22X-34N PE Clear Primer for Wood Spraying

22X-34N (Original HS-8706) PE Clear Primer for Wood Spraying

The 22X-34N (Original HS-8706) is an advanced PE clear coat primer meticulously engineered for the demanding surface finishing requirements of premium wood products. Specifically formulated for application on acoustic instruments, grand pianos, and high-fidelity audio cabinets, this liquid resin delivers an exceptionally smooth, crystal-clear foundation that enhances the natural grain and depth of the wood. Recognizing that manufacturing environments vary significantly across global facilities, the "X" in our nomenclature represents our tailored climate adaptability feature. We provide customized grades calibrated precisely to your factory's actual ambient temperature, ensuring consistent curing stability and optimal flow regardless of seasonal shifts. By creating a flawless, transparent barrier, this primer significantly reduces subsequent topcoat consumption while elevating the final aesthetic appeal and tactile smoothness of luxury wooden assets.

Core Performance & Characteristics：

> Exceptional air-drying capabilities that accelerate production lines, allowing for rapid handling and reduced wait times between coating layers.

> Superior sanding properties. The cured primer forms a fine, non-clogging powder when abraded, providing a perfectly leveled surface with minimal physical exertion.

> Outstanding adhesion to the substrate, penetrating deeply into the wood pores to lock in natural oils and prevent future delamination or blistering.

> Excellent overall workability, maintaining a stable viscosity during application to prevent sagging on vertical surfaces and ensuring an even, uniform film build.

Specifications of liquid resin：

The parameters outlined above represent our unwavering commitment to stringent quality control. Each batch undergoes rigorous laboratory testing to verify that the viscosity remains strictly between 300 and 500 cP at 25℃, ensuring optimal flow through standard spray equipment. The precise acid value of 10-25 mgKOH/g guarantees a stable cross-linking process when the specified curing system is introduced, resulting in a durable, crystal-clear finish.

Curing system in SPI test: Hardener AKZO CH-50: 2%;

Processing & Use formula： 

                                                         parts by weight

22X-34N Clear Primer                                          100 parts

Styrene                                                     10-15 parts

Curing agent (methyl ethyl ketone peroxide MEKPO)  1-2 parts

Promoter HS-926                                            0.5-1.5 parts

Note: The dosage of accelerator and hardener should be adjusted according to the temperature change.

To achieve the optimal finish and ensure the structural integrity of the coating, precise measurement of each component by weight is critical. The recommended dosage of the accelerator (Promoter HS-926) and hardener (MEKPO) must be dynamically adjusted in response to your facility's ambient temperature and humidity levels. During colder seasons, a slight increase within the specified range may be necessary to maintain the targeted 6.0 to 15.0-minute gel time, whereas warmer conditions dictate a reduction to prevent premature cross-linking. Proper blending ensures the resin achieves its signature milky white, semi-transparent liquid state before curing into a flawlessly clear protective layer. Our technical support team is available to assist your production managers in fine-tuning these ratios for standardized, high-volume manufacturing.

Safety, Compliance & Attention:

> Transportation should be in accordance with the regulations on transportation and handling of chemical dangerous goods in Chapter 5 of the Regulations on the Safe Management of Chemical Dangerous Goods of the State Council. The product should be stored in a cool place under 25℃, avoiding fire, isolating heat source, and sealed to prevent moisture intrusion and volatilization of the monomer.

Shelf life is 3 months at 25℃.

> The product has MSDS for reference, please read them in detail before use.

Strict adherence to these safety and storage protocols is essential for maintaining the chemical activity and performance of the 22X-34N PE clear primer. Upon arrival at your facility, the product must be immediately transferred to a well-ventilated, cool environment strictly maintained below 25℃. It is imperative to isolate the containers from any direct heat sources, open flames, or prolonged exposure to sunlight. The drums must remain tightly sealed when not in active use to prevent moisture intrusion and the volatilization of the styrene monomer, which could alter the solid content and viscosity. Comprehensive Material Safety Data Sheets (MSDS) are provided with every shipment; we strongly advise all operational personnel to review these documents thoroughly to ensure a safe and compliant working environment.
