Hello
I have a question about mixing pigment pastes in our PX90 resin. In the TDS i read:
"In all cases, pigments should be added to Part A first, using the minimum amount of pigment required to achieve the desired strength of colour"
" The pastes are made from pigment powder that has been extensively milled into a small amount of base resin in order to produce a liquid paste thatcan be easily dispersed into the casting resin"
and it should be typically 2-6% by weight. ( add max 6% extra AB100g+P6g or 6% of the total AB94g+6g?)
So how should I count?
A: Same amount Part A and B and add max 6% pigment of total weight? (A100g + B100g + P12g)
B: Same amount Part A and B and add max 6% pigment of just Part A? (A100g + B100g + P6g)
C: Calculate together pigment and Part A and after that add Part B? (A100g + P6g +B106g) (6% of Part A)
D: Calculate together pigment and Part A and after that add Part B? (A100g + P12g +B112g) (6% of total resin?)
E: ...
I also see that different color have different density, So the amount of Base resin in the pastes is diffrent.
I want to mix the color pastes directly in the bottle with Part A, I think I can add max 60g pastes to 500g Part A.
And after this just calculate the colored Part A and Part B 1:1?
But how do I get the best performance?
I usually use epoxy and there is the mixing accuracy important!
