Resin FAQs

1. How are EPS resins packaged? +

All EPS resins are available in bulk and drums, in addition EPS emulsions are available in standard plastic totes.

2. How should EPS emulsions be stored?+

All EPS emulsions should be protected from freezing and from excessive heat - we recommend storage in the original unopened containers between 5 and 30°C (40 - 90°F). 

3. What can I do if I don’t see a resin I’m looking for on your website?+

EPS can develop custom products to meet specific customer needs - contact your sales representative or customer service for a more in-depth discussion of your requirements.

4. Do EPS emulsions contain a preservative package?+

Yes. EPS only uses formaldehyde free preservatives and strongly recommends the use of additional preservative when formulating finished paints and coatings.

5. I need to reduce VOC in my emulsion paints – can EPS help me?+

Yes! EPS has been developing solutions to deliver excellent performance at low VOC for many years.  Many resins can be formulated to near-zero VOC levels by using the EPS 9147 coalescent.

6. I replaced another resin in my formula with an EPS product and the properties have changed – what should I do?+

In general it is not possible to directly substitue emulsions without some additional reformulation. As a minimum the coalescent and thickener packages should be optimized in order to achieve a similar balance of properties. EPS provides suggested formluations for many of our products which can provide guidance. Contact the technical service department for additional information.

7. What types of resins do you supply?+

EPS supplies a broad range of products including acrylic and styrene-acrylic emulsions, alkyds, polyesters, urethane alkyds and polyurethane dispersions.

14. I keep hearing about PROP 65 and SCAQMD - what are these?+

Proposition 65 is a legislation requiring labelling of all products sold in California that contain chemical compounds known to the state of California to be CMR (Carcinogenic, Mutagenic or Reproductive) toxins. The SCAQMD regulates the VOC levels of paints and coatings (and many other items) in part of Southern California - their regulations are the most stringent in the US.

EPS not only provides products and formulating support to meet VOC targets in formulated paints and coatings but also has a Product Stewardship team that can provide assistance with regulatory compliance to meet federal, state and customer requirements. 

Effective April 22, 2016, the California Office of Environmental Health Hazard Assessment (OEHHA), under the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65), added styrene (CAS No. 100-42-5) to the list of chemicals known to the state of California to cause cancer. Further OEHHA proposed a No Significant Risk Level (NSRL) for styrene of 27 micrograms per day.

Engineered Polymer Solutions (EPS) markets multiple polymers as styrene-acrylic copolymers. These copolymers typically contain a trace level (<200 ppm) of residual monomers. When one of these monomers may be styrene, EPS has added a Proposition 65 warning of a carcinogen to to the Safety Data Sheets (SDSs) and labels for those emulsions.

Our customers are encouraged to evaluate their use of these resins and to determine whether their coatings will require similar labeling under Proposition 65.
