Serving Through Technology

A cost-effective heat barrier as well as a color coating. "Necessity is the mother of invention". This statement has never been truer than today. The field of thermodynamics has experienced heightened interest from the energy conservation community. One of their major goals is to reduce, save and otherwise create new ways of conservation. We at Delta Plastics found that one branch of our chemistry, "which has been in use for over 30 years", could be called upon to perhaps answer many more applications than ever dreamed possible in the past. In this light, we present Delcoat®.


Thermal conductivity; the subject has been discussed extensively, but few actual tests and procedures have been written. What has been written has been statistical and theoretical. We at Delta Plastics Co., in conjunction with the California State University Fresno Engineering department, and associates, are presenting testing methods and results. Reflecting the heat does not necessarily translate into energy savings and cost reduction. Delcoat® does. The utilities as well as the United States Department of Energy suggest that every 1°F drop in interior temperature maintenance produces a 3% savings on energy. The testing yielded a 7°F interior heat transference differential which produces an equipment cycling reduction of approximately 21%. This means when a structure’s walls and roof are coated with Delcoat®, your energy consumption, and therefore costs, could be reduced by as much as 21%. This is a significant savings on your energy bill. This energy savings will allow the engineer to modify a building’s amenities to better serve their clients and still meet the California Title 24 requirements. It will also help meet new Federal mandates for energy conservation and reduce the production of green house gasses. Why just paint? Instead of painting, thermal coat it. We can manufacture most colors. In addition the testing showed that a coated structure would enjoy a 12°F reduction in internal temperature versus an uncoated structure. For those who do not have temperature control equipment this would produce an appreciable cooling effect. We hope you find the results of our tests as exciting as we do. We invite you to contact us with your opinion or questions.


Temperatures of the concrete surface were taken prior to applying the heat source. The temperature of the concrete was measured by using a digital reading temperature gun. Two tests were conducted on the concrete specimens. The first test consisted of directing heat on the test specimens for approximately 9 hours and recording the temperature of the concrete on the front side in which the heat was applied and the back side for a heat transfer. The results of the test are presented below. The evaluation was performed by conducting a test on two similar concrete specimens. The concrete specimens were approximately 12-inch square and approximately 4 inches thick. The weight of the specimens was approximately 45 pounds. The heat source for the test consisted of a 250 watt infra red light bulb placed in a 12 by 12 open-face concrete box. Two identical heat sources were constructed, one for each concrete specimen. The heat source was directed on the face of the concrete specimens. The heat source apparatus was placed an equal distance from the concrete specimens.

The second test consisted of applying heat to the concrete specimens and measuring the heat rise on the back side of the test specimen over as period of time. After approximately 4 hours, the heat source was removed and the front side and back side temperatures were recorded. In addition, the decline of temperature on the back side of the concrete specimens was recorded. The results of the test are presented below.

The Delta Delcoat® material is specifically designed for sunlight refraction. The Delta Delcoat® can be used for both concrete and metal surfaces. Delta Delcoat® is very unique in that the chemistry of the material does not promote reflection, but rather refraction which limits the heating element of the sun’s heating rays to reach the face of the substrate or parent material. This superior refracting material has been used for over thirty years in various applications and is now available in a cooling formulation for both concrete and metal walls with outstanding color and physical structure retention. Delta Delcoat® is available in various colors such as white, grays, browns, yellows, greens and beiges. Custom color matching is also available upon request.


The Delta Delcoat® is applied at a rate of 125 square feet per gallon. It can be applied by roller, brush, or common spray equipment. In addition, clean up requires only water.


This material is available in 5-Gallon pails, 1-Gallon cans, and 1-Quart cans packaged by weight as follows:
