GLUING AMMONIUM-SALT-TREATED SOUTHERN PINE. WITH RESORCINOL-RESIN ADHESIVES By. SCHAEFFER, Chemist. 1 Forest Products Laboratory, Forest Service U.S. Department of Agriculture Introduction. During the past 10 years, considerable work has been done on the gluing of fire-retardant-treated wood.

Gluing ammonium-salt-treated southern pine with resorcinol-resin adhesives. Madison, Wis.: U.S. Dept. of Agriculture, Forest Service, Forest Products Laboratory, (OCoLC) Southern pine lumber, treated with ammonium salt fire retardants, was glued with resorcinol­ resin adhesives under conventional gluing conditions at room temperature.

In block-shear evaluations, the treated specimens yielded a lower joint. Gluing ammonium-salt-treated southern pine with resorcinol-resin adhesives / by R.E. : R. Schaeffer. Joints of Southern Pine, made with a resorcinol-resin adhesive of commercial manufacture formulated for gluing wood treated with a fire retardant (NH4 salt), passed the minimum requirements of American Commercial Standard CS for shear strength and wood failure.

Joints made with six ordinary phenol-resorcinol or resorcinol-resin adhesives were Author: R. Schaeffer. resorcinol resin adhesives. while. lowering the pH of the adhesive. Both these factors could change the length of the curing period required to achieve a quality adhesive joint with bonded fire-retardant-treated wood.

In work reported on the gluing of ammonium salt-treated southern pine, a period of. months was permitted between.

Resorcinol Glue. For most amateur boatbuilders Resorcinol is an echo from the past. They might have heard it mentioned in an old book, or some crusty woodworker might have raved about it. Few have ever seen it on sale and fewer have used it. Here is some information.

If I were to say I have a glue that can glue wood. Is immensely strong. Borden Resorcinol adhesives can be spread by mechanical glue spreaders with either steel or rubber covered rollers, or hand spread with a stiff bristled brush, roller or spatula.

Except as provided by law no liability is accepted for any loss or damage or consequential loss arising from the use of the Company's products, or from the use of the. Aerodux 2 Pack resorcinol resin adhesive.

Totally waterproof, resorcinol resin is recommend for not only for laminating of structural timber components but also for demanding and critical applications such as veneering of fire doors.

Used extensively for bonding difficult timbers and suitable for marine use. At HF gluing a glue spread of g/m² single-sided is recommended.

At other applications: g/m². Difficult-to-glue wood or hardwood may require double spreading in amounts of g/m² on each side.

Abstract. This chapter reviews and presents a perspective of the special qualities of the resorcinol/formaldehyde resins as adhesives for wood and in a variety of other, commercial or potential uses, with the exception of their use as reinforcing resins and bonding agents in vulcanizable rubber compounds which was dealt with separately in Chapter : Hans Dressler.

Pre-Catalyzed Powdered Urea Resin - 5 Pound Pail Applications: Excellent general-purpose wood adhesive for solid wood gluing and veneering. Good for applications requiring unquestioned Type II moisture resistance. Best choice for low/moderate volume veneering and curved millwork.

Can be cold pressed, hot pressed and cured by RF. Correct about the hardener. The glue is still sold by Axminster (for one source) My father was a designer in the plywood era and built many boats with Aerolite.

But it is not as durable as more modern adhesives. I don't think anybody uses it now in aircraft. I started using resorcinol glue in wooden aircraft work back in the early 70s.

In addition, resorcinol is a critical ingredient in wood bonding adhesives requiring room temperature cure and waterproof performance, and resorcinol is an essential raw material for many specialty chemicals including ultraviolet light absorbers, fire retardants, polycarbonates, agricultural chemicals, urethane elastomers, dyestuffs and others.

This same adhesive is. still available however, under the Cascophen G name (see link below) and is still made by Hexion as was the private label Weldwood brand.

Detailed Product Description: A high performance, two-component adhesive formulated to provide strong, durable bonds in severe service applications. Once cured, Resorcinol. So Resorcinol the daddy of all adhesives is the second cheapest, beaten only by Aerolite. Resorcinol glue line is much thinner so less adhesive will be used in any glue job than epoxy increasing cost savings.

It can be wiped off with a wet sponge before cured unlike epoxy. Most epoxy smells and can lead to sensitisation, resorcinol much less so.
