Porcelain cover coat frits

Porcelain enamel is a glass of a particular chemical composition and physical nature determined for the surface protection of metal.

Enamel cover coat frit is a form of glass bonded to metal on a molecular level at high temperature.

This results in a typical and unique composite material of glass and metal, which combines the positive qualities of both materials.

Cover coat have good opacity and gloss with clean and fine surface, but they can’t be directly coated on the body metal, they require the matched ground cover coat frits. The firing temperature of cover coat frit is lower than that of ground cover coat frit.

Vitreous Enamel Frit

Vitreous enamel frit frit is a traditional coating that has been used for generations, but remains a tough modern finish.

It has impressive qualities of resistance to physical damage, heat, corrosion, ultra-violet light and yet it is compatible with many metal substrates.

It is suited to the demands of hundreds of products and capable of being decorated by several processes.

We can supply vitreous enamel frit either as frit, or ground into powder, as individual frits or blended for specific uses.

These products are for professional application, and need a heat source in the region of 800’C to fuse the enamel frit onto the metal substrate.

Reactive Ice Transparent Frit

Transparent frit provides a unique effect in fused art. The glass contains elements that react to the metal content in other colors, creating intriguing color shifts and halos around contrasting pieces.

Transparent frits are made from crushed, screened and magnetically cleaned Bullseye Fusible sheet glass. Use transparent frit for your pate de verre and glass casting projects, or add pizazz to your fusing and kiln-formed glass jewelry.

Packaged in a wide-mouth 5 lb. jar. Fully compatible 90 COE. All Bullseye Stringers, Frit and Confetti are mixable for quantity discount.

Cadmium Red Deep Pigment

Cadmium red deep pigment (PR108). Synthetic Inorganic pigment (Cadmium Sulphoselenide). Opaque. Good tinting strength. Excellent Lightfastness. Low oil absorption with slow drying rate. Suitable for all media except exterior. Used since early 20th Century.

Cadmium red deep pigment is cadmium zinc sulfoselenide (CdS, CdSe) produced by co-precipitating and calcining, at high temperature, a mixture of cadmium sulfide and selenide sulfide in varied ratios forming a partially crystalline structure with sometimes hexagonal or cubic forms. Cadmium pigments are the most durable yellow, orange and red inorganic pigments commercially available. They have excellent chemical and heat stability, and can be used in chemically aggressive environments and durable applications without color fade.

Cadmium sulfoselenide pigments were developed in response to the need for stable shades of cadmium orange to red colors. Cadmium and selenide salts are co-precipitated and then heated to 300 °C.

The use of vitreous enamel coatings

Many reinforced concrete structures on Army installations represent critical assets that are vital to storing, maintaining and transporting vehicles and material needed to support the warfighter. Unfortunately reinforced concrete can have a short service life if the reinforcement steel in the concrete corrodes.

A series of new vitreous enamel coatings that contain hydraulically-reactive calcium silicates and aluminates have been developed to provide additional protection for the steel and to increase the service life of reinforced concrete structures. The new series of vitreous enamel coatings combine a layer of alkaline- resistant basecoat vitreous enamel
with an outer coating of vitreous enamel
that incorporates dicalcium silicate, tricalcium silicate and calcium aluminate and alumino-ferrite. The basecoat protects the steel while the calcium silicates in the outer layer hydrate when placed in fresh concrete and chemically bond to the surrounding concrete paste.

The bond strength between the concrete and steel is increased two to three times that developed with uncoated steel. The enamel over the steel produces durable corrosion protection. Tests with steel stay-in-place forms demonstrate the usefulness of the vitreous enamel coating steel.
