Segment Applications
For passive fire protecting systems / intumescent coating systems


Charmor PM40 is a micronized polyol based on pentaerythritol.  
Charmor PM40is used in conjunction with an acid donor and blowing agent to produce high performance intumescent coating.  
Charmor PM40 is also suitable for use in formulating intumescent sealants, thermoset unsaturated polyesters, thermoplastic engineering resin parts, and standard thermoplastic resin parts.  

Intumescent coatings work as follows:


-The thermoplastic binder melts upon exposure to the heat of the fire to allow further chemical reactions to take place in the softened matrix
-The acid donor (often a salt of polyphosphate) decomposes to form polyphosphoric acid
-The Polyphosphoric acid reacts with Charmor PM40 to form polyphosphoric acid esters
-The esters decompose to form a foamable carbon matrix
-The blowing agent (often melamine) releases gases that cause the carbon matrix to create a foam that hardens to form a tough insulating char barrier that adheres to the substrate


Charmor PM40 is particularly suitable for waterborne and solvent-borne intumescent coatings. 
The particle size of the Charmor product used has an impact on the nature of the foam.  
Smaller particle sizes yield thicker char foam.

The synthesis of Charmor PM40 involves reacting four moles of formaldehyde and one mole of acetaldehyde in two differentiated steps. 
The first is an aldol condensation to give pentaerythritose. 
Then, the aldehyde obtained is subjected to a crossed Cannizzaro reaction, whereby one molecule of the pentaerythritose is reduced to pentaerythritol, which is then separated. 
The raw pentaerythritol is dissolved again and subjected to high-temperature acid hydrolysis, then purified in an activated carbon bed, concentrated and crystallized.

Charmor PM40 was first reported in 1891 by German chemist Bernhard Tollens and his student P. Wigand. 
Charmor PM40 may be prepared via a base-catalyzed multiple-addition reaction between acetaldehyde and 3 equivalents of formaldehyde, followed by a Cannizzaro reaction with the fourth equivalent of formaldehyde to give the final product.


Handling and Storage
Charmor PM40 is a non-hygroscopic product. 
However, it should be stored under dry conditions, in sealed bags and protected for direct sunlight. 
Avoid handling that forms dust clouds.

Uses
Charmor PM40 is a versatile building block for the preparation of many polyfunctionalized compounds. 
Derivatives of pentaerythritol are components of alkyd resins, varnishes, polyvinyl chloride stabilizers, tall oil esters, antioxidants. 
It can be found in transformer oil, plastics, paints, cosmetics, and many other applications.

Polyester derivatives
Charmor PM40 is a precursor to esters of type C(CH2OX)4. 
One such derivative is pentaerythritol tetranitrate (PETN), a vasodilator and explosive. 
The trinitrate derivative is called pentrinitrol (Petrin). 
The tetraacetate is called normosterol (PAG). 
The polymer cross-linking agent pentaerythritol tetraacrylate.

Charmor PM40 is used as a fire retardant, such as in plastics.
Charmor PM40 produces a thick carbon barrier upon heating, protecting the surface substrate.

Charmor PM40 is one of the most common main active components in intumescent paints and coatings. 
Charmor PM40 acts as a carbon donor and together with an acid donor, most commonly ammonium polyphosphate (APP), and a blowing agent, most commonly melamine.

As quaternary alcohol, Charmor PM40 is easily generated by esterification acid and ester, so most of the classes used in alkyd resin coatings raw materials, mainly used for architectural coatings and automotive primer.
Charmor PM40 is used to esterify with nitric acid to generate Charmor PM40 tetranitrate (also known as PETN) in 5~15 oC in industrial, which is a kind of high explosives and bigger than TNT explosive, most as a booster, or mix with TNT. 
A lot of PETN has been used in the second world war. 
Charmor PM40 reaction with rosin acid can produce rosin Charmor PM40 ester, which can be mixed with drying oil and is a kind of coating with better hardness, water-resistance and weather resistance, can be used in the ink of varnish, floor, etc. 
By esterification condensation Charmor PM40 or glycerol with phthalic anhydride, fatty acid can make an alkyd resin coating. 
The use of different kinds and different amount of fatty acid can improve the properties of alkyd resin, making it a suitable coating of various kinds in need. 
Charmor PM40 is widely used as a coating on the surface of the metal, wood, as a bridge, railway, derrick, building and other aspects of commonly used industrial paint and architectural paint. 
Because the price is low, alkyd resin of reactants, easy modification, strong adaptability, well comprehensive, it has become the backbone of the coating industry since 1927.
Charmor PM40 is often used in the coating industry, is of alkyd coating raw material for the production of highly cross-linked coating using four hydroxyls, the coating has good hardness and colour, can improve the hardness, lustre and durability of the coating film. 
Used as varnish, paint and ink production of rosin ester raw material, and can be used as flame retardants, drying oil, aviation lubricating oil. 
Charmor PM40 fatty acid ester is polyvinyl chloride (PVC), plasticizer and stabilizer are also used in medicine, pesticide, lube oil manufacture.
Charmor PM40 acrylic ester generated by Charmor PM40 and acrylic acid has a fast-drying property, it is widely used in radiation-curing coatings and quick drying of printing ink, water-soluble alkyd resin, the polymer can be used as adhesive. 
The C6~C10 fatty acid ester of Charmor PM40 is mainly used as an advanced lubricant for steam turbine, automobile engine etc. 
The ester produced by this product with C10~C12 fatty acid can be used as a plastic plasticizer, which has low volatility and high ageing resistance; 
Reaction with epoxy compound and its product can be used as a surface-active agent, widely used in detergent and cosmetics and perfume raw materials; 
Charmor PM40 is used as the material of explosives, medicine, pesticides, organic intermediates, etc.
