as we all know, PU polyurethane resin is a kind of common printing paste resin, PU resin commonly used include polyester and polyether type, micro nano Amy with polyether polyurethane resin, T307 transparent powder as raw material, the results obtained by repeated tests, T307 transparent powder, can be directly added to the polyether PU resin, transparent powder adding amount of 15-25%, the emulsion resin / transparency with the original PU resin is very close to the solid content increased, can be used for the preparation of transparent printing paste, improve mortar scrub resistance, but also greatly reduce the amount of resin, the production cost of straight down.
Why can our transparent powder be added directly to the PU resin? I've never heard of it before The reason is simple, before the transparent powder on the market is not transparent, quality is not pass. The problem of Amy micro nano 3 points on:
1, the pre process, you can add: printing paste is a mixture of resin, fillers, additives, pigments, solvents and dispersion, we just keep feeding changed, adding filler to pre process, transparent paste to PU resins. The principle is feasible and the fact proves feasible.
2, does not affect the resin transparency and light transmittance, can add: T307 transparent powder, good transparency, high transmittance, add the appropriate amount to PU resin which does not affect the transparency of the resin, but also increase the solid content of resin, improve the plumpness and resin weathering resistance and washing resistance.
3, low oil absorption value, high dosage, can add: T307 transparent powder is a new product for Amy micro nano transparent launched, adding much more than other transparent powder. Available contents of common transparent transparent powder is generally not more than 10%, Amy micro nano T307 powder is added to the transparent PU resin which can do 15-25% do not affect the transparency and performance, finally made the content of 25-40% transparent transparent powder.
