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.

Palmer Holland, Inc.Hostavin® 3055 liq.
  • Principal:Clariant Additives
  • Functions:Antioxidant, Light Stabilizer
  • Chemical Family:Hindered Amine Light Stabilizer (HALS)
  • End Uses:Clearcoat, Plastic Coating, Solventborne Paint, Waterborne Coating, Wood Coating
  • Features:Excellent Solubility, Excellent Stabilization Properties, Good Compatibility, Low Molecular Weight, Low Volatility, Outdoor Durability
  • Physical Form:Liquid
Hostavin® 3055 liq is a low-molecular radical scavenger of the type hindered amine light stabilizer (HALS) for solventless and solventborne paints. On principle, it is also suitable in waterbome coatings. Hostavin® 3055 liq is characterized by its excellent solubility, broad compatibility, low volatility and good stabilization efficiency. It can either be added to the ready-to-use paint or incorporated during the paint production. However, as all UV stabilizers, it ought not to be added to the mill-base. Depending on the requested stabilization effect, the addition rate should be in the range of 1.0 to 3.0 %. All concentrations relate to active UV stabilizer on solid resin. Pre-trials, covering various concentrations, are highly recommended. As a non-substituted HALS, Hostavin 3055 liquid is slightly basic and because of this can have an influence on the crosslinking of binders. In such a case, the altemative use of Hostavin 3058 liquid is recommended. Since HALS is highly recommended for all outdoor durable coatings, the need for an additional UV absorber strictly depends on the UV transmittance of the final coating. Inorganically pigmented coatings with good hiding power do usually not require an additional UV absorber, clear coats certainly do.
