Heat Resistant
Silicone Resin can help organic resin systems reach continuous heat resistance up to 600°C when 30% silicone is introduced into the formulation. This is valuable for coating factories producing powder coatings for metal parts, high-temperature equipment and surfaces exposed to long working heat. Better heat resistance helps reduce coating failure, color change and customer complaints after application.
Reactive Compatibility
This resin contains silanol groups and can be cold blended or copolymerized with organic resin systems according to formulation needs. For coating manufacturers, this makes heat resistance and weatherability improvement easier to test without rebuilding the full raw material system. Better compatibility also helps reduce trial waste when technical teams adjust resin ratios during product development.
1、Silanol Functionality
The silanol functional groups support reactivity during coating formulation adjustment. This structure helps formulators improve compatibility, curing response and long-term coating stability when working with organic resin systems. Buyers should select the proper grade based on the final coating temperature, resin combination and application target.
2、Solid Resin Form
Silicone Resin is supplied in solid form, making it suitable for powder coating systems where dry handling and formulation consistency matter. Solid resin is easier to manage during blending and compounding than liquid materials that may create dosing or storage problems. For coating factories, this supports cleaner material handling and more controlled batch preparation.
3、Grade Selection
Available grade indicators include PCT-9013, PCT-9018 and PCT-6618, with silica content around 50 to 64 and Tg values around 41°C to 48°C. These grade differences help buyers compare heat resistance, compatibility and coating performance before testing. Proper grade selection can reduce repeated trials and make production validation more efficient.
Polyester Resins
Polyester Resins
Polyester resins are essential film-forming materials widely used in powder coatings due to their excellent weatherability, stable curing behavior, and strong mechanical performance. Their molecular structure can be precisely engineered through controlled acid value, molecular-weight distribution, and end-group design, enabling balanced flow, gloss, and outdoor durability.
TGIC-Cured Polyester Resin System
Polyester Resins
TGIC-cured polyester resin systems are recognized for their outstanding outdoor durability, strong crosslink density, and long-term weather resistance. Compared with other curing technologies, TGIC systems offer a broader processing window, stable extrusion behavior, and consistent film formation even under demanding production conditions.
Primid (HAA-Cured) Polyester Resin System
Polyester Resins
Primid polyester resin systems provide an environmentally friendly curing route with zero formaldehyde release and excellent color stability.
●PCT9505 provides balanced overall performance with superior indoor durability and a clean, uniform film finish.
●PCT9106 offers a versatile curing profile, supporting high-gloss formulations with HAA or matte finishes when combined with GMA resins.

Key Applications
Silicone Resin is a high-performance polymer designed for powder coatings requiring exceptional thermal endurance, oxidation resistance, and long-term stability.
Polyester resin is the core film-forming binder used in modern thermosetting powder coatings. It provides the structural backbone of the coating film, determining essential properties such as weatherability, hardness, mechanical strength, chemical resistance, and long-term durability.
Epoxy resin is a high-performance thermosetting polymer widely used in metal coatings, protective finishes, electrical insulation, and corrosion-resistant systems.
Curing agents are essential reactive components used in thermosetting powder coatings. They chemically crosslink with polyester or epoxy resins to create a solid, durable, three-dimensional coating network.
FAQ Use & Operation
How Does Storage Condition Affect Resin Stability?
Temperature, humidity, and inhibitor effectiveness play major roles in resin shelf life. High temperatures may cause premature crosslinking, viscosity increase, or accelerated aging. Moisture can trigger hydrolysis in certain polyester systems or reduce flow. To maintain stability, resins should be stored in cool, dry environments with effective inhibitors and proper packaging protection.
What Technical Support Do You Provide During Formulation Development?
We offer resin selection recommendations, pigment/additive compatibility checks, sample extrusion testing, and application validation to ensure reliable, scalable production.
Can You Support Custom Curing Windows for My Production Line?
Yes, we can tailor TGIC/HAA cure kinetics, adjust resin reactivity, and provide formulation guidance to match your oven temperature, line speed, and product requirements.
How Do Your Resins Help Improve Outdoor Durability?
We design polyester backbones with UV-stable structures, controlled MW distribution, and optimized end-group chemistry to enhance gloss retention and anti-yellowing performance.
What Can You Do If My Formulation Has Flow Or Leveling Issues?
Our technical team can analyze resin melt behavior, additive compatibility, and extrusion conditions to recommend an optimized resin grade or adjustment to improve surface appearance.
How Do You Ensure Batch-To-Batch Consistency for Your Resins?
We use DCS-controlled reactions, MES batch tracking, and strict acid-value/molecular-weight monitoring to guarantee stable curing performance in every production batch.
