RB788 leveling agnet is a kind of polypropylene crylic acid copolymer with amdin character group, the formed piece are 100% solid in room temperature. there are have two kind series in the marketing which has crylic acid active matter content is 30% (RB788-1) and 60%(RB788-2) . They can use for anti-weather polyester coating system with high base viscosity, and RB788-2 also can use for other coating.
Products code RB788-1 RB788-2

Its a complex with amdin character group and polypropylene crylic acid which can be provide inertia in powder coating. it wont being compatibility problem. the recipe can regulable widely.
It has nicer surface leveling effect and delible vapor bubble capability, the function can be come down to amdin character group being amelioration mix diffluence of leveling and material base.
It has lower viscidity and favorable heat stability in fusion state. it can mend lubricate capability of materials base use for powder coating.
the leveling agent has clear up gas performance in powder coating formulation can be omitted or decreased greatly with benzoin.
The dosage of leveling is about 3% or 1.5%(based on total weight) , the usage amount is lesser than other solid leveling agent. therefore the cost of powder coating is down probably.
Be applicable to any powder coating system, it can be added at the premix stage of powder coating manufacturing and extruded with the other components of formulation by any suitable extruder, then, grinding and sieve passing. the extrude temperature should be control at about 110-1200 better.
