Paint formulas

A film former may be present as drying oil, varnish, resin solution, dry resin, plasticizer, or some combination of these. A solvent may be present as free solvent or a component of varnishes or resin solutions. Pigments and additives are usually listed separately. [Pg.58]

These materials normally consist of pure film former plus solvent and additives, such as a drier and an antiskinning agent. Clear finishes may be oil and resin cooked into a varnish or a synthetic resin solution, such as an alkyd. Such finishes are normally transparent unless color is added in the form of a pigment or a dye, and they are glossy unless a flatting pigment is added. Properties depend on the oils and resins used and the conditions under which the varnish is processed. [Pg.58]

Stains contain a low amount of both film former and pigmentation, especially if they are penetrating stains. They are designed to soak into the surface to give color and some protection without forming a paint film. The so- [Pg.58]

Both prototypal questions related illustrate the need for a successhil technical service professional to have a strong understanding of the customer s apphcations and processes, within proper intellectual property considerations. This need for a thorough understanding is not always straightforward. A common example of the complications that can arise is provided from the paint (qv) industry (11). If, for instance, a calcium carbonate suppHer would like a paint manufacturer to use their material versus a competitive one, the onus is on the suppHer to show that the material can be successfully used in the paint formula of interest. However, many such formulas are held as proprietary. The technical service professional therefore does not know the components of the paint. This would lead to an unworkable situation from an evaluation standpoint save for the fact that the paint company may supply a miHbase or other intermediate form of the paint to allow a proper comparison of carbonates to be carried out. Thus mutual benefits can result and no loss of proprietary information occur. [Pg.378]

Calcium carbonate is one of the most common filler/extenders used in the paint and coatings industry. Consumer and contractor paint formulas can include products from submicrometer size to coarse mesh sizes. The main function of calcium carbonate in paint is as a low cost extender. It is also used to improve brightness, appHcation properties, stabiHty, and exposure resistance. Coarse products help to lower gloss and sheen or even provide textured finishes. The selection of product type and particle size is deterrnined by the desired performance and cost of the coating. [Pg.411]

One coat of primer, formula 84-47, followed by light gray deck paint, formula 20L. The top coat approved by the Departments of the Army, Navy, and Air Force primarily for painting decks on the interior of military vessels, conforms with the requirements of specification JAN-P-700 (2). It is not formulated to be fire-retardant. [Pg.54]

With the exception of the Observer Differences, all of these conditions can and should be controlled. If the light booth or the surround need to be painted, the paint formula is as follows PPG 80-110 Interior Latex Flat, B-46, L-2Y, 0-12. This will make one gallon of paint. Cleaning and maintenance of the reflectors and filters will keep the colors more vivid between scheduled calibration. [Pg.189]

An outline paint formula has been described and it has been shown that application presents problems which influence the formula. After application comes drying, but before this is considered, the properties required from the dry film must be discussed, since these influence the choice of method of drying. [Pg.87]

Typical emulsion paint formulae are given opposite. [Pg.146]

Mr B.M. Letsky, Industrial Finish Consultant, for the nitrocellulose lacquer formula in Table 11.2. Rohm Haas Company, Philadelphia, USA, for the acrylic lacquer formula in Table 11.2. Worlee Chemie GmbH for the water-borne air-drying formula in Table 12.1. DSM Resins (UK) Ltd for the emulsified alkyd paint formula in Table 12.5, the metallic car finish formula in Table 13.2 and the acrylic isocyanate formulae in Table 15.3. BIP Ltd for the woodfinish formula in Table 13.1. Amoco Chemicals UK Ltd for the high solids and water-based formula in Tables 13.4 and 13.5. [Pg.297]

The specific paint formula itself is also important. Too much pigment, for example, can interfere with the smooth formation of a continuous film. In fact, any imbalance or excess of paint additives can potentially affect latex film formation. [Pg.103]

Following are the properties a paint formulator m have to consider when developing a new paint formula. [Pg.108]
