The invention relates to smossyvesa dispersion for smoothing fiberglass, polyurethane, polyurethane-polyurea or polyurea, its preparation and dressing for fiberglass.

It is known, for example, from patent US-A 4255317 the use of dispersions of polyurethane, for example, for the manufacture of fiberglass. Also, for example, from EP-A 792900 known application components hardener on the blocked polyisocyanate in combination with the polyurethane dispersion. Smossyvesa dispersion there is not described.

In the patent US-A 4387181 described aqueous polyurethane dispersion with the locked butanonoxime isocyanate groups and introduced by dispersion of a diamine, for example, isophorondiamine, but does not specify the use of these dispersions for smoothing. Many described the special method of manufacturing a dispersion, which contains blocked isocyanate groups, for example, by lengthening the chains due to the 12-hour reaction with the diamine at a temperature of 70°C. Due to this, there macromolecular dispersion, which cannot be subsequent stitching. Dispersion is of little use in dressing glass.

In the patent US-A 5563208 describes the variance-based varnish, where the solidified on the substrate is performed by polyamine. Here pisaniello low molecular weight prepolymers with blocked isocyanate groups in approaching the three-building, which is implemented by using, for example, MDI, as crude MDI (4,4-methylene-bis-(phenylisocyanate)) or containing isocyanate groups lacquer MDI based on 1,6-diisocyanatohexane. The suitability of such products for smoothing is not specified.

In the patent US-A 5300556 describes a method of making aqueous dispersions that contain the blocked polyisocyanates and compounds polyhydroxy. When a water dispersion of a hydrophilic polyisocyanate is converted blocking means in the presence of polyhydroxylated compounds. When you want to apply a blocking means, which has a higher reactivity than water and polyhydroxylated connection. This represents a significant constraint optimization and extremely difficult transformation in technical scale, because it is quite possible reaction of isocyanate with water. The suitability of such products for smoothing also not specified.

In addition, from patent US 5738912 known aqueous dispersions based on containing essential and ionic groups of the blocked NCO-prepolymerisation and polyamine, and polyamine Aii) as cross-linking component are added separately to the blocked JI-prepolymerized Ai).

The presence of blocked isocyanate groups and reactive hydroxyl or amino groups in the same monomer obvious way leads to improved properties relating to the strengthening and resistance to hydrolysis, as well as processing properties, for example, the bulk density.

Further it has been found that such dispersions are providing additional benefits. No costs for separate storage of the dispersion and curing agent, it is possible huts in order to avoid difficulties or unsatisfactory properties dressing, which may arise due to inaccurate mixing of the dispersion and hardener. There is no problem of incompatibility, which can appear between different dispersions and hardeners or when mixing or during the temperature increase in the application.

Thus, the problem is solved smossyvesa dispersion for smoothing fiberglass, polyurethane, polyurethane-polyurea or polyurea containing associated with polymer blocked isocyanate groups, and optionally associated with the polymer capable of reacting with hydroxyl or amino group, which is stable when stored at temperatures up to 50°and at a temperature of from 90°280°sewn.
