Powdered Phenol Formaldehyde Resin with Hexamine for Thin Cut off Wheels

Product description

♦Appearance: Powder ♦Resin Type: Novolac
♦Resin Monomer: Phenol and Formaldehyde ♦ Catalyst: Acid
♦Curing Agent content: Hexamine

Phenol Formaldehyde Resin H501J is produced by condensing a molar excess of phenol to formaldehyde in the presence of an acid catalyst. This produces a thermoplastic resin. To cure this resin, a hardening agent is used, HMTA (or hexa). Under heat and pressure, it yields ammonia and formaldehyde as methylene groups to cure the resin, hence the term “two-step,” because of the two formaldehyde additions. A novolak phenolic resin has an infinite shelf life under normal storage conditions.Cured phenolic resin provides the rigidity necessary to maintain structural integrity and dimensional stability even under severe conditions.

Characteristics

1. Bonding Strength

The primary use of phenolic resin is as a bonding agent. Phenolic resin effortlessly penetrates and adheres to the structure of many organic and inorganic fillers and reinforcements, which makes it an ideal candidate for various end uses.

2. High Temperature Performance

A key characteristic of thermoset phenolic resin is its ability to withstand high temperature under mechanical load with minimal deformation or creep. In other words, cured phenolic resin provides the rigidity necessary to maintain structural integrity and dimensional stability even under severe conditions.

3. Chemical Resistance

Phenolic resins accommodate the harsh exposure of severe chemical environments. The inherent nature of

phenolic resin provides an impervious shield to protect a variety of substrates from the corrosive effects of

chemicals. Laboratory tests confirm minimal degradation from many chemicals after prolonged exposure,

often at elevated temperatures.

4. Low Smoke and Toxicity

Burning phenolic resin typically generates hydrogen, hydrocarbons, water vapor, and carbon dioxide. Phenolic resin produces a relatively low amount of smoke at a relatively low level of toxicity.

5 .High Carbon and Char Yield

Phenolic resins demonstrate higher char yields than other plastic materials when exposed to temperatures

above their point of decomposition. In an inert atmosphere at high temperatures (600° - 2,000°F, 300 -

1,000°C), phenolic resin will convert to a structural carbon known as vitreous carbon. In many ways, this

material behaves similar to ceramic and may actually contribute to structural integrity when exposed to fire

situations.

Application

Phenol Formaldehyde Resin H501J is recommended for Thin Cut off Wheels.

Cut-off wheels are used in construction and machinery manufacture. Cut-off wheels can cut various metals, organic and inorganic materials. There are many types of cut-off wheels for cutting different materials of different shapes and sizes. These are usually used in a cutting machine and used for dry grinding without coolant
