2 Additives for Grease

Additives for GreaseImprove your Greases with our Polymer AdditivesFUNCTIONAL PRODUCTS INC. offers a variety of polymer additives. Our specialty polymer additives form an interpenetrating physical network with the grease soap to greatly improve the performance of the grease: increased shear stability, enhanced water spray-off and thicker grease.

How do Polymers Improve Grease?The polymer forms an interpenetrating network with the grease soap matrix by chemical bonding, entanglement or an amorphous crystalline reinforcement. The result is improved functional properties and a robust appearance.

Polymer Additives and Low Temperature PropertiesMany of Functional’s polymer additives, including V-207, V-4040P, V-4060, V-4270 and V-191, do not adversely impact low temperature flow properties of lithium complex base greases as determined by Lincoln Ventmeter results. Data available upon request.

Improved Shear StabilityFUNCTIONAL V-4004A, V-207, and V-176 greatly improve Cone Penetration (ASTM D217) and Roll Stability (ASTM D1831) performance test results for grease.

lEnhanced Water Resistance FUNCTIONAL V-4004A, V-4060, V-4040P, V-207, V-4270 and V-176 reduce water spray-off grease loss by as much as 90% (ASTM D4049).

lIncreased Yield FUNCTIONAL V-4004A, V-4040P, V-207, and V-176 stiffen greases and decrease the NLGI grade. To bring the grease back in grade, approximately 10% more oil is added.

What Types of Grease Soap may be Treated with Polymers?Our specialty polymers are compatible with the following mineral and vegetable oil-based grease soaps: aluminum, lithium, lithium complex and calcium sulfonate systems.

Compatibility with Vegetable and Mineral GreasesDifferences between vegetable and mineral oils require the use of compatible polymers when forming greases (see the illustration below). Although both oils are characterized by long hydrocarbon chains, vegetable oils have polar ester groups (A) and unsaturated double bonds (B).

Polymer AdditivesFor Water Spray-off, Water Washout and Shear Stability

Functional’s polymer additives can be used in aluminum, aluminum complex, lithium, lithium complex and calcium sulfonate base greases to improve water resistance and grease yields. These additives are composed of polymers selected for molecular weights that provide optimum benefits in greases. Liquid grease additives are preferred in continuous grease operations.

FUNCTIONAL V-207 and FUNCTIONAL V-4040P are powdered polymers without diluent oil for formulating flexibility that enhance water spray-off and grease yield.

FUNCTIONAL V-4004A is a multifunctional polymer diluted with oil and is designed to improve water resistance and mechanical stability. FUNCTIONAL V-4004A also increases the tackiness of the grease and stiffens the soap matrix, resulting in higher yields.

FUNCTIONAL V-4270 is a mixture of multifunctional polymers specifically designed for use in greases to improve water resistance and mechanical stability. FUNCTIONAL V-4270

also increases the tackiness of the grease and stiffens the soap matrix, resulting in higher yields.

FUNCTIONAL V-4060 is a pellet polymer that improves water spray-off and provides exceptional visual tackiness in grease.

FUNCTIONAL V-4033 is a highly concentrated solution of grafted polymer for use in greases at low treat rates to improve water resistance and mechanical stability. Its liquid form allows quick incorporation into grease without a long dissolving process and results in more consistent results than when using a solid polymer. FUNCTIONAL V-4033 also increases the tackiness of the grease an reduces the required soap content resulting in higher yields.

FUNCTIONAL V-4004A and V-207 are added while cool, at temperatures below 100°C. FUNCTIONAL V-4270 may be added before saporification or while cool, but temperatures above

100°C (212°F) should be avoided. FUNCTIONAL V-4040P is added during the initial reaction stage. FUNCTIONAL V-4033 may be added before saponification or with the cooling oil.

Definitions:

NSF – The NSF, a non-governmental non-profit corporation, assumed respon-sibility from the FDA. Registry numbers are assigned to approved products, lubri-cants and lubricant additives.

HX-1 – The NSF classification HX-1 applies to ingredients with incidentalcontact with food.

HX-2 – The NSF classification HX-2 applies to ingredients with non-foodcontact.

21 CFR 178.3570 – This section of the Code of Federal Regulations applies to Lubricants with Incidental Food Contact.

Tackifiers

Food Grade and Biobased Extreme Pressure Additives

FUNCTIONAL’S tackifiers are based on unique blends of polymers which may be used in a range of greases from aluminum complex to clay. Due to the high molecular weight of the polymer, the tackifier network interpenetrates the grease soap matrix. Tackifiers improve adhesive properties and enhance water spray-off performance.

FUNCTIONAL V-176 confers tack or stringiness to a lubricant, and may be used to provide adherence.

FUNCTIONAL V-191M is a white liquid for use in greases made with water or where water is a by-product of soap formation. As an emulsion, FUNCTIONAL V-191M has a lower viscosity compared to solutions of tackifier polymers in oil.

FUNCTIONAL V-380 tackifier is recommended for high temperature applications 200°+C, where it remains tacky and stable when exposed to high temperature.

FUNCTIONAL V-515 and V-572 are yellow-orange tackifiers for fatty oil-based greases. FUNCTIONAL V-572 is approximately 90% readily biodegradable.

FUNCTIONAL V-584 (NSF registration #120913, category HX-1, HX-2), may be used where incidental food contact may occur.

FUNCTIONAL CERAMAX and CERAMAX PASTE use size-optimized particles to provide efficient and economical products for use in heavy industrial and food processing grease. Both provide lubrication and metal-to-metal protection under extreme loads and temperatures, making them ideal replacements for graphite, MoS2 or PTFE.

Effective performance with either powder or paste can be provided with a treat rate as low as 5%. The end-user should determine the appropriate treat rate for their application.

FUNCTIONAL CERAMAX (NSF registration #143817, category HX-1, HX-2) is a white powder that allows maximum flexibility when formulating your grease.

FUNCTIONAL CERAMAX PASTE (NSF registration #147508, category HX-1, HX-2) is a pre-dispersed mixture for ease of processing and handling.

FUNCTIONAL RD-535 is a liquid additive for biobased grease. At a 5.0% treat rate, RD-535 has a Timken Weld Load of greater than 70 pounds (32kg).
