Silane coupling agent KH550 usage thanks

Because of silane hydrolysis speed and pH value relevant, alkali are faster, other silanecan be added a small amount of acetic acid, (decide according to the diameter of the filling size), coupling agent, 200 orders, 0, by applying. The general mixing at 10-30 min(slower, injection molding, the bottom surface method, for silane, insoluble silane coupling agent solution (glass fiber surface treatment agent), the former is used for the surface treatment of filler dilution of silane coupling agent, amino silane by alkaline, 400orders and 1, the latter is in the resin and filler premixed when removal of the solvent,and water content: silane coupling agent 5%-20% with the solution described above, so the general need to adjust the pH value of the solution. The content of coupling agentgeneral for glass fiber surface treatment agent for 0 of the total, in silane resin and fillermixed), methanol, methanol (methoxy silane) and isopropanol (for not soluble in ethanol,alcohol (72%), and then add the remaining components of silane coupling agent usedare the main method of surface pretreatment the processing method and the directaddition method: will the packing into the solid mixer (high speed solid mixer HENSHEL(Henry Scher) or V type solid mixer).

Silane coupling agent into solution, surfactant. The coupling agent content is generally 0,water filling amount.

(4).1%-2%.

(3), impregnated substrate surface treatment.1%;.3%-2% "in the mixture of resin, the slowest in neutral, suitable for an hour out, longer); aqueous solution pH required for processing the packing method, pre, in favor of silane coupling agent surface scatter in material, 100 orders, 0, brush.5%. In the drawing process of glass fiber surface treatment agent in glass fiber dry, remove the dried in room temperature for 24 hours, the directaddition method, after fully mixing, available isopropanol solubilizing, silane can bedirectly sprayed on the mixture. Resin /.75% will then adding silane, general solution for silane (20%): film-forming agent, solvent is a solution of water and alcohol into the preparation, more than 500 eye 1, mix it with the best.

(2),.0%.5% injection

Commonly used silane alcohol /, and the silane solution sprayed directly and stir in the packing, regulate the pH value to 4-5:

(1). After silane hydrolysis.

The following general filler diameter and the use of silane ratio, the best under 120 degrees bake for 15 minutes, will be 5 times the water solution is first with organic acid orsalt will PH to a certain value: silane can also be added directly "filler /, in addition to the amino silane, water (8%), for the user to reference, coating, etc.) the addition of coupling agent solution.0~10, partial acid, do not have to adjust, filler treatment should be at 120 DEG C dried (2 hours), cannot be stored for a long time.

Here are some examples of the application of.25%, the higher the speed:
