Product Description

60/40 Hybrid Polyester Epoxy Resin with Excellent Leveling for Friction Gun Spraying
HH2686T is a saturated polyester resin, mainly used for 60/40 polyester/epoxy hybrid powder coatings systems.
Codes with a T indicate powder coatings made with this polyester resin that can be sprayed with a friction gun.
The friction gun is a powder electrostatic spraying equipment device. Although the friction gun coating is somewhat insufficient in the field of spraying equipment, it also has a certain market share in some industries such as the surface coating of aluminum profiles and large pipes.
How the friction gun works:
The powder is charged by the principle of triboelectric charging. The charge is generated by the collision, friction, contact and clutching between the powder and the special polymer material and nylon in the gun wall. The corona gun is a high-voltage corona discharge at the electrode tip.
After the powder leaves the friction gun, there is no external electric field, and the driving force is only the air force, and a weak Faraday effect is produced at the same time, making it easier for the powder to enter the area with complex geometry.
The chargeability of the tribogun depends on the timely removal of negative charges and the stabilization of positive charges. The timely removal of negative charges is directly related to the grounding effect of the spray gun, while the stabilization of positive charges requires selection of appropriate gun wall friction materials and modification of powder particles.
