Norman’s Tuff-Coat™ services consist of three separate and distinct materials and processes. Each are uniquely suited to the lamp type on which they are applied.
Silicone “Polysiloxane Fluoroelastomer”
INCANDESCENT LAMPS
COMPACT FLUORESCENTS
HALOGEN LAMPS
Advantages of Silicone include:
Norman Lamps, Inc. utilizes Silicone™ elastomer for applications requiring a thick, highly durable, high temperature, low cost glass containment system. Norman Lamps, Inc. utilizes specialty silicones produced by General Electric Company used in a wide variety of industrial applications. Norman has adapted this product and reformulated it in order to produce an optimal coating material for shatter containment of lamps. This reformulated Silicone™ material, in conjunction with our exclusive application and curing process, produces a superior finished product as compared to Chinese and other domestic silicone processes.
Standard thickness of our Silicone™ coating is approx. 10mil. Although our standard single application of Silicone™ is more than sufficient, Silicone™ can be applied a second time producing extreme coatings as thick as 20mil.
Silicone™ elastomer is very versatile and used on a wide variety of coated lamps that Norman produces.
Advantages of P.E.T.™ include:
P.E.T.™ is ideal for use on fluorescent tube lamps of all sizes, outputs and applications. Unique properties of P.E.T.™ include U.V. protection against yellowing, fading and clouding. P.E.T.™ is extremely strong, puncture resistant and lightweight. It is applied to the fluorescent tube by Norman’s custom developed and automated process which is capable of producing up to 2,000 coated 4 foot tubes per hour or up to 1,000 coated 8 foot tubes per hour.
Norman’s exclusive process completely and securely encapsulates the entire glass tube including the end caps. In the event breakage, the glass, phosphors, and mercury remain trapped within the P.E.T.™ protective envelope. The lamp can then be safely removed and disposed of properly with no harm to people or surroundings
P.F.A. “Perfluoroalkoxy Resin” ™
I.R.HEAT LAMPS
 R40
Advantages of P.F.A.™ include:
P.F.A.™ is a very unique material that combines extreme temperature resistance with high clarity, excellent adhesion and high impact strength. P.F.A.™ also known as Teflon™, has been in widespread use for over thirty years in various industries and applications throughout the world. Its combination of properties makes it ideal for use as a shatter containment coating especially on very high surface temperature light bulbs.
Norman uses P.F.A.™ coatings primarily on lamps used in the food service industry. It provides for safe and effective shatter protection over food, preparation areas and people.
Teflon™ is a registered trade mark of the DuPont Corporation.
