Engineered Bio. Fluids (EBF) What are Engineered Bio. Fluids? Engineered Bio. Fluids represent a new class of chemical products that are created by developing specialized biopolymers that are specifically designed to have precise reactive molecular sites that provide the ability to have custom tailored, chemical reactions. These revolutionary products are more effective than typical applications and provide environmentally friendly chemistry that is being used in the mining, oil and gas, water treatment, construction and pharmaceutical industries. High Performance Product Engineering (HPPE) is a leader in this new category of biotechnology companies that combine biochemical fermentation and engineering on an industrial scale. HPPE has developed its Engineered Bio. Fluids with the following objectives: § § § Replace traditional chemistry with more effective products Replace traditional chemistry with environmentally friendly products Replace traditional chemistry with lower cost effective products Develop versatile molecular solutions that target specific applications across a wide range of markets Provide customized products and solutions to specific applications © 2016 HPPE.

Engineered Bio. Fluids (EBF) Understanding Engineered Bio. Fluids HPPE combines large-scale production capabilities with precise chemical reactions to deliver Engineered Bio. Fluids in a consistent process on an industrial scale. The first stage of the process is a fermentation and purification phase in a precisely controlled environment to ensure the consistency of the desired biopolymer formulation. These biopolymers can come in many different forms with precise formulations designed to maximize the type and number of reactive sites to fit the desired application. Next, the biopolymers undergo additional engineering to meet the specific performance requirements of our customers. It is in this stage of the process that the team at HPPE performs additional engineering work at the molecular level to custom tailor the products. These precise molecular selections impart the desired characteristics uniquely changing the biopolymers, creating customized, patented Engineered Bio. Fluids, EBF, for our customers. These products are custom designed to meet the specific performance requirements of some of the most demanding environments in the world – for some of the most demanding customers in the world. We are confident that our Engineered Bio. Fluids can help your company discover unique, cost effective and environmentally superior solutions to some of your most challenging applications. © 2016 HPPE. ALL RIGHTS RESERVED. 3

Comparison to Common Plasticizers [1] Sulphonated melamine formaldehyde condensates (SMF) § 16– 25%+ water reduction § SMF gives little or no retardation (very effective at low temperatures or where early strength is most critical) § Higher temperatures, SMF’s lose workability relatively quickly Sulphonated naphthalene formaldehyde condensates (SNF) § 16– 25%+ water reduction § Tend to entrain air bubbles § SNF is very cost-effective Polycarboxylate ether plasticizers (PCE) § 20– 35%+ water reduction § Relatively expensive § Very effective at lower doses In general, the dosage levels for these plasticizers are typically higher than with conventional water reducers.
