Exolit® AP 750 is a non-halogenated flame retardant based on ammonium polyphosphate as main component, which develops its effectiveness through phosphorus/nitrogen synergism. In contrast to similar competitive material, it shows high processing stability. Exolit® AP 750 differs in its mode of action from non phosphorus-based flame retardants (e. g. brominated, chlorinated or mineral FRs like ATH) by achieving its effect through intumescence. Material containing Exolit® AP 750 will foam on exposure to flame. The carbon-rich foam layer so formed will protect the polymer and in many cases the substrate below through its heat insulating effect, reduces further oxygen access and prevents dripping in case of a thermoplastic based formulation. Beyond the primary effects on fire behavior such as reduction of flame propagation rate, rate of heat release, dripping behavior, residual lengths of test specimens after flame tests etc., positive secondary fire effects such as low smoke density, no release of corrosive off-gasses, lower formation of toxic smoke gasses are of great interest.

Exolit® AP 428 is a fine-particle ammonium polyphosphate produced by a special method. The product is largely insoluble in water and completely insoluble in organic solvents. It is colorless, non-hygroscopic and non-flammable. Exolit® AP 428 differs from most other commercial products in the following ways, greatly reduced solubility in water lower viscosity in aqueous suspensions, lower viscosity in PU polyol suspensions.

Exolit® AP 422 A is a fine-particle ammonium polyphosphate (phase II) with less than 0.1% melamine. The product is largely insoluble in water and completely insoluble in organic solvents. It is colorless, non-hygroscopic, non-flammable, and classified as SVHC-free under current regulations.

Exolit® AP 435 is a fine particle ammonium polyphosphate (phase II) optimized for low viscosity in aqueous suspension and intumescent coatings. The product is largely insoluble in water and completely insoluble in organic solvents. It is colorless, non-hygroscopic and non-flammable.

Exolit® AP 740 is a white free flowing powder. It is a non-halogenated additive flame retardant based on ammonium polyphosphate which develops its effectiveness through phosphorus/nitrogen synergism. Exolit® AP 740 differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access.

CRAYVALLAC® LV is a high performance, micronised amide wax rheology modifier suitable for very high-solids and solvent-free applications.CRAYVALLAC® LV overcomes those difficulties which exist with hydrogenated castor oil based rheology modifiers e.g. seeding and false-body. Consequently, coatings formulated using CRAYVALLAC® LV exhibit an enhanced performance such as controlled flow behavior, ease of application and excellent sag resistance. Its very high efficiency even when activated allows to reach very strong shear thinning that can result either in very high sag resistance or interresting balance between viscosity and sag resistance. Therefore CRAYVALLAC® LV is for instance highly recommended in the case of solvent free coatings with relatively low viscosity. It prevents the use of specific equipment for the application that are necessary with more viscous solvent-free coatings.

CRAYVALLAC® PA3 XAF 20 is an alcohol-free pre-activated amide wax supplied in xylene. It is a rheology modifier in paste form with high efficiency (optimum sag resistance and viscosity).CRAYVALLAC® PA3 XAF 20 is supplied in the form of crystalline fibres. In a coating system, these fibres form an interacting network. This network gives rise to the shear thinning rheology of the final coating. This shear thinning characteristic provides a very high viscosity under the low shear rates associated with sedimentation, and a low viscosity at the much higher application shear rates. The net result is excellent control of sedimentation combined with ease of application.

CRAYVALLAC® SUPER is a high performance, micronised amide wax rheology modifier suitable for a wide range of solvent-based, high-solids and solvent-free applications. CRAYVALLAC® SUPER overcomes those difficulties which exist with hydrogenated castor oil based rheology modifiers e.g. seeding and false-body. Consequently, coatings formulated using CRAYVALLAC® SUPER exhibit an enhanced performance such as controlled flow behavior, ease of application and excellent sag resistanceIts smooth viscosity recovery will help to achieve high film thickness without compromising a good levelling.

Exolit® 855 is a proprietary mixture containing liquid partial phosphoric acid esters for intumescent transparent fire protection applications for wood. The clear liquid is fully soluble in water, non-hygroscopic and non-flammable.

Exolit® AP 423 is a fine-particle ammonium polyphosphate produced by a special method. The crystal modification is phase II. The product is largely insoluble in water and completely insoluble in organic solvents. It is a white powder, non-hygroscopic and non-flammable.

CRAYVALLAC® EXTRA is a high performance, micronised amide wax rheology modifier suitable for high-solids and solvent-free applications with very high robustness. It is especially recommended in 2K epoxy primers for its high temperature tolerance.CRAYVALLAC® EXTRA overcomes those difficulties which exist with hydrogenated castor oil based rheology modifiers e.g. seeding and false-body and that were maximised when activation was performed at high temperatures.

Exolit® AP 740 F is a white free flowing powder.
