Additives & TC's
Cutting and grinding fluids are often complex chemical compounds, which over time
and with use will degrade. Master Chemical has a sophisticated depletion
analysis procedure, which identifies the constituents which need replenishing.
This can be performed using "tank side adds", generally TC fluids which
are listed in this section.
TRIM® CLEAN B1
Booster for High-performance Spray Cleaning
|
|
|
TRIM® CLEAN B1 is a highly concentrated blend of surfactants (surface-active agents) designed to add cleaning power to high-pressure spray washers without causing excessive foaming. The product may be added to a wide range of TRIM® alkaline cleaners to boost cleaning power.
- CLEAN B1 contains no borates, phosphates, nitrites, or amines
- CLEAN B1 is low foaming when used above 115°F
- This product is an excellent choice where both ferrous and/or copper alloy parts are being processed
- CLEAN B1 will not stain aluminum parts
- CLEAN B1 is odorless
- Highly caustic cleaners often produce “soaps” as a part of their cleaning action; CLEAN B1 is very effective at reducing foam resulting from the formation of these soaps
- Cleaner bath life can often be extended by using small doses of CLEAN B1; this product is particularly effective in removing oily soils, but will not affect the “split” of oils in TRIM® CLEAN 2430.

TRIM® TC 203
pH Adjuster/Emulsion Stabilizer
|
|
|
TRIM® TC 203 is a copper amine additive developed to increase emulsion stability by raising pH.

|
TRIM® TC 211 is an amine based pH adjuster for use in central systems and batch recycling systems to replenish depleted alkalinity in metalworking fluid working solutions.
|
|
|
|
TRIM® TC 220 is a triazine compound that is very effective in maintaining pH and building reserve alkalinity in metalworking fluid working solutions. Controlling pH within the design range of the product and maintaining an appropriate level of reserve alkalinity are key elements in extending sump life, controlling both liquid and vapor phase corrosion, and controlling the particle size and emulsion stability of soluble oils.
|
|
TRIM® TC 227
Metalworking Fluid Additive
|
|
|
TRIM® TC 227 is a mixture of lubricity additives. It is designed to increase the hydrodynamic lubrication of water-miscible cutting and grinding fluids. It is particularly effective in increasing tool life and reducing the forces generated in drilling, tapping, and reaming operations in soft, gummy materials. TC 227 has also been effective as an add to chemical coolants used for roll-form tapping in wrought and extruded aluminum alloys.
- TC 227 is intended for use in water-miscible cutting and grinding fluids.
- TC 227 may not be effective in “cationic fluids”.
- The typical add for this type of product is between 0.5% and 5.0% (5,000 to 50,000 PPM). However, it is best to establish the actual add rate by experimentation in your operations.
- While most of the experimental work with this product has been done in machining, there are indications that it may be very effective in some form-grinding operations.
- TC 227 may cause increased foam.
- TC 227 will be depleted with normal coolant carry-off, so periodic additions of it with the normal coolant makeup will be necessary to ensure consistent performance.

|
TRIM® TC 231
Cleanliness Additive
|
|
|
TRIM® TC 231 will prevent or reduce the formation of carbon (graphite) smut and hard-water soaps often found when machining some cast irons with synthetic coolants. TC 231 is a unique blend of wetting agents and surfactants that help keep the machine, tools, and work piece clean for a safer, more pleasant work environment.
|
|
TRIM® TC 233
Lubricity Additive
|
|
|
TRIM® TC 233 is a dual-purpose additive which is used in synthetic (e.g., TRIM® C270, C275, etc.) and some semisynthetic (e.g., TRIM® SC230, SC235, etc.) coolants. It can increase lubricity for operations such as drilling or tapping. At fluid temperatures above 95ºF (35ºC), it will act as an anti-foam.
- In synthetic and semisynthetic coolants, add rates of 1%-3% may be effective in reducing friction in operations such as drilling or tapping.
- If fluid temperature is above 95ºF (35ºC), TC 233 will act as an anti-foam. The add rate for use as an anti-foam is 0.1%-0.5%.
- Typical running time between additions of TC 233 is two to four weeks.
|
|
TRIM® TC 234
Recycling Additive
|
|
|
TRIM® TC 234 is a mixture of chemicals to replace the materials that may be preferentially depleted in some (cationic) synthetic and semisynthetic products. Some of these products have such low carryoff that normal make-up will not replace all of the materials which are depleted over long periods of use. When TC 234 is used as part of a comprehensive recycling or coolant management program, it will replace and/or enhance both the ferrous and nonferrous corrosion inhibition systems of coolant working solutions.
|
|
TRIM® TC 239
Paintable Antifoam/Defoamer
|
|
|
TRIM® TC 239 is a paintable, platable additive used to control foam in metalworking fluids and parts washing systems.
- The maximum add rate is one gallon per thousand gallons of sump volume. You may find that using less than this will be effective in your system.
- For best results, pre-mix TC 239 with working solution until it is water-thin. This mixture should then be added just up-stream from the foam.
- Spraying pre-mixed TC 239 directly onto the foam will knock it down quickly.
- Using too much TC 239 can cause increased foam and/or form a residue on the machine, parts, or tools.
- Shake or stir well before adding. If you make a dilution with working solution, shake or stir that mixture also before adding.
- Do not freeze or store above 115ºF.

|
TRIM® TC 248
pH Adjuster – PMC#9366
|
|
|
TRIM® TC 248 is an amine-based pH adjuster used to replenish depleted alkalinity in metalworking fluid working solutions.
- TC 248 is usually added at concentrations between 0.05% - 0.25% (50 – 2,500 ppm) to help maintain pH, improve corrosion inhibition, and improve emulsion stability. A 0.1% add of TRIM TC 248 will typically increase the pH of a 7.0 pH fluid to approximately 8.0 - 8.5.
- Overuse of this product may cause ammonia and/or amine blush; therefore, care should be taken not to exceed recommended add rates.
- As formulated, TC 248 does not contain MEA, DEA, TEA, Cu, or Boron.
|
|
TRIM® TC 249
Recycling Additive
|
|
|
TRIM® TC 249 is a synthetic recycling additive especially useful in TRIM® SC410, TRIM® SC610, or CoolPAK™ ALW systems with high-particulate loads.
