Phenol Formaldehyde Adhesives and Laminates Find Application in Paints and Bonding Solutions for Flooring, Ceiling and Wall Coverings, and Others
Phenol
formaldehyde resin is synthetic polymer formulation used in the manufacture of
high-pressure adhesives and laminates for a variety of applications. It is also
utilized to manufacture a range of products, including friction stirrers,
solvent transfer tapes, adhesives for paper, fiberboards, dry lubricants, sealants
for adhesive labels, chemical and paper weights, epoxy resin types,
polyethylene and thermoset resins. Phenol formaldehyde adhesives and laminates
find application in wooden chipboard, construction, electrical equipment,
decorative articles, and others.
Phenol
formaldehyde is utilized in the manufacture of adhesives for wood products,
varnish, rubber and plastic products, varnish and epoxy resins, drywall, paint,
and varnish mantles. It is also utilized as an additive in a number of paints
and bonding solutions for flooring, ceiling and wall coverings, marine &
automotive paints, sealants, glue, and adhesives for furniture. Phenol formaldehyde adhesives and laminates form a part of a broad category of materials used
in industrial processes, such as thermal insulation, automotive seals,
soundproofing, and bonding.
Phenol
Formaldehyde resin is commonly used in the manufacture of thin wall and plywood
materials, as well as bonding acrylics and polyurethane foams. They are used to
strengthen the bond between various materials and to give them sufficient
strength for aesthetic and functional purposes. Although a common ingredient in
building materials, there are a number of health hazards associated with the
use of phenol formaldehyde resins. The most immediate hazard associated with
the substance is its volatile nature, which can result in serious skin
reactions and respiratory issues if exposed to high concentrations. It is this
potential health hazard that has prompted the U.S FDA to ban the use of phenol
formaldehyde resins in certain products. To engender the safe application of
adhesives, wood adhesives must contain low concentrations of volatile organic
compounds. Formaldehyde exposure limits is 3 ppm (total weight average) in the
U.S., 2 ppm (threshold limit value (TLV)) in the U.K., and 1 ppm (TLV) in
Germany and Switzerland.
Phenol
formaldehyde adhesives and laminates can help to protect wood from termites,
help make the finishing surface of plywood and urethane easier to maintain and
increase the life span of artificial wicker furniture. While the material does
not have a low absorption rate like VOCs, they still contribute to a low
airborne concentration. This means that although phenolic resin and urea
formaldehyde resins may cause nose and throat irritation when inhaled, these
irritations are mild and temporary.
