). The silane-added resin/filler is then molded (extruded, compression molded, coated, etc.).
