Linseed oil putties

The mastic type sealants include hand-applied systems based on linseed oil (putty), gun-applied oil-based systems, using one or more drying oils and gun-applied butyl systems based generally on liquid polyisobutylene (PIB) with oils and solvents. These function primarily as gap fillers to prevent the ingress of dust, rain and wind in substantially non-moving joints. ... 

Hard putty n. (1) Linseed oil putty hardened with htharge or basic lead carbonate. (2) A quick setting putty containing water and plaster of Paris. 

Oil based caulking compounds are supplied in knife and gun grades. Gun grades are viscous semiliquids whereas knife grades are more viscous and are similar to mortar in consistency. A simple linseed oil putty has a composition of 12 parts oil and 88 parts calcium carbonate filler. The sealants can be appUed at temperatures between 40 to 100°F (4 to 38°C). Below 40°F, the viscosity becomes too high for easy working, and above 100°F, the viscosity drops sufficiently for sagging to occur. 

Fillers. Micronized carbonate whiting is the preferred mineral fill for putty and caulking compounds based on linseed oil or plastic, and vinyl-based floor coverings. It comprises 20—60% of the raw material mix (see Fillers). 

This cement may be applied on cracks but not on joints because it becomes as hard as stone on standing. A litharge putty may be prepd by mixing 73 ps of litharge, 8 ps of flock asbestos and 19 ps linseed oil. The mixt sets in about 7 days and resists acids up to about 50% strength. The so-called "German putty consists of 70 ps quartz flour, 8.5 ps fluosilicate, 1.5 ps clay in 20 ps of water glass (NaaO 20, SiOa 60 and... 

Oil Absorption. The oil absorption gives the mass or volume of linseed oil required to form a coherent putty-like mass with 100 g pigment under specified conditions. The mixture should just not smear on a glass plate. For standards, see Table 1 ( Oil absorption ). Materials and apparatus rough glass plate, spatula with steel blade, raw linseed oil. 

GLA DTG PUTTY can be made by adding enough linseed oil to whiting (pure finely ground chalk) to make a paste. After it has dried it can be sanded. LIME PUTTY is slaked lime and water mixed thickly and left to stand to form a smooth paste. 

Use Filler in rubber, plastics, and paper coatings putty (with linseed oil) whitewashes sealants. 

Modified phenolic resins are condensation products of the resol type which contain other starting materials besides phenol and formaldehyde (e.g., acrylic monomers). The phenolic component itself is often modified (alkyl- or arylphenols). Modification with rosin is the most important one. The compatibility of phenolic resins with other binders can be substantially improved by modification. Rosin-modified phenolic resins may be combined with linseed oils and alkyd resins. Examples of use include putties, priming coats, rust protection paints, and colored topcoats.

Absorption, oil n. Oil absorption of a pigment or extender is recorded as the amount of vegetable drying oil required to convert a given mass or volume of the dry powder to a very stiff putty-like paste, which does not break or separate. It is more usually expressed as the pounds of refined linseed oil required for 100 pounds of pigment or gTOOg. 

Putties. Used in the glazing of wood sash, putties are generally based on linseed oil, filled with calcium carbonate or blends of calcium carbonate and titanium dioxide. Formulations are shown in Table 4. Containing 11-12% oil, they dry by oxidation to hard, inflexible joints with little movement possible. Putties are supplied as bulk compounds for knife application to wood or metal sash. Most putties are used in industrial, commercial, and maintenance glazing however, significant quantities continue to be used by homeowners in residential glazing. 

Glazing - Linseed oil based putties were extensively used in the past for glazing applications. Newer glazing sealants include polysulfide, silieone, and acrylic emulsion. Butyl tape, polysulfide and silicone sealants are used in the manufacture of insulated glass. Safety glass door and window panels ean be made by sandwiching a layer of polyvinyl butyral film between two layers of glass. 

P. are products with an - adhesive function but are used predominantly to fill and seal gaps. The traditional product is glazier s putty, which is based on drying oils and is a mixture of 450 parts whiting and 40-80 parts of (boiled) - linseed oil.
