Description
Composition and Properties
Hexamine crystals burn with a yellow flame and are known for their high solubility in water. This compound has been employed in small indoor fireworks, offering a safer alternative to metaldehyde, as it does not produce poisonous formaldehyde when ignited indoors.
Uses in Fireworks
In fireworks production, hexamine serves as a fuel and can be utilized in formulations requiring controlled combustion and specific flame colors. Its properties make it valuable in creating dazzling visual effects and enhancing the overall performance of pyrotechnic compositions.
Benefits in Fireworks Production
Hexamine’s main advantage lies in its ability to burn cleanly, producing vibrant colors without generating harmful byproducts. Its controlled combustion and consistent performance make it a preferred choice for pyrotechnic engineers seeking reliable and safe fuel options.
Application Techniques
Hexamine is typically incorporated into fireworks compositions in powdered form. Its precise amount and combination with other chemicals determine the color, intensity, and duration of the flame. Careful handling and proper mixing techniques are essential for achieving desired effects.
Environmental Impact
While hexamine can decompose into formaldehyde, a potential carcinogen, its use in fireworks is generally considered safe when handled responsibly. Proper ventilation and adherence to safety guidelines minimize the risk of exposure to harmful byproducts.
Safety Precautions
When working with hexamine, it is important to wear appropriate protective gear, including gloves and eye protection, to avoid skin and eye contact. Additionally, ensure proper ventilation in the workspace to reduce inhalation of fumes.
Storage Recommendations
Store hexamine in a cool, dry place away from direct sunlight and sources of heat. Keep the container tightly sealed when not in use to prevent moisture absorption and maintain its efficacy.
Quality Standards and Regulations
Hexamine used in fireworks production should meet relevant quality standards and regulations. Manufacturers adhere to strict guidelines to ensure the compound’s purity, consistency, and safety for use in pyrotechnics.
Future Trends and Innovations
As the demand for innovative fireworks compositions grows, there may be ongoing research and development efforts to explore new applications and formulations involving hexamine. Continued advancements in pyrotechnic technology may lead to exciting innovations in the use of hexamine in fireworks.

Works great for crosslinking or as a fuel. Experiments with adding higher amounts in blue stars gave good results. It does have a bit of the characteristic hexamine odor, but not as bad as other products I’ve smelled so that’s a plus. Again, packing and shipping were absolutely great.

Good chemical, good price, fast shipping!!
Cross links with phenolic resin when mixed at a 9:1 ratio by weight with phenolic resin, with 10% being the “just right” amount per article I’ve read. So if 10g phenolic, it’d be 1g of hexamine added. For proper linking the entire composition must be heated all the way through to the core, to a minimum 65c(149F) – 104c(212.2F) maximum temperature.
There is no dwell time needed once the composition is heated through to the core to at least the minimum temperature. A 3/4” star/comet takes about 65minutes to heat all way through, bigger stars/comets taking longer.
Hope this helps anyone trying to find info on cross linking hexamine and phenolic resin.
USE COMMON SENSE WHEN HEATING FLAMMABLE COMPOSITIONS, PLEASE!!!

I use Hexamine to make fire starter cubes, along with sawdust, Paraffin and petroleum jelly. The product is of the highest quality and with great prices and fast shipping, why buy anywhere else??
