Brand

SYNTHALAT

End Uses

2K (2 component) Coating, Primer, Solventless & High Solids Coating

Compatible Substrates & Surfaces

Aluminum, Metal, Steel

Usage

In combination with aliphatic polyisocyanates air-drying and oven-drying two-component primers with excellent filling properties, quick drying and good adhesion to steel, aluminum and zinc that give good results in the condensed moisture test and salt spray test. These types of two-component primers are used preferably wherever maximum corrosion resistance and adhesion are required.

Mixing ratio with polyisocyanate

Assuming equivalent reaction of the reactive groups (NCO:0H = 1:1), the following formula applies for the calculation of the added amount of polyisocyanate (relative to 100 parts by weight of SYNTHALAT-A 200, solid): 42 X 100 X 6.0 17 X NCO % 42 = molecular weight of the NCO groups 17 = molecular weight of the OH groups 6.0 = hydroxyl content of SYNTHALAT-A 200 in % relative to non-vol. components Best results are obtained with a mixing ratio of 100 parts by wt. of SYNTHALAT-A 200 (form in which delivered) to 64 parts by weight of Desmodur N 75%. An undercuring or overcuring of up to 20% has only little influence on film properties.
