Benzoin
Benzoin, also known as benzoin or diphenyl ketone alcohols, is the most common degassing agent in powder coating. When the powder coating is melting, benzoin consume the oxygen in the bubbles, reducing the bubble diameter, causes the pressure inside the bubble increased, so that the speed of polymer dissolved nitrogen is accelerated, and bubble contraction is accelerated, the small molecule compounds escaped before the leveling forming film, thereby eliminating the coating pores and other small pinholes or trichopores.

Product feature:
1.It can eliminate air bubbles and pinholes of powder coating, without affecting re-coating and printing.
2.Benzoin is easily yellowed under high temperature, so we need to control the dosage.
3.It can be used for all kinds of powder coatings.

Dosage:
This product is used by added to involve in extrusion, the use level is 0.3~0.8% by weight based on total formula.
