primer

n.

1. An elementary textbook for teaching children to read.
2. A book that covers the basic elements of a subject.

[Middle English, devotional manual, from Norman French, from Medieval Latin prīmārium, from neuter of prīmārius, first, from Latin, from prīmus. See prime.]

prim·er² (prī'mər)
n.

1. A cap or tube containing a small amount of explosive used to detonate the main explosive charge of a firearm or mine.
2. An undercoat of paint or size applied to prepare a surface, as for painting.
3. Genetics. A segment of DNA or RNA that is complementary to a given DNA sequence and that is needed to initiate replication by DNA polymerase.

A material used for the first coat of paint or as the prime coat in a protective coating system. Primers are designed to promote adhesion of the coating system to the substrate, to furnish a good base for further coatings, and to prevent attack on the substrate by air, water, or other materials.

Wood primers are formulated to give maximum adhesion and to provide adequate flexibility for adjustment to dimensional changes that occur when wood swells or shrinks because of changes in moisture content. Primers used as the undercoat for enamels must provide a smooth film and permit easy sanding.

Metal primers must provide excellent adhesion by mechanical anchorage or chemical bonding. Modern corrosion-resistant coating systems applied over steel contain inorganic or organic zinc dispersed in a suitable vehicle. Zinc is attacked by the electrochemical corrosion process preferentially before steel, and protects the steel substrate by this sacrificial property. Prime coat materials for nonferrous metallic substrates usually are generically related to materials used in subsequent coats.

Primers for porous surfaces such as concrete must seal the surface adequately to provide a uniform base for future coatings.

Primers are always pigmented. In clear finishes the coat which performs this function is described as a sealer, an under-coater, or a wash coat. See also Corrosion; Paint; Pigment; Surface coating.

n. 1. a cap or cylinder containing a compound that responds to friction or an electrical impulse and ignites the charge in a cartridge or explosive.

2. a small pump for pumping fuel to prime an internal combustion engine, especially in an aircraft.

See the Introduction, Abbreviations and Pronunciation for further details.

1. A paint, applied as a first coat, which serves the function of sealing and filling on wood, plaster, and masonry; inhibits rust and improves the adhesion of subsequent coats of paint on metal surfaces.
2. A thin liquid bitumen solvent; applied to a roof surface to absorb dust and to improve the adhesion of subsequent applications of bitumen.
3. A cartridge or container of explosives into which a detonator or detonating cord is inserted or attached.

Oligonucleotide which is hydrogen-bonded to the template strand of DNA; required for the replication of DNA by polymerase.

• random p. method — a method of labeling DNA in vitro.
• p. walking — an orderly method for sequencing DNA which involves obtaining some sequence, then making an oligonucleotide primer to the end of the sequence obtained and using it as a primer for the next sequencing reaction and repeating this until the whole sequence is determined.
