NYTAL 400 Talc Powder, -325 Mesh

GENERAL DESCRIPTION: NYTAL 400 is an ultrafine -325 mesh New York talc powder. It is suitable for industrial use and has a pure white color. It is best used as an inexpensive filler to extend resin. The use of talc will increase the stiffness and the weight of your cured system. In addition, shrinkage wil be reduced and sanding becomes much easier. Mechanical proprties such as scratch resistance can be used. Talc can also be used to fill voids or as a faring compound. Talc can be used to lubricate molds and prevent surfaces from sticking together, and it retains its lubricatant properties at high temperatures.

APPLICATIONS: In addition to being used as a resin filler, this product has also been successful in several industries.

In the coatings indsutry it is used because it is platy, has high brightness, gloss, smoothness and reduced friction and printability. It has been used as carpet backing, valve rubber or cable insulation.

The hydrophobic surface of talc make it useful as an adsorbing agent for tiny contaminants, or to detackify large particles such as calcium soaps.

In the ceramics and glazing industry, it can be used a low-cost source of magnesia. As a flux in ceramics, talc helps produce a denser body while using lower firing temperatures. Talc is also used in catalyst supports, kiln furniture, electrical porcelain and tiles.

Roofers often use talc as to stabilize melted asphalt for tar paper. Increased fire resistance and weathering are obtained when talc is used in asphalt shingles and roll roofing. To prevent rolls and shingles from sticking together during manufacture and storage, talc is often applied between layers.

In the animal feed industry, talc serves as an anti-caking coating in feed bins and on the food. Because it is non-toxic, the talc is inert when ingested, and thus will not harm livestock.

Talc can also be used in joint compounds and urethane sealants. It is also added to butyl caulks, acrylic sealants and dry wall compounds.

Adding talc provides the following outstanding features when used in Eager Plastics Resin Systems:

1. Increased system weight

Recommended proportions vary. Add NYTAL 1:1 by volume for a thick but pourable liquid, suitable for potting. Two part of talc to one of resin by volume results in a light paste consistency. It is always best to experiment with your particular system. NYTAL also meets the requirements for the following: ASTM 0605, MIL-P-15173A Type A and 52-MA-523b Type II.
