BECKOPOX EP 386W/52WA is an internally plasticized solid resin-Type 1-dispersion with improved shear stability, e. g. for water reducible fast drying anticorrosion primers and coatings for plastics. BECKOPOX EP 386W/52WA is an internally plasticized type 1solid epoxy resin as aqueous dispersion. Formulated together with adequate curing agents such as e. g. Beckopox EH 613w or VEH 2188w it is suited for corrosion protection primers with very good adhesion to most metallic substrates. It is also suitable for use in single coat and decorative systems for metallic substrates. For optimium corrosion protection it is recommended using 80 % of the stoichiometric curing agent not contain functional groups capable of reacting with epoxy groups.

MACRYNAL VSM 2570/70BAC is a high solids content at application viscosity- Good drying speed. Good adhesion to metals. Very Good mechanical properties, Good gloss and Good outdoor durability. Macrynal VSM 2570 is a hydroxy functional acrylic resin cross-linkable with aliphatic polyisocyanates to formulate air drying and forced drying 2-pack high solids coating systems. In pigmented topcoats (pigment/binder = 1 : 1) a solids content of 65 % at application viscosity of 55 s (efflux time DIN EN ISO 2431, 4 mm, 23 °C) can be achieved. To ensure that optimal properties are obtained it is necessary to have complete crosslinking. For stoichiometric (equivalent) crosslinking (NCO : OH = 1 : 1) approx. 100 parts per weight Macrynal VSM 2570 (f.o.d.) require approx. 21 parts per weight Desmodur N 3390 (Covestro). in combination with amines like diethyl amino ethanol (approx. 0.2 %, based on solid resin). Potlife is thereby reduced, however. Dilution Suitable diluents are butyl acetate, methyl isobutyl ketone, 2-methoxypropyl acetate or aromatic solvents like solvent naphtha 150/180. Anhydrous solvents as well as solvents free of hydroxy functional groups should be used in the presence of isocyanates. Pigments Inert pigments and extenders are suited for pigmentation. Pigments with basic surface treatment can act as additional catalyst and shorten the potlife even more.

Additives To improve levelling ADDITOL VXL 4930 is recommended. ADDITOL VXL 6212 has proved to be an effective wetting agent.

MACRYNAL SM 513/60LG is an excellent mechanical properties and chemical resistance, high gloss. Fast drying two pack systems, in paricular for primer surfacers for car repairs and for general industrial applications. In combination with aliphatic polyisocyanates Macrynal SM 513/60LG is recommended for at ambient temperature drying or forced drying two pack systems. The principal application field is automotive refinishing and high-grade industrial paints. Due to its rapid initial drying Macrynal SM 513 is especially useful for the formulation of primer surfacers. Automotive refinishing clearcoats based on Macrynal SM 513 must be stabilized with light stabilizers.

MACRYNAL SM 565/70BAC is used for air-drying and forced drying high-solids two pack coatings with high gloss, outstanding mechanical properties, excellent chemical resistance and outdoor stability. In combination with aliphatic polyisocyanates, pre-eminently with Desmodur N 3390, Macrynal SM 565 is used for air-drying and forced drying high-solids two pack coatings. The principal application area is high quality automotive refinishes and high-performance industrial coatings.
