RC-920-Product manual

The RC-920 pre-activated polyamide wax paste series is prepared by pre-dispersing and activating the polyamide wax powder in an organic solvent to form a thixotropic paste. It is specially designed for solvent-based paint coating systems, effectively establishing thixotropic viscosity in the system, controlling sag and anti-settling, and providing effective help for the orientation and coordination of aluminum powder and copper powder in metallic pigment systems.

Features

Compared with other rheological additives, it has the following advantages:

1. Better thixotropy, sag resistance and anti-settling properties.

2. Wide application temperature range (20°C-70°C) without heat activation.

3. It does not ruminate, easy to produce and reduce costs.

4. Does not affect the gloss and weather resistance of the paint film.

5. It is easy to disperse and can be dispersed in a high speed disperser without grinding. It can be added after pre-forming the gel solution.

6. Help the orientation and coordination of aluminum powder, gold powder and pearlescent pigments to enhance their sparkling effect.

Application areas: 


RC series polyamide wax paste is suitable for all kinds of industrial and civil solvent-based paints, such as acrylic resin, unsaturated polyester paint, chlorinated rubber paint, epoxy resin paint, vinyl resin paint, amino resin paint and other industries. Two-component baking varnish, as well as inks, sealants and more. Suitable solvent systems include aromatic hydrocarbons, esters, ethers and alcohols.

 

Use and storage methods:

 

1. It is recommended to use a pre-gel method to pre-mix the wax slurry and solvent to make a pre-gel.

2. Pre-dispersion equipment should use high-speed disperser, do not use high-shear equipment such as sand mill.

3. The pre-dispersion temperature is generally from 20 ° C to 40 ° C for a period of from 30 to 40 minutes.

4. Store in a cool, well-ventilated place away from fire. The container remains sealed.

 

Processing temperature:

 

Aliphatic / aromatic / oxygenated solvent: 35-70 ° C

The higher the solvent polarity, the lower the processing temperature requirements.
