DICAP® 2020 is a linear saturated polyester diol with a pendant carboxylic functional group.
The OH terminated polyester chains are DMPA®
Dimethylolpropionic acid initiated polycaprolactone.
The combination of both hydroxyl and carboxyl functionalities produces unique benefits and versatility.
The acid group promotes water dispersability of the resin after neutralisation with a base or can improve adhesion to difficult substrates.

DICAP® 2020 - Technical Datasheet
Applications
DICAP® 2020 can be used in combination with polyester, polyether, acrylic or polycarbonate polyols to formulate pre-polymers for polyurethane dispersions without DMPA.
Since no DMPA is required to formulate water dispersible pre-polymers, NMP may be reduced or eliminated from the formulations. Pre-polymers formulated with DICAP® products have very good solubility in monomers for hybrid applications and in acetone for solvent-free PUDs.
Depending on the molecular weight of the DICAP® polyol and the formulating technique, hard films can be formulated for durable coatings or soft urethane polymers can be formulated for coating textiles and leathers.
DICAP® products can be used in compliance with 21CFR 175.105 for indirect contact with food.
Solubility
DICAP® 2020 is soluble in aromatic hydrocarbons, esters, ether esters, ketones and TBAC. It is insoluble in aliphatic hydrocarbon solvents. Most solutions will stay liquid at 25°C at 50% solids. Higher concentrations require gentle heating to remain liquid.
Packaging
DICAP® products are available in 200kg open head lined steel drums.
Shipping, Storage & Handling
DICAP® 2020 is supplied as a waxy solid that can be easily melted with steam or in a hotbox for easy handling.

DMPA® Brand of Dimethylolpropionic Acid - Product Technical Guide
Introduction
DMPA® Brand of Dimethylolpropionic Acid is a unique and versatile hindered diol molecule with both hydroxyl and carboxyl functionality.
The neopentyl structure of this trifunctional compound, having two primary hydroxyl groups and one tertiary carboxylic group, permits simplified processing by allowing the combining of all reactants in a single kettle charge. Good control of the reaction is possible due to the slower esterification rate of the tertiary carboxyl, assuring a uniform distribution of carboxyl groups along the resin backbone.
The free acid group actively promotes resin water solubility or water dispersability after neutralization with a base, easily introduces a polar group to improve coating adhesion and synthetic fibre dye receptivity, and increases the alkali solubility of deposited films.
DMPA is an odourless, free flowing white crystalline solid which provides superior advantages in the formulation and processing of water soluble resins.
Uses
DMPA is widely used in:
• Aqueous urethane dispersions, resulting in fast air-drying, high gloss waterborne coatings with superior toughness and flexibility.
• Water soluble alkyd and polyester resins for improved hydrolytic stability, minimal coupling solvent and improved early water spot resistance in air dried resins.
• Powder coatings as a modifier for improved gloss, impact resistance and flow properties in epoxy-polyester systems. In polyester blocked isocyanate systems, DMPA imparts a high melting point hydroxyl functional reactive diluent for improved coating flexibility.

DMPA® Polyol HA-0135 is a low molecular weight linear polyester polyol that contains primary hydroxyl and tertiary carboxyl groups in the terminal positions.
The fact that the DMPA is built into a polymeric polyol eliminates the crystalline properties associated with pure DMPA and as a result, formulating low VOC PUDs with a solvent-free process is much easier.
At 25°C, DMPA® Polyol HA-0135 is a viscous liquid; however, when mild heat is applied, the viscosity of the resin decreases rapidly. DMPA®
Polyol HA-0135 has a unique structure that provides excellent hydrolytic stability in PUD formulations.
To illustrate the benefits and properties of DMPA® Polyol HA-0135 in PUD formulations, a low VOC PUD formulation utilizing a solvent-free process is provided.

Dispersion Procedure
Neutralization and dispersing pre-polymer:
1. At 75°C, begin transferring pre-polymer solution to dispersing vessel equipped with high-speed dispersing agitator. Begin agitation on low to medium speed and charge triethylamine (TEA). Allow time for TEA to mix in, typically 3-5 minutes for a 1000g lab batch.
2. Increase agitator speed to 800-1000 rpm and begin charging de-ionized water at a rate sufficient to maintain a vortex. Once water is in and the resin is dispersed, reduce agitator speed and rapidly cool to 25-30°C.

DMPA® Polyol HA-0135 - Technical Bulletin #6
Chain Extension:
3. While dispersion is cooling, pre-mix ethylene diamine (EDA) and second charge of water.
4. Once the dispersion is below 30°C, begin agitation of EDA and water. Note: it is best to start addition slowly then gradually increase rate if viscosity is stable. If viscosity increases, stop addition until viscosity reduces. If viscosity does not reduce after 1- 2 minutes, add more de-ionized water in small increments until it does. Repeat process if viscosity continues to increase during chain extension.
5. Once all the EDA water pre-mix is in, reduce agitator speed to 300-400 rpm and continue mixing for approx. 20 minutes.

