Resorcinol glue, also known as resorcinol-formaldehyde, is an adhesive combination of resin and hardener that withstands long-term water immersion and has high resistance to ultraviolet light. working qualities. Several adhesives can be chosen for gluing. How do you mix it up? A. All solid wood and plywood used for the construction and repair of aircraft should be of the highest quality and grade. Knots greater than ¼-inch must be used with caution. Air leakage test results showed that gelatin-resorcinol–formaldehyde-glutaraldehyde (GRFG) glue has significantly more pressure tolerance than fibrin glue (p < 0.001). Forms a bond stronger than the wood itself. Other popular glues include: 1. When possible, fabricated wood components should be purchased from the aircraft manufacturer, or someone who may have a Parts Manufacturer Approval (PMA) to produce replacement parts for the aircraft. In the curing process, the formaldehyde or isocyanate reacts and creates an adhesive seam with new chemical bonds between the adhesive polymers and between the wood and the glue. Ben Owen at the EAA reports that he recently purchased some Penacolite glue from Borden, the new manufacturer of our favorite resorcinol glue. With either of these sources supplying the wood components, the mechanic can be assured of installing approved material. Once cured, modern adhesives do not contain solvents and the emissions are almost non … I don't really see any sign that blades were fused at the hub section in photos (that aren't that revealing anyway). Upland growth superior to lowland growth. Next. what method is used to prepare plywood for bending. The following defects are permitted in the wood species used for aircraft repair that are identified in Figure 1: Cross grain—Spiral grain, diagonal grain, or a combination of the two is acceptable if the grain does not diverge from the longitudinal axis of the material more than specified in Figure 1 column 3. Each propeller then goes through a rigid 56 point inspection to assure you of the highest quality, most problem free propeller available. Wood Aircraft Construction and Repairs page.

Some adhesives are … Pressing or clamping time—time during which the components are pressed tightly together under recommended pressure until the adhesive cures (may vary from 10 to 150 pounds per square inch (psi) for softwoods, depending on the viscosity of the glue). Intraoperative pulmonary air leakage is one of the most troublesome complications in … This glue meets all strength and durability requirements if the fit of the joint and proper clamping pressure results in a very thin and uniform bond line. and conversely, no loss in bond strength occurs at temperatures as low as 40°F. It is used commonly in boat building. Just trying to get a reference for painting the lamination highlights. Pin knot clusters—Small clusters are acceptable if they produce only a small effect on grain direction. Tension—forming on the upper side of branches and leaning trunks of softwood trees, tension wood is caused by the natural overstressing of trying to pull the branches and leaning trunk upright.

If any casein adhesive is left, residual alkalinity may cause the new adhesive to fail to cure properly. Easy to work with hand tools. Apparently it fell out of favour as it was susceptible to attack by bacteria so they would have been pleased to get resorcinol, a good long lasting glue that was water and UV resistant reductions are substantiated. Double spread—spread of adhesive to both surfaces and equally divided between the two surfaces to be joined. Close contact adhesive—a non-gap-filling adhesive (e.g., resorcinol-formaldehyde glue) suitable for use only in those joints where the surfaces to be joined can be brought into close contact by means of adequate pressure, to allow a glue line of no more than 0.005-inch gap. Product DescriptionApplication:Resorcinol is a kind of important organic intermediates,which is used for rubber materials, adhesive, uv absorber, dye, medicine and etc. It provides strong bonds between many wood and non-wood surfaces. Ho-wever the price for resin and phenol resin adhesives is. Somewhat low in shock-resistance. Each propeller then goes through a rigid 56 point inspection to assure you of the highest quality, most problem free propeller available. Delete. Temperatures must be above 70° for a reliable cure.

Compression—very detrimental to strength and is difficult to recognize readily, compression wood is characterized by high specific gravity, has the appearance of an excessive growth of summer wood, and in most species shows little contrast in color between spring wood and summer wood. Some find the dark color of the glue objectionable. The various species of wood listed in Figure 1 are acceptable for structural purposes when used for the repair of aircraft. Some of the more common adhesives that have been used in aircraft construction and repair include casein glue, plastic resin glue, resorcinol glue, and epoxy adhesives. May be Resorcinol glue is sensitive to temperature and will not set very well if your shop is below 70 degree F. It will set faster at higher temperatures, and plywood and other architectural structures are often pressed and clamped then put in a kiln to shorten and improve setting. inspection difficulties. It lists the strength and characteristics of the wood in comparison to spruce. RobOwens. The manufacturer’s product data sheet may define this as working time or useful life; once expired, the adhesive must not be used. Resorcinol is a 2-part glue, making high strength bonds, but is not gap filling. without carefully accounting for slightly reduced strength properties. Several forms of wood are commonly used in aircraft. Solid wood or the adjective “solid” used with such nouns as “beam” or “spar” refers to a member consisting of one piece of wood. sizes to compensate for lesser strength. These features make it advantageous for use as a general marine and aircraft use. In decades past casein glue was the aviation classic. I have a serious caution to offer about Resorcinol glue.
