SYNTHOESTER 186 HS

1 of 21 products in this brand
SYNTHOESTER 186 HS is a hydroxyl group containing, high-solid polyester resin. It is recommended to use it in combination with melamine resins and CAB for base-coat enamels. It can also be used with aliphatic polyisocyanates for air- and oven-drying 2-pack high-solid laquers and fillers with high mechanical properties, high gloss and body, and very good chemical and weather resistance. It has applications in marine transportation, marine coatings, automotive OEM coatings, metal coatings, wood coatings, and finishes.

Technical Details & Test Data

Mixing ratio with poly-isocyanates

Assuming equivalent reaction of the reactive groups (NCO:OH = 1:1), the following formula applies for the calculation of the added amount of polyisocyanate (relative to 100 parts by weight of SYNTHOESTER 186 HS, solid):
42 X 100 X 6.0 17 X NCO %
42 = molecular weight to the NCO group 17 = molecular weight of the OH group 6.0 = hydroxyl content of SYNTHOESTER 186 HS in % relative to sol
