The reaction percentage of this matting agent with Epoxy Resin is 10 : 1.

Step 1: Specify the amount of resin used in the formula (typically 50% to 60%).

Step 2: Select the gloss range you need according to the table below.

Step 3: View the suggested XG603-1A Matting Formula by changing the suggested gloss range in the calculator list below.

This matting agent is suitable for 5-60% gloss.

The table below is not certain, the degree of certain gloss also depends on the resin.

(The epoxy equivalent should be in the range of 750 - 800. Gloss will change according to the epoxy equivalent.)

For example, if it is intended to achieve (5 to 10%) gloss in a formulation with Hybrid Polyester Resin (60-40), bellow steps should be taken:
  • 1-Total amount of resin: 60 Wt%
  • 2- Dosage of matting agent: 5% (according to desired gloss)
  • 3-Type of resin: 60/40 polyester resin ( SJ 5 A)
  • 4- Consider 50 units of epoxy to react with 5 units of matting agent (Based on this fact that each unit of this matting agent reacts with 10 units of epoxy resin).
  • 5-The remaining amount of total resin is 10% (60-50=10)
  • 6- Residual amount of polyester and epoxy resin will be 6 and 4, respectively.
  • 7- Therefore, the total amount of epoxy 54% ( 54% =4% reaction with matting agent + 50%).
