Rosin Powder

Some applications of rosin require the use of rosin in the form of powder or dust. Such applications usually intend to improve grip, increase friction or prevent slipping. There are two quite different types of rosin powder available for such applications.

  1. Powdered natural pine rosin
  2. Synthetic rosin powder

These two products are completely different in terms of their chemistry and molecular structure. They only share some physical properties such as grip improvement. Both natural and synthetic rosin are common ingredients of many adhesives.

Natural Rosin Powder

Natural pine rosin can be ground to powder; however, the powder particles will soon stick to each other and form a solid chunk again. To avoid this problem, some anti-caking powder must be added to natural rosin powder.

CAS No: 8050-09-7rosin-powder-large

The natural rosin powder supplied by RosinFactory and ChemicalStore contain about 10 to 20 percent magnesium carbonate (food and pharmaceutical grade) as anti-caking agent. The Material Safety Datasheet of Powdered Natural Pine Rosin is available in PDF format. Please review the MSDS before use.

Synthetic Rosin Powder

Synthetic rosin powder is a chlorinated paraffin wax. It melts like natural gum rosin and solidifies in the form of clear amber chunks. Since the synthetic rosin has a higher softening point, it can remain in powder form without any anti-caking agent.

CAS No: 63449-39-8

Synthetic rosin is mainly used in paints, coatings, rubber, adhesives, polyolefins, textiles & fabrics. MPROSIN is used primarily as a flame retardant and shows excellent synergies with rosin-powder-large-2antimony trioxide. Additionally, ancillary improvements in various grades of rubber have been seen with improvements in both tensile and tear properties. In polyolefins, MPROSIN is generally recommended for use in standard grades of low-density polyethylene. In mineral filled polypropylene composites, MPROSIN has been used as a coupling agent.

MPROSIN is particularly suited for use with alkyd resins. When used in alkyd resin paints, it offers good gloss and retention, rapid surface drying, good adhesion and weathering resistance, and excellent water resistance. It is used in a variety of paint, coatings and adhesives applications, including chlorinated rubber, non-skid paints, in tumescent flame retardant paints, and as a low cost resin extender in traffic paints to additionally improve adhesion, water, oil, gas and chemical resistance.
MPROSIN is an excellent halogen source for flame retarding textiles and fabrics. The products are essentially non-toxic, provide good durability and stability, and impart water resistance.

MPROSIN is soluble in aliphatic and aromatic hydrocarbons, chlorinated hydrocarbons and esters. Cloudy solutions are seen when working with petroleum hydrocarbon solvents at low temperatures, but the films dry clear.