3. While dispersion is cooling, pre-mix ethylene diamine (EDA) and second charge of water.
4. Once the dispersion is below 30°C, begin addition of EDA / water mixture. Note: it is best to start addition slowly then gradually increase rate if viscosity is stable. If viscosity increases, stop addition until viscosity decreases. If viscosity does not decrease after 1-2 minutes, add more de-ionized water in small increments until it does. Repeat process if viscosity continues to increase during chain extension.
5. Once all the EDA / water mixture is in, reduce agitator speed to 300-400 rpm and continue mixing for approx. 20 minutes.
6. After 20 minutes, stop agitation and transfer dispersion to a new container and hold for one day before adjusting pH and characterizing dispersion. Note: the one day hold is to allow for entrained air to escape.

DCPD and DCPD resins are common raw materials to both coatings and composite resin formulators. DCPD resins are recognised for a variety of properties such as tackifying, pigment dispersing and moisture / corrosion resistance. Most DCPD based resins are used in non-aqueous applications due to their limited functionality and extremely hydrophobic character. Through a unique process, a hydroxyl functional polymeric DCPD polyol - DMPA® Polyol HC-0123 - is now available. This resin allows formulators to take advantage of the properties of DCPD in a variety of resin formulations through the reactivity of the hydroxyl groups. DMPA® Polyol HC-0123 can be used to prepare both solvent-borne and water-borne resins, including polyurethane dispersions.

Uses
TRIMET® TME is widely used as a raw material for alkyd and polyester resins. Because of their stable neopentyl structure, TME-based resins offer superior resistance to the destructive influences of heat, moisture and light. TME-based alkyds also exhibit faster drying times and better hardness than corresponding alkyds prepared with other polyols. Trimethylolethane has been shown to provide superior corrosion protection, improved gloss retention, better abrasion resistance, reduced discolouration and improved temperature resistance in coating resins compared to those made with trimethylolpropane (TMP).
Oil-free polyester resins made with TME are noted for their excellent colour retention. Siliconized polyesters made with TME offer improved heat resistance and weather resistance compared to other polyols. Both alkyd and polyester resins may be advantageously combined with melamine resins to produce outstanding baking enamels. Those made with TME retain their white colour and gloss exceedingly well even when subjected to severe overbake.
TME esters may be used as lubricant base stocks of plasticizers. Short chain aliphatic esters may be used in polyols ester synthetic lubricants that must withstand high temperatures. Small amounts of antioxidants and corrosion inhibitors are incorporated in the finished lubricant. TME esters are also of value as textile lubricants and are reportedly useful as non-caloric shortenings for food. Due to improved stability, TME triacetate is preferred over triacetin as a specialty plasticizer. TME tribenzoate has been cleared by the US Food and Drug Administration as an additive for adhesives in contact with food.
TME is a preferred surface treatment for titanium dioxide and other inorganic pigments. Use of TME as a solid phase energy storage medium was studied. Typical applications include solar energy storage devices, insulating fabrics, heat storing building products and food warming devices.
Additional data on uses of TME and patent references can be found in “A Complete Guide to TRIMET® Brand of Trimethylolethane” which can be obtained through your GEO Specialty Chemicals, Paints & Coatings Group customer service representative.
Toxicity
TME is essentially non-toxic. The LD50 in mice is greater than 5000mg / kg. TME is mildly irritating to abraded skin with a score of 0.6 in the Draize test. TME is not irritating to the eye with a score 0.0 in the Draize test. No toxicological or allergenic problems have been noted during our many years of production experience.
Shipping, Handling & Storage
TRIMET® TME is packaged in 50lb and 25kg multi-wall paper bags with HDPE liners. Super sacks containing 500kg / 1102lb and lined with antistatic LDPE are also available.

Introduction
TRIMET® Brand of Trimethylolethane (TME), manufactured by GEO Specialty Chemicals Inc., Paints & Coatings Group, is a polyol useful in the preparation of polyester resins for a variety of applications.
TME’s favourable properties arise from its neopentyl structure. The three hydroxyls of TME are primary, and therefore highly reactive. In addition, the central carbon of TME, which is beta to all the hydroxyls, has no hydrogens. The absence of beta hydrogens blocks the elimination process, a common mode of thermal decomposition in polyols. Also, the hydrogens in the alpha position relative to the hydroxyls are adjacent to the highly branched central carbon atom, therefore they are highly hindered and protected from free radical attack. The combination of these factors makes TME a very desirable component of coating compositions where good thermal resistance properties are required.
This Technical Bulletin illustrates the use of TME in the preparation of silicone modified polyesters intended for high temperature resistant industrial and bake ware coating applications.
