Formaldehyde glue is commonly used in woodworking, veneering, and laminating due to its stiffness, resistance to moisture, and ability to bond oily woods. It has an open working time of 30-45 minutes and can be cured quickly with heat. It is stronger than yellow glue and can withstand moisture. However, safety precautions must be taken as it is a possible human carcinogen.
Formaldehyde glue, also called plastic resin, is an adhesive commonly used in woodworking. The glue can be used in veneering and laminating work. Formaldehyde glue is known for its open working time, stiffness and resistance to moisture. Industrial formaldehyde can also be used on oily woods, to which other adhesives may not adhere. While this glue may have a long working time, it can be easily and quickly cured when heat is used.
Woodworking, veneering and laminating can be time consuming. Formaldehyde glue has an open working time ranging from 30 to 45 minutes. This means that the glue will not set before this amount of time. Open working time may be extended in cooler environments, but the product should not be used in conditions with temperatures below 55°C (12.7°F).
Long working time with urea formaldehyde adhesive can be shortened in hot condition. If the temperature reaches 90°C (32°F), the working time can be reduced from five to 10 minutes. Heat can be used to decrease setting time in cold environments. Once set, colder temperatures will not affect adhesion.
Yellow glue, or polyvinyl acetate glue, is commonly used in woodworking and furniture manufacturing. Yellow glue is a semi-rigid glue, which means that the weight of the piece can pull the glue bond over time, causing a gap between adherent materials. Formaldehyde glue is a stiff glue that can withstand greater pressure and traction than semi-hard glue.
You can do veneer and laminate work on furniture that needs to resist moisture. A dining table, for example, can come into contact with moist substances from plates, glasses and crockery. Formaldehyde glue can withstand such humidity. The bond between the veneer or laminate and the underlying hardwood remains strong even in the presence of moisture.
Expensive furniture can be built with exotic woods. These woods may have oily characteristics, making adhesion difficult. Formaldehyde glue bonds these unique woods together without the need for further preparation or curing of the material. The bonds between oily woods and veneer or laminate are typically just as strong as the bonds to non-oily woods.
Safety precautions must be taken when working with formaldehyde glue. The glue is listed as a possible human carcinogen. This means that the vapors released from formaldehyde can cause cancer. Proper safety equipment, such as goggles and face masks, should be used to reduce potential health risks to people. Proper ventilation should also be used to decrease the concentration of formaldehyde in the air.
