How Is Non-Toxic Glue Beneficial?

Glues and other adhesives are used in products and systems that we encounter daily. Many types of glue emit harmful fumes into the surrounding environment, posing a risk to the health of people in the area. To mitigate the health risks of toxic glues, it is essential to choose a non-toxic glue product that doesn’t sacrifice performance.

What Is Non-Toxic Glue?

Many adhesives contain solvents, chemicals, and other toxic ingredients that can cause adverse health issues for the people who come into contact with them, whether these people are glue factory employees, end users, or as a result of environmental-related effects. Certified non-toxic glues are made of ingredients that are shown to be safe for human use with minimal impact on the environment.

Some of the toxic fumes, or volatile organic compounds (VOCs), in petroleum-based glues include xylene, formaldehyde, toluene, light aliphatic naphtha, and N-hexane. Breathing in toxic fumes from glues can induce an array of health issues, including headache, nausea, difficulty breathing, seizures, and may even lead to certain types of cancer.

Non-toxic glues are often water-based and thus have low VOCs, or in some cases, no detectable VOCs. Therefore, they are generally much safer to use.

Benefits of Non-Toxic Glue

Aside from being non-toxic, other benefits of non-toxic glue include:

  • Excellent bonding: Non-toxic glue forms a strong, permanent bond, with comparable strength to their less people-friendly competitors.
  • Water-solubility: Non-toxic glue’s uncured or unused residues will readily dissolve in water and can be washed away with soap and water.
  • Biodegradable and recyclable: Non-toxic glues are made from naturally occurring sources with minimal modification. Since it is made from these materials, it readily biodegrades, unlike solvent-based adhesives.
  • Can be FDA approved for indirect food contact: Non-toxic glue has no toxic components in significant quantity and are thus safe for direct human contact after cure. Therefore, it can be submitted to the FDA for testing for use in outer food packaging, provided it does not come into direct contact with the food. The FDA may even conclude that some non-toxic glues are safe enough to be used in inner food packaging in some cases.
  • Safe to handle: Products containing non-toxic glue are usually safe to handle by direct contact and, in many cases, are safe enough to be handled by children.
  • Reduced waste: Non-toxic glue reduces waste and conserves resources since it is made from natural and/or abundant materials that have undergone minimal processing and, in some cases, are designed to mimic natural processes.

Why Breezebond™?

Breezebond™ adhesive is a plant-based hot-press glue that exhibits high strength and is suitable for many wood-based applications, such as plywood and other wood composites. It is the only soy-based adhesive that does not contain petrochemical ingredients, including no additional toxic formaldehyde over natural background levels.

Breezebond™ is suitable for the wood products industry because it is made from abundant and low-cost starting materials, its strength compares well to traditional adhesives, is safe to work with, and allows end customers to meet sustainable building goals.

During the production process, a compatible reagent is added to modify the groups of amino acids in the soy mixture, making them behave like natural protein glue. After this step, depending on the application, an oxidizing agent can be added to help form bonds to boost the performance of the glue. This gives the bond even higher strength and better moisture resistance.

Advantages of Breezebond™ Adhesive

BreezebondTM adhesive has several advantages over other types of glue. Some of these pros include:

  1. It is made from low-cost, abundantly available sources.
  2. It is comprised of a single component with an optional trace additive incorporated before use.
  3. It has a low viscosity and meets various wet and dry strength industry requirements.
  4. It is tested at independent laboratories for strength and VOC content.
  5. It does not require an expensive investment to convert from traditional glue.
  6. No petrochemical ingredients are added during the manufacturing process.
  7. It has a longer shelf-life than other soy-based glues (3 months).

Understanding How Plywood Is Made

What is Plywood? 

Plywood is a very versatile material that is used throughout a wide range of interior, exterior, and structural applications. It is created by gluing together three or more thin layers of wood veneer using a plywood adhesive, resulting in a flat sheet of wooden material. 

How is Plywood Made? 

Most people have heard of plywood, but how is it made? The specific process depends on whether you are making hardwood or softwood, but the main steps of the plywood manufacturing process include:

Step One: Selecting the Log

The first step in the plywood manufacturing process involves selecting a log from a tree type that meets the physical and aesthetic requirements of your application.

Step Two: Debarking and Cutting

The logs are loaded into a debarking machine, which removes the bark using sharp-tooth grinding wheels or high-pressure water. The debarked logs are then carried down a conveyor where a large circular saw cuts them into standard-sized sections. 

Step Three: Peeling the Logs

Before the veneer can be peeled and cut into sheets, the logs must be soaked and heated to soften the wood. The amount of time it takes depends on the type of wood, the diameter of the log, and other factors. Then, the softened blocks of wood are fed into the peeler lathe.  

Step Four: Creating A Ribbon of Wood

The peeler lathe rotates the softened woodblock as a full-length knife blade peels a continuous sheet of veneer from the spinning block. When the diameter of the block shrinks to about 3 or 4 inches, the block is ejected from the lathe. The ribbon of wood that is produced can be immediately processed, wound onto rolls, or stored in long trays.

Step Five: Cutting and Stacking

Processing the ribbon of wood entails cutting it into usable widths. The sections of veneer can then be sorted, stacked, and dried to reduce their moisture content and shrink them before gluing. 

Step Six: Gluing

Once the sections of veneer emerge from the dryer, they are ready for gluing. The back veneer is fed through a glue spreader, which applies an even layer of glue. Then, the short sections of core veneer are placed crossways on top of the glue and the whole sheet runs through the glue spreader again. The face veneer can then be placed on top of the glued core. For long-lasting and sustainable results, use Specialty Organics’ BreezeBond™, a formaldehyde-free adhesive, to bind inner core layers and face veneer.

Step Seven: Pressing

After the gluing process, the sheets are then pressed together in a hot press. They are squeezed together under high levels of pressure while being heated to high temperatures. The pressure ensures good contact between layers and the heat works to cure the adhesive for maximum strength.

Step Eight: Trimming and Sanding

The rough sheets are sent through a set of saws, which trim them into their final dimensions. The sanding process can differ depending on the grade of the sheets. For higher grade sheets, both the face and back are sanded, whereas intermediate grade sheets are only spot sanded.  

Why Use BreezeBond™ as Your Plywood Glue? 

BreezeBond™ offers a wide range of benefits when used for manufacturing plywood. For example, BreezeBond™ is a formaldehyde-free adhesive which features high strength. This makes it suitable for producing plywood while reducing your net carbon footprint and meeting sustainability goals. This low viscosity, hot press adhesive also meets wet or dry strength adhesion standards for a variety of industries.
