Archer RC™: Technology for Coatings with Reduced VOC Content

Fatty acid ester alcohol that acts as a coalescing agent and reactive diluent in alkyd and latex paints. This product is based on sustainable technology and uses renewable triglycerides (unsaturated fatty acid) as feedstock. These renewable triglycerides facilitate film formation and remain as part of the coating by incorporating the VOCs into the paint coating as fatty acid esters. The product is made by the interestification of vegetable oil fatty acid esters and propylene glycol to monoesters of the fatty acids.

Primer Paints for Automobiles Developed with a Urethan Acylate Oligomer Primer

UV-curable, one-component, low VOC automobile paint primer. This primer is made through a new urethane acrylate oligomer primer system. The primer cures in minutes from UV light, which is ten times faster than conventional urethane technologies. The primer requires fewer preparation steps, has a lower application rate, is more durable, controls corrosion better, and has an unlimited shelf life. This automobile paint primer contains less than half the amount of VOCs in conventional primers and is diisocyanate-free (a major source of occupational asthma).

Chempol® MPS Resins and Sefose® Sucrose Esters for Low-VOCs Alkyd Paints and Coatings

Chempol® MPS paint formulations using biobased Sefose® oils. Chempol® MPS is a Sefose®-based alkyd resin technology that enables paint and coating formulation with less than half the VOCs of traditional alkyd paints and coatings. Sefose® oils are made from sugar and vegetable oil and serve as a viable alternative to petroleum-based solvents. They enable new high-performance alkyd paints with less than half the solvent. Using less hazardous solvents in paint improves worker safety, reduces indoor fumes, and improves air quality.

Water-Based Acrylic Alkyd Paints

Alkyd paint from recycled plastic bottles (PET), acrylics, and soybean oil with low concentrations of VOCs. Traditional alkyd paints are made with a solvent-borne coating and constituents of the petroleum industry. PET is incorporated in a polymeric alkyd-acrylic dispersion (LAAD), which gives the paint more rigidity, hardness, and hydrolytic resistance. Acrylic decreases the drying time and increases durability. Soybean oil stimulates film formation and improves floss, flexibility, and paint cure.

ULTIMER™

Eliminates the use of oil and surfactants in water treatment. Polyacrylamides are used in water treatment and food production. In water treatment, polyacrylamides facilitate the removal of compounds in suspension and the segregation of the mixture. The production of these polymers generates large volumes of organic and surfactant waste (90 million pounds annually) due to the use of oils and surfactants. Nalco developed a new synthetic methodology that eliminates the need for oil and surfactants in water treatment.

Citropol® and Sustainable Ingredients

Ingredients for flavors, fragrances, cosmetics, personal care products, and specialty materials. P2 Science transformers terpenes from the forest and oleochemicals from the field into safe, renewable, high performance, biodegradable, and multi-functional new ingredients for flavors, fragrances, cosmetics, personal care products, and specialty materials. Citropol® is a novel class of low MW liquid polymers that are made from 100% forest-derived terpenes through a clean, mild, and high yielding conversion process.

ZEORORA® H/HTA

Fluorinated, nonflammable, environmentally friendly solvent. ZEORORA® H is a nonflammable and environmentally friendly solvent for a variety of applications.  ZEORORA® H/HTA is a cleaning solvent and functions as an alternative to HCFC-225 and nPB. This solvent has zero ozone depletion potential, minimal global warming potential, and a short atmospheric lifetime. It is also thermally stable, easy to recover, and has a high boiling point and low consumption.

Three-Steps, One-Pot Synthesis for dNTPs in Polymerase Chain Reactions

Manufacturing of polymerase chain reaction (PCR) reagents. PCR is used in research, genetic engineering, forensics, infectious disease identification, food safety, and personalized medicine. The conventional production of key chemicals for PCR tests (such as deoxyribonucleotide triphosphates, or dNTP) is hazardous, inefficient, and not atom economic. This new method for the manufacturing of dNTP consists of only three steps in a single pot, eliminating hazardous reagents and solvents such as zinc chloride, triphenyl phosphine, aldrithiol, dimethyl formamide, and dichloromethane.

No-Clean Soldering

Soldering process that eliminates the use of wave oil and solvents by installing hoods over the solder pots to maintain an inert atmosphere over the molten solder. Conventionally, soldering involves synthetic oil, soldering fluxes, and solvent cleaning (uses large amounts of TCA and TCE). The No-Clean process eliminates the use of wave oil and soldering fluxes, consequently eliminating the need for solvent cleaning. This process reduces the environmental impact of manufacturing solid ceramic resistor networks by reducing the amount of raw materials consumed.
