Phenalkamine hardener is a high-performance epoxy hardener, prepared from cardanol, a renewable ingredient obtained from cashew nut shell fluid (CNSL). They are produced via the Mannich reaction involving cardanol, an aldehyde such as formaldehyde and an amine.
The curing agent phenalkamine allows rapid curing at temperatures as low as 0°C, even in high humidity conditions. Their excellent moisture resistance, surface resistance, adhesion, ductility, durability and chemical resistance make them particularly suitable for harsh environments.
They are widely used in epoxy formulations for protective and marine coatings, tank linings, industrial floors and heavy duty corrosion protection systems. Phenalkamine-cured epoxy coatings have strong adhesion to substrates such as steel, concrete and other metals.
In forced-curing industrial coating applications, phenalkamine curing agents can reduce energy consumption by allowing lower curing temperatures in the oven. Their fast curing properties can also increase production line speeds, improve operational efficiency and reduce the risk of coating failure.
Phenalkamine curing agents used in protective epoxy industrial paints and industrial paints are coatings made from a two-component epoxy resin system. These coatings are known for their durability, chemical resistance, and ability to withstand harsh environments. They are commonly used in industrial and commercial environments to protect surfaces from corrosion, abrasion and chemical damage. Epoxy coatings come in many different colors and finishes, and can be applied to concrete, metal and other surfaces.
Epoxy paint cannot be used effectively without component B - curing agent, phenalkamine is a non-toxic curing agent, compatible with most Epoxy paints, the most popular are E44, E51, fast curing ability, low price, phenalkamine is a reasonable choice for many paint manufacturing businesses to reduce raw material input costs
The global coatings industry is growing rapidly under the influence of industrial expansion, infrastructure investment, the need to protect assets and increasingly stringent environmental regulations.
Vietnam is currently one of the largest cashew processing and export centers in the world. With a strongly developed factory system in Binh Phuoc, Dong Nai, Binh Duong and the Central Highlands region
Cashew nut shell oil (CNSL) is emerging as a high-potential renewable feedstock for the global biofuel and sustainable materials industry.
