Borchi® Set Paste UZ 2
Thickener for paints with heavy pigments
Description
Borchi® Set Paste UZ is an anti-settling agent which also acts as a viscosity adjuster. Borchi® Set Paste UZ is suitable for use in paints containing solvents and effectively inhibits formation of hard sediment, even when heavy pigments are used.
Properties
- Easy to incorporate with conventional high-shear dispersing machines.
- Thickening and thixotropic effects unaffected by temperature.
- Wetting of pigments and fillers or metal powders.
- Reduces a paint's tendency to run on vertical surfaces.
- Higher film strength during application.
- Considerably reduces gas formation with zinc-rich paints.
- No effect on drying, hardness, gloss and weathering resistance.
Applications
With its anti-settling action, Borchi® Set Paste UZ is an excellent suspending agent for pigments and fillers. lt is also highly effective when used with heavy pigments and metal powders, offering particular advantages in zinc-rich paints for example.
Borchi® Set Paste UZ is an effective thixotropic agent and thickener for paints based on cold-curing epoxy resins, epoxy resin esters, alkyd resins, chlorinated and cyclised rubber, DD systems, vinyl resin polymers and copolymers.
Mixing and addition rate
Although Borchi® Set Paste UZ can be incorporated into paints by all conventional means, addition of the paste to the mill base is recommended. For its incorporation into zinc-rich paints, a high-speed mixer should be used.
Empirically determined addition rates are generally between 1 and 3%. The optimum addition rate depending on the nature and extent of the tendency towards sedimentation should nevertheless be determined beforehand in trials.
